With MW3 being a total disappointment i came back to Crysis 2 MP, but yesterday after 30min of multiplayer i remember why i left: the attachment unlocks missing, the host advantage, the incoherent killcams, the weapon lock in middle of combat, the random suit energy loss, the maps that i bought but i can't play, the hackers, dedication achievement, ETC. the list is pretty much endless, and yes THESE ARE GAME BREAKING ISSUES...
don't waste your time with this game, if Crytek and EA doesn't give a crap about it why would you?
if you agree with this, the best thing we can do is NEVER pay again for a game made by Crytek or made with his engine (like sniper ghost warrior 2).
