I am contemplating buying some of the downloadable content for Mass Effect 2 on Xbox 360. I am currently early/mid game and want to try and get some of the recruits and extra missions that make sense to do before pushing on to the end game areas. However I see there is a lot of DLC for the game.
My question is, what packs are the mission ones and ones that have achievments tied to them? I had bought the game new so I have the Cerberus Network but I am unsure as to what packs do what.
Any help will be appriciated but please avoid spoiler posting.
