Navigate dungeons and fight your way through hordes of creatures in this Role Playing Game (RPG). Deadly Dungeons is an RPG developed exclusively for the Android platform. This RPG is influenced in part by classic dungeon crawler games such as Dungeon Hack, Eye of the Beholder, and Nethack.
After being separated from your adventuring party, you must navigate a deadly dungeon, and fight your way through hordes of creatures in a desperate attempt to escape alive. What first begins as a simple escape to the surface turns into a fight for survival, a confrontation with an ancient evil, and a descent to hell itself.
