Check out this trailer for the recently greenlit Steam game, Crawl. It's brutal, but in a old school kind of way.
Crawl is described by developer Powerhoof as a "competitive multiplayer dungeon crawler" in which 1 player plays the hero and up to three friends play the monsters and all on the same screen. If a monster kills the hero, that player becomes the hero and you start dungeon crawling. Online multiplayer is will not be available up front but Powerhoof is "exploring" the possibility.
No specific release date has been shown but the developer is shooting for the first half of 2014 on PC, Mac, and Linux. Does Crawl interest you? Let us know below.
