I love this game, its so much fun.
Ive just spent the last hour or more killing zombies in so many different ways Ive literally laughed out loud.
The hazmat zombies are hilarious, get them in a group and whack the gas tank on their backs, blows them all to peices. The explosion draws attention so quickly climb to a high roof top building and wait a mo for the running zombies to chase you up there, as theyre climbing to the top, kick them off.
The melee combat is so fluid, when youre swinging a metal pipe around and it catches a zombie right in the face it looks brutal, the variation of swings, hits, falls, tumbles, counter attacks etc is great. I particulary like the grapple move and pushing them off a ledge but if you can time it right its so satisfying to burst a gas cylinder and then push a zombie into it, it explodes and they fly backwards. Best zombie game to date imo, it beats Dead Island hands down.
Gonna play some more!
EDIT: Been playing all evening with no crashes at all, it seems the patch has fixed some things. Im getting good fps with SLI 980's at 3200x1800 res, everything on max with AA disabled ingame but got FXAA running in Nvidia Inspector. The only gripe at the mo is the flickering blood splatters on the screen which seems to be an SLI issue but Id rather put up with that than the fps drop from disabling SLI.
