Blind zombies would be nice but we would have to limit the number as 20 noobs going "cool i can fling shit into human eyes" would get very, very annoying. Smoker-like zombie perhaps but only with a 5 foot range to pull noobs in? Can we do that without glitching props?

Or to challenge yourself, either a completely shit zombie, or a chameleon-like zombie with different stats at each round start.
