Awesome!
This is a brilliant game, absolute genius.
And looking at some reviews, it appears that the majority of complaints can be fixed by sending people to play the tutorial, which is always a good sign. However, I do beleive the AI needs to be upped. Not the zombie AI, they are pretty convincingly zombie-like, seeing as how they are meant to be stupid. However, the survivor AI appears to be incredibly stupid. For example, in the middle of a zombie horde, zombies broke through my lines in one zone. What do the civilians do? Run into a dead end and get eaten. Thirty survivors dead in about ten seconds.
