About The Callisto Protocol:
Set three centuries into the future, the story unfolds within the cold, unforgiving confines of Black Iron Prison, a high-security facility nestled on the desolate moon of Callisto, where the player steps into the role of Jacob Lee, an unfortunate prisoner trapped in a nightmare beyond comprehension. What begins as mere confinement quickly spirals into unrelenting terror when the inmates undergo horrifying transformations into grotesque abominations, plunging the prison into violent anarchy. Amid the chaos, survival becomes a desperate pursuit as Jacob struggles to navigate the collapsing corridors and unravel the sinister mysteries buried deep beneath the moon’s icy surface. Armed with a combination of firearms and brutal melee techniques, he must rely on cunning, adaptability, and resourcefulness to overcome the relentless horrors that stalk him. Every encounter demands calculated precision, forcing players to scavenge supplies, upgrade their weapons, and master new abilities in order to endure the escalating threat. The suffocating atmosphere, coupled with the eerie silence of Jupiter’s shadow, amplifies the tension as each revelation peels back another layer of the prison’s dark experiments and the truth behind the infection. Through its immersive storytelling and visceral combat, the experience captures a haunting balance of fear and determination, transforming each moment into a fight not just for freedom, but for survival against the inevitable horrors of a dying world.
Played entirely from a tense third-person perspective, the experience places players in control of Jacob Lee as he fights to survive within the nightmarish confines of Black Iron Prison, where every encounter demands precision, timing, and nerve. Jacob’s physical condition is monitored through a neural implant known as the C.O.R.E. Device, embedded visibly at the back of his neck, serving as a constant reminder of his fragile mortality. To restore health, he relies on scarce injectable packs scattered across the desolate corridors, forcing careful exploration and resource management. Combat blends raw brutality with tactical depth, allowing seamless transitions between firearms and close-quarters melee strikes, where dodging, countering, and exploiting openings become essential to survival. Every confrontation tests adaptability, requiring players to anticipate enemy patterns and combine both combat styles to create fluid, deadly exchanges that vary depending on the threat. Enemies exhibit disturbing resilience, refusing to fall even after suffering massive head damage, which demands that Jacob strategically target limbs and exposed tentacles before they can mutate into stronger forms. Through exploration, players can uncover audio logs that deepen the grim lore of the prison and reveal chilling details about the experiments conducted within. Each encounter and discovery heightens the oppressive atmosphere, turning every corridor and shadow into a test of endurance and instinct, where mastering both precision and aggression becomes the only path to escape the horrors that await.

Released in late 2022, this grim and atmospheric survival horror experience emerged from the creative vision of Striking Distance Studios under the direction of Glen Schofield, the acclaimed mind behind the Dead Space series, establishing itself as a chilling spiritual successor to that legacy. Available across major platforms including PlayStation, Xbox, and PC, it immerses players in a nightmarish descent into terror set on the icy surface of Jupiter’s moon, where despair and mutation intertwine. The narrative follows Jacob Lee, a starship pilot whose routine cargo mission ends in catastrophe when he crashes on Callisto and is unjustly thrown into the heavily fortified Black Iron Prison. What begins as captivity soon devolves into a desperate struggle for survival when a horrific outbreak transforms inmates and guards alike into grotesque monstrosities. As Jacob searches for a way to escape, he uncovers the sinister truth behind the infection and the dark experiments carried out by those in power, forcing him to confront both external horrors and his own haunted past. Players traverse claustrophobic corridors, collect resources, and uncover data logs that expand the story while relying on precise combat and limited supplies to withstand relentless assaults. Despite its haunting visuals, immersive sound design, and intense atmosphere, the game’s release met with a polarized reception, earning praise for its technical achievements but criticism for pacing and combat repetition, ultimately falling short of the lofty commercial goals set by its publisher Krafton.

