Mass Effect 2 Guide

This page contains a full walkthrough for the main missions of Mass Effect 2.

In an attempt to cut down the length of this page aim will be made to provide hints/tips and links to greater length pages with specifics.

Note: Changes from Mass Effect
There are a few main differences from Mass Effect that returning players should pay attention to. Most of them are introduced in the initial mission, which serves as a tutorial.
 * You do not automatically go into cover by moving up against an object. To get into cover, you have to get next to an appropriate object and then press [Space] on the PC or (A) on the 360 to get into cover. If you are sprinting towards an object you can take cover behind you will instantly do so when you reach it.
 * Instead of simply climbing on top of low cover, you are now able to simply flip over it if it is small enough with [Space] or (A).
 * Gunfire has changed dramatically. The guns now behave more like real life firearms. This means if you are trying to hit a moving target you need to lead your target. Damage calculations are no longer dependent on skills or levels.


 * Weapons now have an ammunition mechanic, in the form of ejectable heatsinks. All small arms use the same types of heatsinks; heavy weapons utilize power cells. The overheating mechanic in the first game has been removed; certain tech skills can still briefly disable weapons.
 * Most interactions are now done with [Space] rather than [E] on the PC but operate the same on the console.
 * The leveling system has been significantly overhauled, resulting in characters having from 4 to 6 skills to level instead of 15-20. Each skill has 4 levels, with the fourth evolving the skill in one of two ways, usually either strengthening the skill, or causing it to have an area effect, although each is different.
 * The game has done away with weapon skills, making all weapons 100% effective at the start of the game. This has a significant effect on weapons like sniper rifles, which no longer have scope bob.
 * Tech and Biotic powers can now arc over cover to hit their targets, no longer requiring direct line of sight to use them. They can however still miss.
 * Instead of Intimidate and Charm skills, your ability to pick persuasive options in dialogue is determined directly by your Paragon or Renegade score.
 * In addition to Paragon and Renegade dialogue choices, there are also Paragon and Renegade interrupt options. These are signified by a flashing red or blue icon during a cutscene; press the appropriate mouse button or trigger to engage in the interrupt. There is usually a limited window of time during which the interrupt can be triggered. Interrupts do not have Paragon or Renegade score prerequisites, but award large numbers of Paragon or Renegade points.
 * Upgrades are now permanent rather than interchangable. However, the method of obtaining upgrades has changed. Rather than simply purchasing upgrades or finding them on corpses, you now must either find the upgrade blueprints on missions, asking your teammates about potential upgrades, or purchase upgrades in stores. Once you have Mordin on your team, you can go to his research lab and create the upgrades using resources that you find on missions and while scanning planets. Upgrades purchased in stores do not have to be 'built' in the lab.

Note: Loyalty Missions
Each character you can acquire for your party has a corresponding 'loyalty mission'. Completing this mission successfully is required to gain the party member's loyalty, and unlocks the party member's fourth power and an alternative costume.

Loyalty missions become available as the game is played. Yeoman Kelly will remark to the player that a character wishes to speak with Shepard, and the loyalty quest will be added to Shepard's quest list. Talk to the character in question and agree to solve his, her, or its problem. Loyalty quests require that the character in question be part of Shepard's squad for the duration of the quest.

Note that there are two situations in which loyalty can be lost. If this happens, the loyalty level of the character will be reset to 'normal', but the alternate costume and fourth power remain. Both situations can be resolved (in an idential manner) in a way that does not cause any loss of loyalty, but this requires a substantial Paragon or Renegade score.

Jack and Miranda
After completing both Jack and Miranda's loyalty missions (in either order), you will be summoned to Miranda's office in order to stop the two from fighting. Jack is angry that Miranda refuses to acknowledge Cerberus' mistreatment, while Miranda insists that the abuses which Jack suffered were committed by a rogue branch. A sufficiently high Paragon or Renegade score is required to keep both squad members' loyalty; taking one character's side will result in the other character losing her loyality. If this does happen, a nearly maxed-out Paragon or Renegade score will allow the player to regain the squad member's loyalty through a conversation option later on.

Tali and Legion
After completing both Tali and Legion's loyalty missions, you will be summoned to the AI Core in order to defuse a tense situation. Tali is angry that Legion is trying to send data about the quarian fleet back to the geth collective, and is threatening it with a pistol. Again, a sufficiently high Paragon or Renegade score is required to keep both squad members' loyalty.

