Great game, though I feel like the characters definitely could've been more fleshed out, I really only remember George, Kat, and the edgy skull helmet guy. The ending was pretty awesome though. As far as the multiplayer goes, all the great social features from 3 are back, although this time we also got Firefight, which is one of my favorite modes to play with friends. The customization system also felt just about perfect in Reach, especially with how your custom armor set shows up in the Campaign as the protagonist. Bloom is kinda dumb though.
