OK, I don't like being the lone stick in the mud, but I thought the multiplayer was absolutely horrible as far as gameplay went. Visually it's great... but it's Counterstrike. If you were to blindfold me and sit me in front of a PC running it, my first impression would've been that this was a CS:S mod. The points system is totally bolted on - points are stored locally, not on a server. So if I play from my laptop or from my desktop with the same account, my points will be different.
Now all that alone isn't the end of the world. For me, the worst thing about it was that there is no way to form distinguishable squads. The action is so chaotic - which sometimes is a good thing but it's like that on ALL maps - that if you're trying to play with friends on teamspeak, it's virtually impossible to keep track of them, where they are, what they're doing, etc. If I could just make them a different color in the minimap, I'd be happy.
My final gripe is the balance of the game. The weapon unlocks give the guys that play seven hours a day SO much more of an advantage that it's ridiculous. If you're on a map with an M16 - or even the M4 or MP5, and the rest of the guys on the map have P90's, you might as well leave the server because your kill:death ratio is going to end up being around 1:10.
Like I said, I hate to be a stick in the mud since we're having a big CoD4 love-in here, but I feel like I wasted my $50 on a single player game that lasts 6 hours, and a multiplayer game that's unoriginal and unbalanced.
But hey... it IS pretty, you can't argue with that.
