Your friends control the monsters in Cormanesque horror game Crawl

Crawl looks like a fun action RPG in a Victorian horror setting. The gimmick: your friends control the enemies! They have a Steam release date of "first half 2014."

One player controls the Hero, the others possess monsters and traps to kill them. Destroy the hero and it’s your turn to crawl as you instantly take their place. Race to gain enough XP and loot to challenge the dungeon’s boss, cooperatively controlled by the other players!
