I didn't play much of the single player campaign, but the multiplayer in this game is some of the greatest gaming ever.
I love the choice of weapons, with a gun for every situation. ( you can customize them! )
The one thing that stood out about this game was the addictive gameplay, although some online matches are VERY difficult.
I found myself getting frustrated alot first starting off, so we played some of the "Special Ops" missions, although i didn't play too much of the actual campaign. Each Special Op mission is action-filled and exciting! if you like FPS games this ones a must have! I've played it the 360 as well, but i definitely prefer the PS3 version.
Sick!
