i have get my copy this morning and had some time to play.
the gameplay is just lovely, finally a game where campers and bunnyhoppers are not doing great
its a fast gameplay and the level building is almost perfect for this gameplay

Why: my first hour i have kill atleast 30 campers and have see bunnyhoppers die like bunnys
this game needs moving and teamplay so if you camp you will die very fast, and its lovely

so i have a feeling that the complaining people are the cod camper kids that now get killed like crazy
and coming here to flame the game

Some machine guns seem underpowered, that's the only thing I've noticed. But it would be nice to be able to use the mouse to pan around when you're capturing or building an objective instead of the keys. Hope that's possible to implement.
