If you’ve played the new and insanely difficult survival mode of Left 4 Dead then you’re probably of the same opinion as us and mostly everyone else: Survival doesn’t need a versus mode. Regardless of that, two modders have gone and done it anyway. In the video above you’ll see a demonstration of a mod that allows players to control the special zombies in survival mode. If trying to fend off wave after wave of a increasingly relentless assault wasn’t enough for you then give this a shot. We can almost guarantee that the survivors will never survive, not to mention it doesn’t look to be that much fun for the infected either.