Prologue: Save Joker
The SSV Normandy SR-1 is under attack from an unknown enemy. The ship is taking catastrophic damage and the crew have begun evacuating. A member of the crew, Kaidan Alenko, Ashley Williams or Liara T'Soni, informs you, Commander Shepard, that the ship's pilot, Joker, is reluctant to leave. After you convince Kaidan/Ashley/Liara they must abandon ship and save the crew, you are tasked with convincing Joker to leave.

As you gain control of Shepard, walk through the blazing hallways keeping to either the left or right and up a set of stairs where you will reach an airlock. Opening this door leads you to a damaged Command Deck, now exposed to open space as the roof has completely disintegrated. Walk forwards towards the cockpit, eventually reaching a kinetic airlock where you will find Joker reluctantly giving up against extremely unlikely odds.

A cutscene begins as you carry Joker into an escape pod. Before you can enter the pod, an energy beam separates you, forcing you to eject Joker by himself. Another explosion sends you flying into open space where you soon realizes your suit is quickly losing air. You struggle for a brief moment before losing consciousness.

Prologue: Awakening
Walk to the locker to obtain a pistol and armor. Miranda Lawson will introduce herself over the radio and give Shepard instructions.

Use through cover command to avoid damage from the explosive and then surmount the cover.

Proceed through the next few rooms where you will encounter a few "light mechs" they will be the easiest targets you will find in this game, it might be a good idea to knock them down and kill them for the Brawler achievement. Needless to say Overload and hacking would make this part a lot easier for you, if you are on a harder difficulty.

There will be recordings by Miranda and Dr. Wilson about their experience reviving Shepard, nothing else of much note.

Eventually you will meet Jacob. After clearing the room with Jacob and a little bit more dialog, Shepard and Jacob will meet up with Dr. Wilson, after some dialog you will head forth toward the shuttle bay and face a few more enemies. The mission ends when you arrive at the shuttle bay.

Freedom's Progress
Upon arriving at the colony, proceed through the door and make your way through the colony, killing any LOKI and FENRIS mechs that you encounter. Watch out for the one LOKI mech that is folded up inside one of the colony buildings, next to an locked wall safe.

Eventually, your squad will meet and confront Tali and a group of quarians. After talking to Tali, continue out the door and note the combat drones flying past your squad. Enter the next building and prepare to fight, then open the door. Assault and rocket drones will attack your squad- use Miranda's Overload ability to severely damage the drones, and make sure to stay under cover in order to avoid rockets.

Proceed, defeating more drones. Eventually, Tali will contact you and tell you that the other quarians rushed ahead. Make your way to the large door; order your squad mates to take cover at the indicators on each side of the door, and take cover yourself behind the middle barricade. Once you are in position, Tali will open the door.

Watch as the YMIR mech obliterates Tali's quarian friends, and prepare for battle. The mech is protected by shields and armor, and is armed with a rocket launcher and machine gun. Make sure to stay behind cover, as even brief exposure to the mech's weapons will kill you. If you are injured, make sure to remain under cover until your health and shields regenerate. The mech will move towards its target; make sure to move around the boxes to stay out of its line of sight, and use Overload and Pull to weaken the YMIR. Once it is dead, scan the broken mech for a heavy weapons upgrade, and check the two buildings to either side.

Finish up by opening the door and entering the building, where the delusional quarian is watching a bank of screens. A Paragon interrupt allows you to shut off the screens and interrupt his incoherent babbling. Listen to his description about the colony attack. Miranda will insist that the quarian be taken into custody for interrogation and debriefing, but Tali wants to take him back to the Flotilla. Choose either option to end the mission.

Recruit: Miranda
She joins you at the start of the game

Loyalty: Miranda
When Miranda escaped from her father, she also kidnapped from him her baby sister, a "twin" as she called her. Miranda then hid her from him on Illium. Her mission entails going to Illium and helping Miranda to move her sister and family to a new location. When you get there, you find that mercenaries have discovered her and you fight your way through them to meet up with Miranda's old friend, who you find has betrayed Miranda after learning that she had kidnapped her sister. He will tell Miranda that only he knows about her sister, her father has yet to be informed. Miranda will then shoot him although you have a Paragon option to stop her. After a final fight, you will find her sister unharmed and waiting with her family for a transport. Miranda will want to leave, although you have the option of convincing her to talk to her sister and letting her know she exists and loves her.

