Dungeon Overlord will be getting a new update called The Succubus Stories. The update will expand the story and increase the replay value of the game with repeatable quests that emphasize endgame PvP content. On top of that, mobile apps will also be launched shortly. I never had the chance to get to the endgame PvP content, but I've also never been good at PvP, so maybe it was for the best.
