Underworld Overseer

Underworld Overseer is a virtual reality game in which you play a powerful demon building and managing an underground lair. You design dungeons, summon demonic servants and defend your domain from adventurers who enter it.

Build your dungeon

Command imps to dig tunnels and construct rooms. Rooms attract creatures with different needs and abilities, so you must plan carefully to keep them productive and satisfied while protecting your fortress.

Defend your domain

Turn corridors into dangerous trials by placing traps such as spikes, poison and flames. You can also cast spells including fireballs and lightning, and summon an army of skeletons to attack your enemies.

Levels and challenges

Progress through many levels, each with varied challenges that call for strategy and careful planning.
