Amazing
The online mode is very fun, although i do wish there were more modes.
Playing co-op over live is probably one of the best experiences I've ever had with any video game. Hope Halo 3 follows.
The guns feel very well balanced and movement trough the environment feels very realistic.
The cover system is alsom very well thought out and works spectaculary with the level design of the game.
Can't wait to go play again! Can't wait for a sequel!
