ZOMG i luvv this game. The co-op is epic and the campaign scenario and weapons are well thought out. Tanks are so ftw. also i like boomers (teh ones that shoot [cabbages ftw] out their mouth at you). this game definetly rivals the best games for xbox (which are as follows): CoD 4 Bioshock Fallout 3 Halo 3 Left 4 dead etc.