Recruit: Jacob
He joins you at the start of the game

Loyalty: Jacob
Jacob recieves a message he believes was sent by the Illusive Man that informs him that a distress beacon from Jacob's father's ship has been discovered after 8 years. You quickly leave for the planet and discover the wreckage of the ship and the A.I. After talking with the A.I. and exploring the ship, you come to discover some rather disturbing facts. After the ship had crashed, Jacob's father was promoted to captain as the captain had died during the crash. Shortly after landing on the planet, they discovered that the plant life affected their brains, making them stupid and in the case of the men, violent. You also find out that Jacob's father had forced the crew to eat the plants on the planet, while the officers used the supplies of the ship. Jacobs father also divided up the women among the officers. After fighting your way through the crazed crew and the robots, you find Jacobs father, who is at first relieved to be rescued until he realizes that his rescuer is his son. After berating his father, you have the option of either subduing him and leaving him for the Alliance to pick up and prosecute, leaving him stranded on the planet in to deal with the mess he has created as his punishment, or giving him a pistol, which he will use to kill himself after you leave.

Recruit: Archangel
Archangel is Found on Omega. After you acquire information from Aria T'Loak in Afterlife (she is expecting you) about joining a mercenary group, you may sign up to "fight" Archangel. To do this, go into the the private room in Afterlife (this will be directly to your left when you enter the club). You have to apply for a freelance spot to attack Archangel. Once you're done applying, you'll start to walk out, passing a young-looking, gun-wielding man. You will overhear him ask about applying to fight. At that point, an opportunity for a Paragon interrupt appears. If you take it, you'll disable the cheap pistol and walk out of the room (If you do this, you'll later get a private message from the teen at your private terminal on the Normandy, thanking you from stopping him). Exiting the club, there is a small alcove with vehicles that look very much like Citadel Rapid Transport vehicles in it. A Turian wearing Blue Suns armor is standing guard. When you're ready, you may speak with him, and he'll take you to Archangel's base (It is highly suggested that you prepare yourself well for the Archangel mission, as once you get to Archangel's base, there is no returning until the mission ends). You will then be transported into a mercenary encampment, where you can talk to several of the mercenary leaders and gain valuable insight into their operations. As you make your way throught the hallways, check for footlockers containing cash and raw materials. In addition, you will be given the oppertunity to disable to the mech and/or dropship. Do this. It makes the upcomming fight much easier. However shortly after you do this, you will be ordered to begin your assault. Your assault entails you running across an open bridge as Archangel picks off your freelancer compains one by one. After making it across the bridge, you confront Archangel. He removes his helmet and reveals himself to be Garrus.

After a small disscussion over events to occur, the mercenaries begin their assault. Shepard and his team have to defend Garrus and his position from waves of mercs, including a massive battle walker. After a few waves are cut down, the mercenaries begin drilling their way through the sealed passageways below. Shepard takes his team below ground to reach 3 sets of blast doors in order to lock them off for good. After a long firefight, Shepard makes his way back up stairs were the mercs are preparing for their final assault. After defeating a krogan battlemaster, the fighting stops, and Garrus reccomends making a break for it across the bridge. Just as your about to leave, a dropship appears and guns down Garrus. Winning the fight is tough, but with enough engineering and biotic abilites, Shepard will prevail. As you run towards Garrus' lifeless body, he begins to wake up. You return to the normandy where he has a hell of a scar but survives and is ready to fight.

For special additional dialogue, acquire Grunt first and bring him along, and then talk to Garm, the leader of the Blood Pack mercenary gang, before engaging in the mission proper. Picking the right dialogue options results in Garm taking out a gun and blasting the head off the vorcha standing next to him.

