Great Multi-player much fun.
Multi-player is fun once you learn the maps. You'll get killed so quick and might not have much fun or even know what's going on at first. Once you learn where people usually camp and run and hide you'll soon be having much fun.
The gun selection isn't the best in my opinion. I'd say the previous games had a way better selection.
I only wish they had multi-player achievements for those who do not play single player.
Most of the maps are fun to play and none of them you'll really hate. Zombie mode is a very fun addition and i know alot of people who dont play shooting games much even playing zombies. It's that fun and a nice change.
Graphics are excellent and the sound is as amazing as all the previous ones. You can't really go wrong buying this game if you're at all interested in shooters.
