Spooky Halloween incoming! What's the best way to celebrate it if not slaughtering hundreds of Zombies in the Underworld?
Underworld is a reskinned version of the awesome Underground map, a well known masterpiece of the Iron Gauntlet assets. Both Underground and Underworld made by the same author, Woozles.
