I have played Campaign and haven't finished yet, I'm at the dam, and I've also played Multiplayer and I've had tons of fun on both MP and SP!

I guess because I've been using the Typhoon gun and it kicks butt! but Still , There's no rules on which weapon you gotta use to play with =)

But its a very fun, colourful and well made game for me! =D,

The only problem I had at first is I had a crash where I had to reinstall Crysis 3 and then after that was solved I played a part in the campaign where I fell thru the ground and continued to fall but I fixed that right away.
