Prologue: Earth

Acquisition
You acquire this mission automatically at the beginning of the game.

Walkthrough
After a series of cut-scenes and dialogue with opportunities for morality points you enter the training stage of the prologue.

Anderson gives you an M-3 Predator. Follow Anderson along the ledge following the on-screen prompts. Look below and you will see a child being chased by husks. Go into cover and kill the remaining husks. Use up all your ammo and then learn how to fight in melee. The Reaper ship will burn through the door, go straight ahead to pick up a med-kit. Kill the husks and talk to the child for more morality points in both conversations.

Reload your weapon, and continue along until you get to two alliance soldiers. Kill the Cannibals and talk to the injured soldier. At this point you can allocate squad points for Anderson. Cross the bridge to pick up a second med-kit, and then fight off the next wave of Cannibals. Continue around and pick up the M-8 Avenger right in front of the radio. Activate the radio and fight off a third wave of Cannibals. After you run out of ammo, the Normandy SR-2 will arrive. Board her and say goodbye to Anderson, then embark on your journey to save the galaxy. Admiral Hackett will then send you to your next mission.
