Crawl Key

Crawl is a local multiplayer dungeon crawler where your friends control the monsters.
It's a combination of bullet-hell beat-em-up and old school RPG in an arcade party game for up to 4 players.

One player is the hero, exploring a randomly generated dungeon, full of traps and monsters, all controlled by the other players.
If you kill the hero, you take his place and it's your turn to crawl! Then there is a race to gain enough XP and loot to reach the final battle, where everything is on one, the other players collectively controlling the huge final boss.
