I wasn't thinking that the ranged zombie idea should do any damage like at all but as i mentioned an ability like blind or have a grenade that can "push" people around and do no damage whatsoever. And as for the Tank Zombie I think deformed already covers that pretty well :| just that people don't seem to use it as often as some. But yeah I think power zombie should still be in the top for consideration
-- And I do like the spy zombie concept - maybe it has the least hp possible like 200-100? and if he/she tags a human the human becomes the new spy zombie and the previous spy zombie becomes a human again? I don't know haha still throwing ideas at you guys!
