Campaign sucks - glitches, checkpoints, getting sniped by shotguns, AI ALWAYS knows where I am at, inconsistent deaths... sometimes I'm Rambo and sometimes I'm glass, and very weak story plot.
Campaign is 7/10 with only graphics giving it that 7.
Multiplayer? I don't know... I can't play due to many connection issues. EA once again dropped the ball and brag about how much money they are making. Shows that their loyalty is to our wallets and not for our entertainment and giving customer support.
What I have played all I can think of is 'If it isn't broken, don't change it.' They slaughtered BF2 and those familiar with BC2. Its CoD on a larger scale and instead of killstreaks you have vehicles.