Loyalty: Archangel
While on Omega, Garrus was betrayed by a member of his squad named Sidonis and sent on a wild goose chase while mercenaries killed his unit. Later on, Garrus recieves intel that someone on the Citadel named Fade hid Sidonis. Once you arrive that the citadel, you meet with a Volus pretending to be Fade. After a conversation with him, you learn that Fade is actually, C-Sec officer Harkin, from ME1. You then take the rapid-transit to the previously closed off Factory District, where you battle through mechs and Blue Sun forces to reach Harkin. After a confrontation with Harkin, he sets up a meeting between Shepard and Sidonis. During the meeting, you can either help Garrus and facilitate Sidonis's assassination, or inform Sidonis and spare his life.

You must first fight through several Blue Suns before you reach his clinic. He will ask you to release the cure for the plague through the ventilation systems, and only then will he join your squad. Adding Dr. Mordin opens up the research laboratory on the second deck of the Normandy that you were previously restricted from entering.

Fight your way through krogan and vorcha to the environmental controls for the district. Along the way, make sure to turn off the beaten path and save Mordin's assistant. Upon arrival, a vorcha reveals that the Collectors are behind the plague. Once there, follow EDI's instructions to place the cure in the console in the center platform. Then go to the east and west fan controls, fighting more Blood Pack vorcha and krogan on the way. After you activate both fans the mission is over and you are back in Mordin's office, ready to return to the Normandy.

Loyalty: The Professor
On Tuchanka, one of Mordin's former STG associates has been "kidnapped" and Mordin asked you to save him. Talk to the "Scout Chief" in the Urdnot Camp. He'll lend you a truck to transport you to where Mordin's student is being held. Fight your way past the kogan and mercs until you find Mordin's old associate, who has not been kidnapped, but is instead working on a genophage cure, riddled with guilt. After the confrontation, return to the Normandy.

Recruit: The Convict
The Convict Aka Jack Subject Zero is found on the prison ship Purgatory Once the player arrives at Purgatory, they meet the Warden, who claims that his job is to keep the galaxy clean from criminals. However, you quickly learn that he is only interested in selling the criminals to line his pocket book and quickly attempts to capture Shepard and sell him to a client. After fighting your way out, Shepard releases Jack, who proceeds to start destroying the Purgatory. Following her, you eventually find the Warden, who has shielded himself with a number of shield generators. After destroying the generators and killing the Warden, Shepard tracks down Jack and convinces her to join him.

Loyalty: The Convict
Jack, being Jack, wants to blow stuff up! Specifically she wants to blow up the old Cerberus base on Pragia (Dakka System/Nubian Expanse) where she grew up. Of course, some mercs have other ideas and they'll try to get in your way. As you fight your way through them, hit all the conversation points and old computers to find out that Jack's the truth about her childhood was a little different than she remembered. Eventually you get to Jack's old cell, where you find Aresh, one of Jack's "classmates". He explains that, as bad as Jack had it, the other kids had it worse. Jack will either kill him or not. Afterwards, walk around Jack's cell and learn more about her experiences.

Recruit: The Assassin
On Illium, go see old shipmate Liara T'Soni, now a full time information broker. Liara will direct you to another asari woman, who will then transport you to a construction site where Thane has an assassination target. It is a good idea to search the tower as there are trapped Salarians who offer Paragon/Renegade interrupts. Throughout the tower, you will encounter Eclipse troops and mechs; Eclipse troops are fond of techs and rocket launchers, preparing for long/mid ranged fights is a good idea. Fight your way to the top of the towers and across the skybridge to find Thane's target. When you get there, a short conversation ensues before Thane drops in and kills everyone. Mission accomplished.

Loyalty: The Assassin
For Thanes loyalty mission he will ask that you help him find his son on the Citadel, who has followed in his fathers footsteps and become a assassin, and make amends.

You can find mouse outside the Darkstar club. Talk to him and he will say that the sons target is a local anti-human politician. After a very awesome cut-scene you will be placed on catwalks running the length of the route. Follow the politician easily seen by his bright red Krogan bodygaurd and press a every time there is a box to update Thane. After this you will arrive at the politicians apartment as the son attempts the assaisination. chose the Paragon option to have Thane and his son have a nice long talk.

