Dungeon Deities is part Browser-game, part realtime Dungeon Crawler. Players traverse the Dungeons of other players, carefully avoiding traps and battling enemies in search for treasures, which they can then steal. Naturally, you store your loot in your own dungeons, so make sure they are safe!
If you manage to reach and open the golden chest, you beat the dungeon. In there, you may find something very valuable - such as the orb someone else is currently using.
