The Epic Games Store has officially revealed its eighth holiday mystery game. The Callisto Protocol is currently free to claim. However, you must act fast. This offer is available for exactly 24 hours and expires today, December 25, at 8 AM PT / 11 AM ET / 5 PM CET / 9 PM Pakistan Standard Time.
This 2022 survival horror experience is the second AAA title featured in the 2025 holiday season giveaway. It follows Hogwarts Legacy, which kicked off the promotion earlier this month.
The Callisto Protocol: A Brief Look
Developed by Striking Distance Studios, The Callisto Protocol is a narrative-driven sci-fi horror game. Notably, it was directed by “Dead Space” creator Glen Schofield. The game recently marked its third anniversary on December 3.
Critics have praised the game’s AAA production qualities and thick atmosphere. Conversely, reviewers criticised the title for technical issues and repetitive combat. Currently, it holds a “Fair” rating on OpenCritic with an average score of 67 and a 41% reviewer recommendation rate.
A Repeat Gift for the Holidays
While this is a high-value offer ($59.99), it is not a store debut. The Callisto Protocol is the first title in this year’s holiday giveaway that Epic has offered for free previously. Specifically, Epic Games Store users could claim this game during a week-long period in late August 2024. If you missed it then, now is your final chance to grab it at a 100% discount.
