Very good game with outstanding multiplayer, but the single player game is too short.
But as you've probably heard the games largest floor is that the single player game is very short. I think I managed to finish it in a week or so of playing a few hours a day. But the game makes up for that by the best multiplayer that I've ever played. in multiplayer your character sadly cannot be customized but that isn't too bad. You progress levels easily and quickly but they get harder as you go on. I managed to level up after my first kill but now it takes me days to level up. As you gain levels you unlock weapons and special abilities. There is a wide variety of weapons and you can also equip abilities ranging from higher health to an RPG or C4's. There are lots of people playing online so you're never short of a game, but beware it may take a while to find one at first.
So in all an excellent game, defiantly worth buying. A short story is the only major problem with the game. But thanks to multiplayer you don't feel robbed.
