Something to improve
I loved that game, but there is one thing to fix :
you should be able to switch gun while reloading. For instance I just shot a bunch of zombie and I need to reload, but then this fast running guy comes out of nowhere and start destroying my base ! I can't do a thing because I'm still reloading.
I should be able to stop reloading that and grab another gun to kill that guy !
Great game though
