Crysis 2's multiplayer was pretty fun, easy to play and kind of addicting at first. Some people thought the suit makes you overpowered and so the whole mutliplayer aspect of the game is therefore unfair an flawed but that's not true. Everyone has the same suit it's all on your and how you plkay, theres upgrades on your weapons as you level up and even killstreaks. I'll say this, I enjoyed it more than the last few CoD's so there you go, definitely worth a try. Singleplayer on both games are spot on too.
