I have to say the game just kicks ass. Especially with 4 players. Only complaint I have is there is just not enough weapoins. I want more weapons in the game. Alien weapons are not all that sweet. And I hate that you can\'t hold more than 2 weapons.
But the levels are just huge. It is defenitly an xbox killer app.
I got it monday and have been playing it none stop with friends. I am nearly at the end of the game.
