I would not really call this a game... I would call it an almost pointless simulator... All you can do is basically change the options of what goes on and move around the map and that is it...
Very good game to be honest and quite realistic choices if there was a zombie outbreak. I would give this game a 5 rating. Plus the zombie mmo at deadfrontier.com is pretty good if you get lucky on your character.
Ump+chainsaw=good ak-47+mac=good ak-47+m4a1= okay hunting rifle+ak-47 pretty good
Berret+ak-47=the best/the shit/ hella good
all of these weapon combos are good
