Epic Games has revealed that The Callisto Protocol is the free game of the day for December 24, 2025. This 2022 survival horror title from Krafton is available to claim for 24 hours as part of the store’s annual Christmas daily giveaway. If you add the game to your library before 11:00 AM ET on December 25, it is yours to keep forever. This daily promotion has become a holiday tradition for PC gamers, offering a wide variety of high-profile titles leading up to the end of the year.

Stunning Visuals and Atmosphere

The Callisto Protocol is well known for its exceptional graphics and intense atmospheric horror. Set on Jupiter’s moon, Callisto, players take on the role of Jacob Lee as he tries to survive a terrifying outbreak in a maximum security prison. Even three years after its initial launch, the game remains one of the most visually impressive titles available, featuring highly realistic character models and detailed environmental effects. For fans of audiovisual spectacles, it provides a high-fidelity horror experience that pushes modern PC hardware.

Spiritual Successor to Dead Space

The game was led by Glen Schofield, the creative director behind the original Dead Space series. While it features a unique melee-focused combat system and a different approach to scares, it shares a similar sci-fi horror DNA with its predecessor. Though it faced high expectations at launch, it has found a dedicated following for its brutal combat and cinematic storytelling. Now that it is available for free, it is the perfect opportunity for horror fans to experience the game for themselves without any cost.