Loyalty: The Warlord
Bring Grunt before the Krogan clan leader in Tuchanka, if you kept Wrex alive in Mass Effect 1, he will be the clan leader. Grunt will be instructed to take a series of tests before a structure called the Keystone. The Keystone will send out 3 shockwaves, one at a time in varying strength. The first shockwave brings waves of varren, standard melee units. Second shockwave brings some kind of firebug that explodes when shot. Third wave brings a thresher maw that shoots acid and burrows to one of three places roughly every 10 seconds. Any cover aside from concrete will break in one hit from the acid blast. To beat the final level, the player has two options. The first option is to wait out the 3 minute timer, or to kill the worm within the 3 minutes. Killing the worm will trigger a scene involving another clan of Krogan attempting to recruit Grunt. A fight will ensue against a group of 6 or so Krogan. Killing them will result in the end of the mission.

Recruit: The Justicar
TODO

Loyalty: The Justicar
When you get the quest,you have to go to Omega and go check on one of Mornith's latest victims Nef. Head to the appartments and find Nef's grieving mother. After a shorty conversation with her, you are allowed to search her appartment. Read her holograph journel's last entry to discover she went to the Afterlifes VIP section and met a salarian there. The final words were she was supposed to meet her the next day. Following this, you will travel with Samara to the back entrance of afterlife. She then tells you the only way to draw her out is for you to lure her into taking her back to her appartment. You cannot be armed and will be in grave danger as you won't be able to resist her temptations, and must be carful. Procede into Afterlife. (Very important... you must save at this point. It is extremely easy to fail and you will have forfeited the quest and all your time) You must now gain Morinth's attention. This area isn't too big and is just a small semicircle with a few lounges, a bar, and a dance floor. It is reccommended to have a high paragon or renagade skill, however it is not required. Go to the bartender and tell him to order a round of drinks. Then go and dance with someone on the dance floor. It really doesn't matter what you do but you must do some useless tasks in order to draw her attention. After two or three things are done, you will instanly go into a cutscene where Morinth tells you to come to her private booth. This is the trickiest part of the quest. You must "interst her" or she will simply say "the least i can do is buy a round of drinks for the blah blah blah convestation." There are five subject choices you can choose from. You will have to choose 3. Don't choose the ones about family or the Justicar. The other 3 will bring you into conversations about those topics. It is best to be as dark and twisted as possible, instead of heroic and mighty. It may take you a few tries, but if your successfull on all three subjects, she will invite you back to her appartment. Spend some time examining all her stuff before you talk to her. After engaging in converstation, Samara will burst threw the door and a fight will ensue. Samara will tell you t the end of loyalty quest, you can choose to kill The Justicar (Samara) and replace her with Morinth. Morinth would be loyal to you when you obtain her and her fourth skill is Dominate, an extremely useful skill for the last mission. However, it is reccomended to keep Samara as she is overall more powerful, with better biotic damage, and skills.

Recruit: Tali
TODO

Loyalty: Tali
When Tali is accused of Treason by the Migrant Fleet, Shepard and team has to travel there to attempt to clear her name. She is put under treason for alegedly sending live Geth parts to Migrant Fleet compromising its security of one of its science ships. Shepard and team has to attempt to take back that ship to clear her name. In the mean time, they find evidence that clears Tali's name, but points to the recklessness of Tali's father and his team, which may have caused the incident. Shepard has the option of turning in the evidence. Depending on how Shepard talks afterwords, Tali is either exonerated or expelled and joins Shepard at the Normandy 2.

Recruit: Legion
During the mission on the derilict Reaper after destroying the power core you can choose whether or not to take Legion with you. If you choose to take Legion with you then when you return there will be a discussion in the briefing room between Miranda and Jacob. Choosing to reactivate Legion will then allow the player to go to the ships AI core and reactivate Legion. Choose to allow him to join during the conversation and he will join.

Loyalty: Legion
After a while, Legion will inform you that geth actually are ambivilant towards organics and those fighting organics are "heretics" following the Reapers or, as they call them, "The Old Machines". Legion will tell you that the heretics are developing a virus that will turn all geth into followers of the Reapers and asks you to head to an old, heretic-held quarian space station in order to destroy the virus threatening the peaceful geths. You need to fight your way to the central computer core. Once there, Shepard can decide whether to reprogram the virus and use it to free the heretics from Reaper-control or to destroy it and the space station with all heretics on it. If reprogramming is chosen, Legion will inform Shepard that the heretics will return to the geth and their memories incorporated.

