Transformice Adventures will see players take on the role of brave mice and battle various animal enemies in a four-player cooperative dungeon crawler. Combining rogue-lite game mechanics with expansive online social experience, the new action adventure RPG allows players to enter challenging dungeons and do combat with unique enchantments called Elisah’s Gifts that alter the mice’s skills and weapons. They can also customise their playstyle in Transformice Adventures by choosing different skill-sets and unusual jobs, from journalists to botanists, and take care of their own personal pets who can join and help them in their quests. At the end of the day, players can retire to the local tavern to chat with their friends, and show off their best outfits.

Transformice Adventures is the successor to Transformice, the massively multiplayer platformer game about mice gathering cheese, which was released in May 2010. Seeing monthly updates, the popular MMO has grown tremendously, passing a landmark 100 million registered accounts on its 9th anniversary in May 2019.
