So is this any good? Tempted by that price!
It's very fun with friends, has nice combat system which is similar to Gears of War multiplayer where you have to revive your teamates in time or they respawn at latest save point and lose 10% of their cash however if they kill someone within the revive time they can revive and fight on but with about 30% health.
The graphics are pretty good in my view, it has a unique look to it(looks a bit like a 3d comic or so?) plus the engine runs very well except for the few odd memory leaks which people have mentioned though i've only encountered them in a few areas in the General Knoxx expansion.
That said if you like combat fps games with good loot, funny characters and a game with a bit of originality then this is for you.
