- Zombies should not pass through walls, floors, fences, and gates. They're not ghosts, they're mindless undead humans corpses.
- Now that many many more have been added, wasn't the sheer number enough? Why are they now also champion sprinters, able to lunge 50' in half a second, and do more damage (much more damage).
- Zombies are supposed to be pretty easy to avoid. They should respect the sanctity of things like walls and fences because if they did, this game would still be playable. We should be able to lock them in buildings and generally outsmart them as opposed to constantly running for our lives.
- If zombies are characterized in a game, have respect for what a zombie is.
