Overview

Mulligan Keep invites players into a cooperative deck-building dungeon crawler experience, where up to four adventurers can team up to explore a mysterious mage's castle. The core gameplay revolves around strategic card play to overcome obstacles, evade monsters, and disarm traps as you progress towards a hidden artifact. However, time is of the essence; the longer you take and the more noise you make, the more the dungeon itself begins to crumble around you, adding a dynamic layer of urgency to each expedition.

Highlights
