Defeating the Kett

This is the final mission for the planet Eos. The kett stronghold on Eos is a power station in the western part of Eos. Dealing with the station will greatly improve the viability on Eos.

Acquisition
The mission auto-starts when Ryder get close to the base.

Walkthrough
Ryder has to disable that glowing blue shied and eliminate all kett inside. Saves are disabled, and there are only a few auto-saves, thus getting defeated will often require you to redo a large portion of the fighting. It is easy to get overwelmed by ongoing waves of kett reinforcements.

Investigate the kett presence
Fight your way to the map marker far inside the facility. On the way other objectives will be revelead. The objective will complete when you reach its map marker, and the objective "Override the security terminals" will start.

Find a way inside the kett power facility
For at start Ryder has eliminate the kett and the two turrets protecting the entrance.

Unlock the shield gate
Interact with the Locked Console. Then defend your position and eliminate the attacking kett while staying close to the console. Now Ryder can enter the facility through two doors.

Access the stronghold core
A long walk and many fights is required to reach the core of the stronghold without any auto-saves.

The facility ahead of you has three main sections: Kett Shield Station, in the far end is the Base, and underground below the Base is the Core with the Command Center. The Kett Shield Station is the large ring-shaped construction, and beyond that is the Base.

Immediately on the other side of the two doors you enters the Kett Shield Station, and more kett forces has to be defeated.

Optional: Access the kett shield arrary. To shut down the blue shield three consoles has to be accessed. Using the first one gains access to the shield array (marked on map).

Optional: Set the shield generators to overload (0/2). The other two consoles are further inside on the left and right sides (marked on map). Use them to do some sabotage. This can be done without getting attacked.

Optional: Overload the kett shield array. Go back to the first console and jump up on the top of the building. Use the console there. SAM informs you that the alarms have been disabled. Now Ryder can use the other console on the roof to deacivate the shield.

Beyond the inner end of the ring-shaped construct are the Base section of the stronghold. Kett defenders there are waiting for you.

Important: From here on you need to stay alive until all the kett and the boss have been eliminated. If are defeated you will have to redo everthing frpom this point.

SAM will inform you that reinforcements will arrive soon, and an alarm starts sounding. You better to shut down the alarm because reinforcements will arrive in waves as long as the alarm is on. Find an alarm console to deactivate it (no map marker; any alarm console will do). This will happen occasionally when you are fighting your way though the base.

Override the security terminals
Three security terminals are marked on the map. Deactivate them. Occasionally an alarm will start to call in more reinforcements. Find an alarm console to deactivate the alarm. Oddly, the map markers remains even after all of the security terminals have been deactivated.

Enter the room in the rear end of the sstronghold and find the console that will open the floor-door to the core of the facility. Opening it complets the objective "Access the stronghold core".

Reach the command center
Down through the hole is the command center with two groups of kett and the Kett Invictor (the boss).

Jump down.

WARNING: It's possible to jump up again, but if you do the boss might not show up. Whether its by design or a bug is unknown. In that case you have to reload the last save, which is when you first enteredthe Base section.

Eliminate the first group of kett.

Open one of the three doors to the next room room. In there is the boss and his adds. Its a good idea to eliminate the adds first so you can concentrate on boss without risking being attacked from behind or get into cross-fire.

Eliminate the kett Invictor
His is surrounded by an impenetrable shield. Around it an orb is circling. Destroy the orb, and the shield will dissapear for a couple of seconds. During that time he takes damage. Then he puts up the shield again. Patiently grind him down. Occasionally he sends out an expanding orb of damage. Don't get caught in it. When you see him charging it, move to the side and hide behind som big object. Don't get close to him - he can kill you quickly - fight him from range.

If you are defeated you have to reload the latest save which happened a long time ago, so it's more important to play it safe and stay alive rather than attempting a risky quick-kill.

Unlock access to the zenith observation rooom
Use the console to do this.

Access the zenith observation room
Pass through two doors and use the elevator.

Disable the power facility
Use the console. THis completes the mission.

Loot the five container before leaving the room. Use the elevator.

Note: If you wish to fast travel from the facility, note that the map has three levels (lower right corner). The surface of Eos is the bottom one (click it). This is mentioned here because this might be the first time in the game you encounter this.
