Oh yes, also:
...shooter with a Story...
It doesn't have a story. It's a bunch of short sidequests thrown together and you complete one at a time. There's one main quest which is unlocked as you complete some number of these other sidequests (which don't affect the main one, by the way) and then the game forces you to complete the first two portions of the main quest. The last part you can start whenever you want after it gets unlocked though, so that you can finish all sidequests before finishing the game.
There's nothing else to it though. You complete quests, gain the "loyalty" of your team members and then embark into a 30 ~ 40 minutes long final quest which consists of you shooting everything that moves and making a single choice at its end which doesn't seem to have any effect at all, specially now that we know Cerberus will turn against you in ME3.
