Ah, who am I kidding. You play as Kaidan Alenko, a turian, who is fighting against the geth, led by a salarian called Captain Anderson, who is trying to bring back an evil destructive race called the Elcor. Your main squadmates are Saren Arterius and Commander Shepard, as well as the Turian councillor, Ambassador Udina and Blasto, a hanar spectre. In the second game you recruit a team to take down another vanguard of the Elcor called the Volus, who breathe fire and eat babies. You recrcuit characters such as Blasto from the first game, an asari spectre named The Illusive Man, Commander Shepard, a Reaper called Harbinger and a biotic called Niftu Cal, who, if you recruit him, means you automatically win the game due to his immense biotic-god-ness. Seriously, I don't know what everyone else is on about.
