PC gamers are no doubt familiar with the Epic Games Store and its practice of giving away games for free. Typically, the Epic Games Store rotates its free titles on a weekly basis, with one game on offer every 7 days. But during the holiday season, the free deals are on a more aggressive pace, with a new one revealed every 24 hours. That means gamers have more free games to grab, but less time to get them. The latest free game has been revealed and will be available to claim from 11 AM ET on December 24th to 11 AM ET on December 25th. Fans of sci-fi, horror, and shooters will want to make time to claim this one.

The Epic Games Store free game for December 24th is The Callisto Protocol from Striking Distance Studios and Krafton, Inc. Players who log in and claim the free game before this deal expires on December 25th will have access to The Callisto Protocol for good. So even if you won’t be playing on Christmas day, it’s worth grabbing it for when you will have time. If you’ve not heard of this one, let’s dig into the details to see whether you need to make haste to snag The Callisto Protocol while it’s available for $0.
Is The Callisto Protocol Worth Grabbing While It’s Free?

The Callisto Protocol came out in 2022, bringing players a narrative-driven third-person survival horror game with shooter elements. Set in a futuristic landscape, players must escape Black Iron Prison, a maximum security facility on one of Jupiter’s moons. The only problem? Your fellow inmates have begun transforming into monstrous creatures, so you’ll have to battle your way out.
Reviews for The Callisto Protocol are admittedly pretty mixed. At launch, it earned a 69 Metacritic Rating, and retains a Mixed Review average on Steam for PC players. In particular, players wanted to see more variety in combat and enemies. That said, many say the game is flawed but still engaging, with fun exploration, solid graphics, and some tense story moments. For the price of free on the Epic Games Store, it’s definitely worth checking out if you’re a fan of survival horror and sci-fi games.
