The civilian saving concept is quite nice. But please make the civilians a bit smarter! Like if they are scared of the zombies (which would seem logical). At the moment they seem to enjoy beeing turned into a zombie, which is fine by me, but not when it makes me lose the game.

It however, took me a while to figure what were zombies and what were the civies. Especially because the briefing screen displayed just one version of each while the game had many more. The use of colors is a bit strange. I expected a distinct difference between the zombies and civilians. After losing a third game, I just started shooting everything that did not look like the one civilian displayed in the briefing screen.

Overall a nice game, but with a few simple adjustments it can even be better.
