Bug - managed to shoot a grenade at the spawn point on 2 player deathmatch, killed both of them....and then it proceeded to kill another 100 odd of them as they spawned...(total kills for that round didn't go up by that, but did get the cash for them)
Fairly fun and straightforward game, might be good to have some sort of a story to it as well, so that there's a clear progression, rather than just being repetitive.
