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!
Leave the throne room to enter the Overworld - you can find more Dungeons there, and learn more about them BEFORE you enter. Useful for preparations!
