Not bad but does need a patch
As of right now, the winner of every game will be the host (since they would have the best connection). Its impossible to even kill the host right now.
I know the lag issue is a huge con but I'm assuming it will be fixed. The short but sweet campaign mode is actually fun. There's a number of weapons to use which have 3 to 4 upgrades you can get for each (these range from laser sights, acog scopes, silencers, etc). But each upgrade just increases damage, range, and accuracy.
Gamespot really gave it a bad rating expecting it to be Halo or Call of Duty. This is a $10 game we're talking about! Its not supposed to be as polished as those that cost $60. As they say, "you get what you pay for" and that's the case here. A small price for a decent game. Btw, Gamespot..... the term is "lag", not "buggy". The game isn't buggy, it just has lag.
