Hi,
I think I understand this more, I did get past 3 levels, and it seems the fun is in watching the zombies, which are yours beat down doors and or attack people that you target, Once targeted, you manuever into a good watching spot then hit the z button for slo mo if you like. The resulting ragdoll sequences are indeed interesting.
I did get stuck on the fifth level though.. I like the diversity of characters.and weapons!
Can you add brains flying to the head splats??
Fun Stuff..
