Just tried the demo:
Multiplayer is damn good not better than COD4 but Ive grown tired of COD4 and this is quite similar with not as good an engine and better graphics.
Im not fond of driving tanks andwhatnot but it adds alot to the gameplay
The shooting system is difficult to master but once you get the hang of it its alot of fun. I pretty much couldnt nail enemies without aiming down the sight and aiming down the sight isnt as quick as COD4, also the gun kind of sprays, be sure to turn the sensitivity down.
Theres much more to this than COD4, theres alot to do, hopefully theres a simple deathmatch option on the full version.
The single player was decent shooting enemies at close quarters is more difficult than it should be, online theres more space and huge maps so you have time to find the enemy but single player its kind of akward but still pretty good. They really messed up the single player by adding the health needle kind of screws things up, I try not to use it untill I find good cover or its kind of cheap. Also if you die they spawn you right were you left off and the enemies you hit still have the same damage
Multiplayer is really good though cod4 fans will have fun taking a break for a while.
