Just a thought on my part. If you are going to go with completely unrealistic zombies. You might as well just go for the most outrageous one of them all, and that would probably be the hive mind from Dead Space. Nothing trumps bigger then an office building, or being able to drive others insane through mere proximity. I am kind of surprised that nobody brought this up.
Personally I don't consider any of the things listed previously to be zombies. I think developers take too many liberties with the concept, and slap the moniker on what should really be referred to as monsters or mutations. The best good concept I have seen in quite some time has to be the Infected from Dead Island. They are just basically your standard zombie that screams and runs real fast at your character. It is a good game changer, but it doesn't come off as seeming to be ridiculous.
