Aiming to release this year
The old Gauntlet games are some of the best cooperative experiences of days gone by. There was something about destroying monsters with your buddies, leveling up your character, and competing for loot that made those games special.
Hammerwatch is a hack-and-slash dungeon crawler that is currently hanging out on Steam Greenlight. It's inspired by Gauntlet, though I cannot confirm whether or not anyone needs food badly. It's definitely worth checking out as it will include modding tools to extend the game's life indefinitely, online and local co-op, a hardcore mode, and it is coming to Windows, Mac, and Linux.
Remember, if you like it, give it a vote on the Greenlight page!
