Missions

Missions are quests which advance the main storyline in Mass Effect. The list contains all of the missions available within the game, and indicates how their names will change as the story progresses. Click on the links below for detailed walkthroughs.

Note: Most mission names below are linked to the relevant section of the walkthrough rather than their own pages. Because of the intertwined nature of most missions, the link may not lead to a section specifically about the mission name but you will certainly find relevant information.

For an alphabetical list of missions see Category:Missions; for locations see Category:Mission Locations.