Recruit: Veteran (DLC)
Zaeed Massani is found on Omega. After completing your first mission on Freedom’s Progress, the Illusive man will tell you to go to Omega to find Mordin Solu., Zaeed Massani will be found right outside the Docking Area along the passage way. Zaeed Massani will join your squad after you talk to him.

Loyalty: Veteran
You will receive a Mission on Traveling to Zorya. After walking/running thought the forested areas, you will encounter your first enemies, Blue Suns Troopers, pyro, heavy (using the ML-77 Missile launcher) and a Fenris Mech. Using overload on the Pyro will immediately kill him. There will be a Medi-kit around behind cover. After the fight a cut scene come when reaching the bridge. Continuing down to the Gatehouse there will be a crate of Refined Palladium. Again another cut scene will pop up when opening the door. There will be 2 enemies after the cut scene when reaching the cross section, and to the right there will be another crate of Refined Palladium. After, opening the door another cut scene will pop out. The cut scene added 11 Renegade for me.

No more cut scenes from now unil the end. There will be a Salvage(+6000 Credits) to the right side of the room after killing your first 5 enemies, going down the passage way there will be a Research Terminal (gives a updated on your Squad assault rifles’ damage). Going on there will be 9 enemies to kill. Continue on and again there will be a loot on Refined Palladium. Down the hallway there will be a M-451 firestorm(only given by downloading the DLC), which is basically a flamethrower. There will be 2 enemies and a Weapon Locker with power cells right beside.

Now this is where the fun kicks in. Enemies including the YMIR Mech will come after you. After waves of enemies the YMIR Mech will come last. Do not forget the Medi-kit; it is useful! The place where the Blue Sun Troopers spawn, the left and the right have some good stuff for you. (Top Left side doors, Salvage (+6000 Credits). Top Right side doors, Salvage (+6000 Credits)). Continuing on there will be a last cut scene.

Credits earned, Renegade path;

Its worth adding that the Paragon path is more rewarding in this mission; it adds a short side trip, during which you can pick 2 more 6000 credit containers as you go around stopping the fires, and it doubles the final reward.

Reaper IFF
This mission will pit you against husks, abominations and a few Scions. If you find yourself walking toward a group of explosives, it is probably an ambush site where mobs of husks and abominations will rush you from the edge of the platform. There are several weapon upgrades sidelined throughout this level so remember to search. Halfway through the mission, Joker will call and inform you that the Reaper threw up shields. You will then be tasked with destroying the mass effect core of the Reaper. As you are advancing toward the core, a cutscene will trigger showing a single geth soldier with N7 armor kill a few husks around you. The player will then fight until the actual core where the geth will be knocked out by husks. The players job from here on is to destroy the glowing blue mass effect core while fighting off infinite waves of husks. Missiles are strangly misdirected by the core and firing one will result in the missile flying to the left or right. After destroying the core, the player will be given the choice of bringing the geth back to the Normandy. If you choose to do so, the geth may be recruited and become known as Legion.

After this mission, you should save before moving into the Omega 4 Relay. And complete all loyalty and upgrades if you want all your crew members to survive the last mission (someone dying may not have much impact on the rest of this ME2 game though...)

Upgrading the Normandy
Upgrading your ship will save some of your crew members. The upgrades that matter are the shields, the armor, and the cannon. for each upgrade you do not have you lose one team member. Jacob, Tali, and Garrus provide these upgrades. The upgrades also determine who dies and when.
 * Shields: Tali/Legion/unknown; I don't know what happens if they are both in your current squad to take down the oculus. They/she are/is vaporized when the drive core explodes due to stress


 * Cannon: Thane/Legion/unknown; You lose a party member when the collector ship attacks you


 * Armor: Jack/Unknown; You lose a party member when you crash.

Suicide Mission
There are three stages to this mission, during which you will have to choose members of your team to perform certain duties. Picking an inappropriate character for those tasks will result in someone permanently dying after the first or second session.

If you have chosen Morinth over Samara in Samara's loyalty quest, the skill Dominate is your best friend in this part because it allows you to control unshielded collectors - if you haven't noticed by now, enemies always target the closest target. On the other hand, AI Hack is no longer useful. The following is the combination needed to avoid anyone dying (provided that the Normandy is properly upgraded and all crew members are loyal).

