Not bad.
This game is pretty good, although it is a little simple. I think that every 30 seconds or minute, a round should end, where you could upgrade your character with better armor, weapons, etc. As for other reviews, of course all you do is run around and survive. Ever play Contra? Zelda? Halo? All you do is kill enemies and survive. Your teammates DO help you. Notice that there are a lot more Russians than Germans? Decent game.
