The Epic Games Store has revealed its latest free mystery game, and it is Eternights. The game is available to claim for free until 11 a.m. EST on December 20.
Eternights is developed by Studio Sai and offers a mix of different gameplay styles. It combines dating simulation elements with fast paced hack and slash combat. The game is set in an apocalyptic world where humans have turned into dangerous monsters. Players explore dungeons, fight enemies, and also spend time building relationships.
One of the unique parts of Eternights is its anime inspired visual style. The game lets you balance action packed combat with lighter moments, such as going on dates and forming bonds. It tries to add a human touch to a world filled with chaos and destruction.
Epic usually reveals its free games in advance, but things change during the holiday season. Instead of showing the game name, Epic hides it behind a mystery gift image on the store. Each free game stays available for only 24 hours, which adds to the excitement.
To claim Eternights, all you need to do is log in to your Epic Games Store account and add the game to your library. Once claimed, it is yours to keep forever.
The mystery game lineup for December 2025 has already started. On December 18, Epic gave away Jotunnslayer: Hordes of Hel. A new mystery game will unlock every day at 11 a.m. EST, so players should keep checking the store daily.
