- Zombies can pass through any door, walls, fences, stacks of hay, sometimes cars, and other inanimate objects with any type of collision or knockback.
- Zombies do not react to the momentum from getting hit by any objects (like a baseball bat). Hitting them from the front, side, or rear won't show proper animation to reflection the motion/direction as a result from a hit.
- Zombies colliding with other zombies don't seem to happen quite well. They just seem to stop near eachother, but not actually push eachother or knock them back (or forth if another zombie jumps on their back)
- Blood splashes only from one area when hitting zombies from any side or angle.
