super awesome. 2 things though:
when you try to change to another weapon while aiming, you cant do anything other than move around. also wish that there be some form of bullet force so zombies don't just fall over like they just tripped (imagine a zombie flying off when being point-blanked by a shotgun lol.) other than this its awesome, even got spooked a tad when the zombies started to yell and run towards me.
