This must be one of the most creative StarCraft II mods out there. Fast-paced ice hockey with StarCraft characters and abilities, made entirely with the game's map editor.
The creator of this mod, Leeroy, made the rules simple but fun: Each team has four players, three Zealots and an Immortal goaltender. Shoot the puck past the goaltender to score and don't let it use its force field. See it in action in the clip below:
