lol just make em the same look as ur reg.zombies but throw on some a different color of defining spot, there its less work to create, therefor ez for every1, and then u can add like 1 or 2 specaility zombies, they have to look different then therest, other wise the players like me would shun the game and move to another, maybe ... have thier powers like cloak, ability to fire, ... the choices r endless, hell then u might as well thrrow in a zombies that r aready on fire and when hit leave an 3-20 afterburn depening on level or place, or however u set up the difficulty
