I think that it would be cool if you were able to be killed as a player (if it were death by zombies, or if you were diseased) and you were to resurrect (upon choice) as a zombie. You then would have a chance to kill players, being that you would be super fast, and possess slightly higher damage coeffecients than zombies. So lets say a zombie inflicts 500 blood dmg per hit: A player zombie should then inflict 1000 blood dmg per hit, and should be able to run just as quickly as the other zombies. I also think that it would be fair if the player zombie had the same effective health pool as other zombies in the game, making you just as easy to kill. There should be no difference in skin (you should spawn up with a NPC zombie skin) so that you are better able to blend in with masses of zombies. Lastly, you should be able to influence the behavior of other zombie NPCs in the area. If you are sprinting as a zombie player, their zombie NPCs around you should follow your path at the same pace, allowing you to pursue a player without then being singled out once away from a herd. Any thoughts fellow survivors?
