The utter lack of polish and adding in too many mechanics while not tightening up the core gameplay. They also did not have a versus mode where you could control the zombies while the survivors made their way through the map, which was in my opinion one of the most fun versus modes in any game.

Yeah, I had a lot of fun with it. I didn’t like the zombies vs humans mode and prefer the l4d way, but the campaigns were really fun.
