Tiny Plumbers creator Robot Loves Kitty teases its upcoming "co-op roguelike beat-'em-up" Legend of Dungeon in the newly released trailer above.

Legend of Dungeon is a side-scrolling action title in which up to four players compete to kill monsters and gather treasures scattered throughout each floor. If you're interested in keeping track of the game's current state, Robot Loves Kitty has set up a blog chronicling its development.

Legend of Dungeon will premiere as a downloadable title for Windows, Mac, and Linux. A release date has not been announced.
