In a move that’s either incredibly ironic or just plain dark, Epic Games has chosen The Callisto Protocol as the mystery gift for December 24. While most people are settling in for festive cheer, Epic is sending us to a high-security prison colony on Jupiter’s dead moon to fight mutated horrors.
If this feels familiar, it’s because the game was previously offered for free back in August 2024. However, if you missed that window or were skeptical about the launch reviews, now is the perfect time to grab this AAA survival horror experience without spending a dime.
The Spiritual Successor to Dead Space
Directed by Glen Schofield—the man who co-created the original Dead Space—this game was built to be the next evolution of sci-fi horror. You play as Jacob Lee, an inmate at Black Iron Prison who finds himself in the middle of a gruesome outbreak. The UI is integrated directly into the world (your health bar is a glowing implant on your neck), keeping the screen clean and the tension high.
Brutal, Up-Close Combat
Unlike many horror shooters where you keep your distance, The Callisto Protocol forces you to get personal. The combat system leans heavily on a rhythmic dodging mechanic and a powerful electrified baton. You’ll spend as much time parrying and bashing limbs in melee as you will firing your weapons.
The “GRP” gravity tool is the real star of the show. It allows you to pick up enemies and launch them into environmental hazards like spinning fans, wall spikes, or even off ledges. It adds a tactical layer to the encounters, making the gore feel almost like a puzzle.
A Technical Powerhouse
Say what you will about the gameplay pacing, but the visuals are undeniably some of the best in the genre. The lighting, character models (starring Josh Duhamel), and sound design are top-tier. It captures that oppressive, claustrophobic atmosphere perfectly, making the “holiday” setting of a derelict space prison feel genuinely unsettling.
Claim It Before the Big One
The Callisto Protocol is free until December 25 at 11:00 AM ET. Since tomorrow is the actual Christmas Day reveal, the community is expecting a massive title to close out the holiday peak. Don’t let the gore distract you—make sure you add this to your library before the mystery counter hits zero.
