About this game
Monsters' Den: Book of Vengeance is a party-based dungeon crawler with tactical turn-based combat.
Each adventure targets an enemy of humanity, a unique final boss. As you progress through the floors of the dungeon towards your confrontation, you will battle enemies from diverse factions, collect loot and make choices on how to resolve encounters within the dungeon. Build the synergies between your team's skills and equipment to enact final vengeance. Success means unlocking new campaigns and new skill trees to try in your next adventure. If you've grown attached to your party, continue to play and optimise them in the infinite mode.
Taking inspiration from the fan-favourite Book of Dread, the Monsters' Den series returns to its old-school roots in this all-new title.
Unique skill system. Combine skill trees to create hybrid skills. Master more than 100 distinct class combinations and thousands of skill possibilities.
Hunt for vengeance. More campaigns and unique bosses than ever before.
Dynamic dungeons. Encounters can be resolved in multiple ways. Avoid alerting your enemies.. or choose to go loud.
Comprehensive custom portrait support. Use your own character art-- even for the monsters.