First Session: You will have to fight several collectors and press forward to press 8 different buttons alongside a path beside the tube. The last few buttons are time-sensitive so you should clear the enemies as soon as possible. It may be advisable to save your game before you press the last button in case you pick the wrong character for the next session. The mission immediately ends after pressing the final button, so if time is running out it may be worth it to run to the button and press it even if there are enemies remaining.
 * a specialist technician is required to crawl in some tube (Pick: Tali or Legion. Don't pick: Thane, Jacob, Mordin or Garrus as they will die.)
 * a leader is required for the second team (Garrus/Miranda/Jacob, anyone else will get your specialist technician killed.)
 * your team - you will be fighting against Collector Drones, Harbingers, and several Collector Assassins

Second Session: The person you have chosen to hold a shield will erect a dome-shaped biotic shield encapsulating the squad. It will move slowly and you should move slowly within the shield. The biotic person will stop 3 times on the way where you will need to fight off a wave of enemies before proceeding: Tip: Before speaking to the shield person, save your game as this is the last possible save point. If you have followed all the necessary steps, no one should have died.
 * someone with biotic power to generate a shield (Pick: Samara/Morinth or Jack. Don't pick: Miranda, Thane or Jacob will cause the death of one of your squad mates.)
 * another person to escort the survivors back to the ship, and you can't use this person for the final session. (Pick: any loyal teammate. Choosing no one results in the death of the survivors.)
 * leader for the second team (Pick: Garrus, Miranda, Jacob. Don't pick: Thane, Grunt, Zaeed, Legion, Tali or Samara.)
 * your team - you will be fighting against Drones, Harbinger, Assassins, waves of Husks and Abominations, and one Scion
 * 1) Drones and Harbingers
 * 2) Husk and Abomination climb up from ledge. Then Drones, Harbinger and Assassins will appear.
 * 3) Husk, Abominations and a Scion.

Final Battle (part 1 of 3):
 * The team you pick here will stay with you for the rest of the suicide mission - you will be fighting against Drones, Harbinger, Assassins, Abominations and Scion.
 * The rest of the team stays back to hold the line until you're done.
 * If you choose the "We'd better hurry." dialogue option, it means that the longer it takes for you to do the end battle, the more of a chance that some of your squad members left behind to hold the line will die.

It's the last part of the game thus it makes perfect sense for it to be hard. You can easily run out of ammo so use your skills well. Basically it's like what happened in the Collector ship. Platforms will fly in carrying several enemies on them. The last platform will contain 3 Abominations and 2 Scions on lower difficulty - good luck with it. There will be a console to trigger the next part (you cannot save here, although there are autosave points).

Final Battle (part 2 of 3):

More fly-in platforms. After clearing each platform, the armor covering the four tubes of the inactive Human-Reaper will open temporarily and you should destroy them immediately (if you're lucky, you can destroy two each round, but this is difficult as their armour covers them very quickly after destroying one). Destroying the four tubes will trigger the option to destroy the facility (Paragon) or keep the facility for Cerberus (Renegade). Then, the final battle starts. If you have the M920 Cain, it is possible to take out two tubes simultaneously, although you may want to save your ammo for the final battle.

Final Battle (part 3 of 3):

You start behind a good barricade spot and you can start shooting at the Reaper's eyes (they are small, but there are 3 of them). It has a nasty charge up attack and it would be wise to not expose yourself until it is done. Once you have damaged the Reaper enough, Collector drones will attack. When the boss' life is below 25%, it will begin dodging around and send more attacks at you (if you are an Infiltrator, your sniper ammo should be your greatest asset at this stage). Keep poking its eyes until it collapses, thus ending the game.

This fight can be ended extremely quickly if you've got good aim and timing. To do this, you'll need the M920 Cain (researched on the Normandy). A successful hit on the Reaper's weak spot (located on its chest) will take a massive chunk out of it, well over 50% of its maximum health. This, combined with sustained assault rifle or heavy pistol fire, will end the battle in under five minutes. Only try this if you have a good aim, however, and dont waste the Cain's ammo before this fight! With the heavy weapons ammunition upgrade maxed out, the Cain can fire two shots; if both shots connect the battle is finished. If the player has the Widowmaker sniper rifle and some type of anti-armor ammo, it does very good damage against the Reaper.
