So I've been playing this for a couple days now, and I'm very pleased. It's halo in all its glory. The prometheans are less intimadating than the flood, but I felt to at home in this game that ut didn't matter. The new controls sadden me, but they're doable so I don't whine. The amount of weapons, the new enemies, the new vehicles, and the overall feel is so awesome...I love this game.
I recommend playing this on legendary with pals and never look back.
