Well, I plugged this comic last time, but I'll do it again. http://www.thezombiehunters.com/zombies.php Keep in mind that this comic had been here for years before L4D came out. There are only 3 zombie types from there that they haven't already stolen. The Mercy, which is a pacifist zombie. The Berzerker, which is basically just a compact sized Tank that likes to play with it's food. And the Basilisk.
This one would be cool. It looks like a normal zombie except for red, glowing eyes. When it gets close enough to a survivor and locks eyes, they have a seizure and collapse, causing minor damage, incapacitating that survivor until they are helped up by someone else. The seizure makes the survivor spray bullets wildly around them, possibly injuring the other survivors.