Set in the distant year 2320, the story begins with Jacob Lee and his partner Max Barrow, seasoned freight haulers under the United Jupiter Company, preparing to retire after completing a final routine mission between Europa and the high-security Black Iron Prison on Callisto. Their journey takes a disastrous turn when their vessel, the Charon, is unexpectedly boarded by the Outer Way, a militant resistance group accused of orchestrating a devastating biological attack on Europa. The violent confrontation sends the ship spiraling back toward Callisto’s surface, resulting in a catastrophic crash that kills Max and leaves only Jacob and the Outer Way’s leader, Dani Nakamura, alive amid the wreckage. Both are swiftly apprehended by Black Iron’s ruthless head of security, Captain Leon Ferris, acting under orders from the calculating Warden Duncan Cole, who inexplicably has Jacob imprisoned without trial. When Jacob regains consciousness, the prison has descended into chaos, its corridors swarming with monstrous, mutated inmates known as biophages, their grotesque forms hinting at a horrifying contagion. Struggling to comprehend his circumstances, Jacob allies himself with a fellow inmate named Elias Porter, who promises a way out in exchange for help. Their uneasy partnership becomes a fight for survival as they navigate the crumbling facility, face unspeakable horrors, and uncover fragments of a dark conspiracy tied to the United Jupiter Company’s experiments, while Jacob’s encounter with Ferris ends violently as the once-powerful officer falls prey to the very abominations he helped contain.
Elias urges Jacob to search for a skilled hacker imprisoned within the Special Housing Unit, claiming that this person possesses the knowledge to override security systems and summon a vessel for their escape from the crumbling prison. Pushing through collapsing corridors and relentless waves of infected prisoners, Jacob eventually discovers that the hacker is none other than Dani Nakamura, the same rebel leader he encountered after the crash. Distrustful and unwilling to cooperate at first, she remains distant as the situation deteriorates around them. Together with Elias, Jacob makes his way toward the hangar, only to face a horrifying ambush from Ferris, who has become partially transformed by the spreading infection. In the violent confrontation that follows, they are thrown onto the icy wasteland of Callisto, where Elias suffers fatal injuries and entrusts Jacob with his recorded memories containing vital truths about Black Iron’s secrets. Dani arrives in a heavy vehicle, retrieves the data, and upon uncovering the depth of the United Jupiter Company’s corruption, reluctantly joins Jacob in his mission. As they uncover the truth behind the company’s illegal experiments, they realize that the Charon had been secretly transporting biological specimens intended for weaponized research, leading to the outbreak that decimated the prison. Their fragile hope of escape collapses when Warden Cole intervenes and destroys their ship, turning the hangar into a fiery wreck. With no other options, Jacob and Dani set out to confront Cole, venturing deep into the ruins of Arcas, the original colony buried beneath the prison complex. Within its remains, they uncover a laboratory containing the preserved body of an alien creature, whose parasitic larvae triggered the mutation now consuming Callisto. The company’s reckless experimentation for profit unleashed chaos that once wiped out the colony. Their search becomes even more perilous when the mutating Ferris reappears stronger than ever, and after another fierce battle, Dani becomes infected. In a final desperate effort to find a cure, they return to Black Iron, but before any plan can form, Jacob is subdued by a security drone and imprisoned again, left isolated amid the growing nightmare as the infection tightens its grip on the doomed moon.
After the terrifying events that left him broken and scarred, Jacob regains consciousness deep within the eerie corridors of Black Iron Prison, his mind clouded by confusion and fragmented memories that refuse to reveal the truth of what happened with Ferris. The silence of the desolate facility is shattered when Dr. Mahler reaches out through his communicator, her voice trembling as she explains that a transport vessel remains their only hope for survival, yet before they can attempt an escape, he must recover her data drives which hold the critical evidence capable of exposing the dark conspiracy behind Cole and Kallipolis’ inhumane experiments. As Jacob moves through the decaying prison, he quickly realizes that something is terribly wrong, the architecture seems altered, hallways stretch into unfamiliar passages, and disturbing visions flicker before his eyes as he struggles to distinguish reality from illusion. His every step becomes a battle against the madness consuming both his mind and the infected ruins surrounding him. When he finally nears the hangar, he discovers the horrifying result of Mahler’s secret research, a grotesque fusion of biophage tissue and robotic machinery that now stalks the facility with deadly precision. In a desperate confrontation, one of these abominations kills Mahler, and her corrupted body reanimates into a monstrous creature that forces Jacob into a tragic and emotional fight for survival. With no other choice, he defeats her and pushes onward, finding a transport waiting amid the chaos, only to be shocked when he recognizes it as the Charon, his old freighter, impossibly repaired and gleaming in the dim light. Clinging to the belief that freedom is within reach, Jacob boards the ship and launches into space, unaware that his apparent escape is only a dream born of his dying mind. In truth, he lies fatally wounded after ensuring Dani’s safety, kept alive briefly by Mahler, who uses his neural link to transmit her final research and evidence through his connection to her. As the transmission concludes and Black Iron crumbles into oblivion, Jacob takes his last breath while Mahler accepts her end, their sacrifices ensuring that the truth will live on even as the prison and its horrors fade into darkness.
