However, you must go through a lot of trials as aliens called Geth are on the attack and another Spectre agent named Saren has gone rogue. He is trying to become the first human Spetre in a strange and vast intergalactic government system. The story has you as Shepard, who has a default look to him or you can make him or her to your tastes. It is a role playing game through parts of it and a Gears of War shooter as well.
This game was not quite what I was expecting and was for the most part a lot of fun.
