Frictional Games, the studio behind the horror classics Amnesia: The Dark Descent and the philosophical sci-fi masterpiece SOMA, has released a ten-minute gameplay walkthrough for their next title, ONTOS. Co-published with Kepler Interactive, this footage offers the clearest look yet at what the studio describes as a spiritual successor to SOMA—a statement that carries immense weight for fans of narrative-driven, atmospheric science fiction. The gameplay reveal transforms abstract promises into tangible mechanics, showing a universe that blends psychological dread with methodical engineering puzzles.
The ten-minute vignette places players firmly inside the boots of Aditi Amani, a skilled engineer whose search for her estranged father pulls her into the depths of Samsara, a repurposed moon hotel built atop the wreckage of a failed mining colony. The setting immediately evokes the claustrophobic, industrial corridors of SOMA, but the gameplay shown suggests a pivot toward more direct player agency. Throughout the sequence, Amani navigates an interconnected labyrinth where each environment—from crumbling hotel suites to cavernous mining shafts—tells its own fragment of a larger, unsettling story.
ONTOS is being developed using Frictional’s new proprietary HPL4 engine, marking a significant technical leap for the Swedish team. The engine, which succeeds the HPL3 that powered SOMA and Amnesia: Rebirth, is designed to deliver more organic environmental interactions, complex lighting, and physics-driven puzzles. The gameplay footage demonstrates these capabilities: objects react to pressure and weight, doors creak with distinct material properties, and the environment feels less like a static backdrop and more like an active participant in the mystery.
What Is the Gameplay in ONTOS Like, and How Does It Differ from SOMA?
For readers unfamiliar with Frictional’s earlier work, the immediate question is how ONTOS diverges from the studio’s celebrated 2015 title. The ten-minute showcase reveals a move away from the pure survival horror of Amnesia and the existential horror of SOMA toward a more deliberate, puzzle-solving, exploration-driven experience. ONTOS emphasizes player ingenuity with multiple ways to overcome obstacles. In one sequence, Amani must bypass a sealed door: she can either rewire a control panel, find an alternate ventilation route, or use a nearby environmental object to create a distraction. This flexibility recalls the immersive sim genre—games like Prey or Deus Ex—but filtered through Frictional’s signature atmospheric tension.
The narrative structure also appears more personal. Whereas SOMA dealt with the cosmic horror of consciousness transfer and the nature of identity, ONTOS roots its mystery in a daughter’s search for her father. The emotional stakes are grounded, yet the setting—a moon hotel built over a failed colony—introduces grander questions about exploitation, memory, and what happens when corporate ambition outpaces ethics. The gameplay footage shows Amani discovering audio logs, holographic messages, and environmental clues that gradually piece together her father’s last known activities.
Another key difference is the pace. SOMA was often a gauntlet of hiding from hostile entities; ONTOS appears to offer more breathing room. The ten-minute reel shows no immediate threats—only the quiet tension of a derelict structure. This does not mean the game lacks danger, but it suggests Frictional is prioritizing exploration and story over constant survival pressure. Players can expect moments of genuine vulnerability, but the focus is on understanding rather than fleeing.
Who Is in the Cast of ONTOS?
The game features a notably high-profile cast anchored by Stellan Skarsgård, the veteran Swedish actor known for his roles in Chernobyl, Dune, and the Pirates of the Caribbean series. While the specific character he portrays remains undisclosed, his involvement underscores Frictional’s ambition to elevate the narrative weight of the project. Skarsgård’s deep, resonant voice and ability to convey moral complexity make him a natural fit for a story about legacy, guilt, and discovery. Frictional has previously worked with strong voice talent, but securing an actor of Skarsgård’s caliber signals that ONTOS is intended to rival the narrative ambition of the best cinematic science fiction.
How Was ONTOS First Revealed, and What Was the ARG?
The game’s existence was not announced through a standard trailer drop. Instead, Frictional orchestrated an alternate-reality game (ARG) that began in September 2025. The ARG was triggered by a discovery hidden within a free tenth-anniversary update for SOMA on PC. Players who updated the game found a cryptic message, which led to a trail of websites, social media accounts, and encrypted communications. This approach is rare for a studio of Frictional’s size and reflects their understanding of their dedicated fanbase. It also generated organic curiosity and speculation, ensuring that when the game was officially revealed, a core audience was already invested in its lore. The ARG’s conclusion pointed directly to ONTOS, establishing the title as a mystery before any gameplay was shown.
When Will ONTOS Be Released, and on Which Platforms?
ONTOS is scheduled for release in 2027. It will be available on PlayStation 5, Xbox Series X|S, and PC via both Steam and the Epic Games Store. The 2027 date may seem distant, but it reflects the complexity of building a fully realized world using a new engine and a custom narrative system. Frictional is known for meticulous craftsmanship rather than rushed production cycles. The cross-platform release also signals confidence in the game’s broad appeal beyond the PC-centric horror community.
What Is the HPL4 Engine, and Why Does It Matter?
The HPL4 engine is Frictional’s fourth-generation proprietary technology platform, built entirely in-house. Unlike many studios that license Unreal Engine or Unity, Frictional has consistently developed its own tools to achieve a specific, handcrafted look and feel. HPL4 promises vastly improved physics simulation—objects in ONTOS exhibit realistic weight, friction, and destructibility. The engine also handles dynamic lighting with greater fidelity, allowing for scenes where the contrast between harsh artificial light and total darkness becomes a gameplay element. Given that Frictional’s games rely heavily on environment storytelling, a more capable engine allows for richer detail in every room. The ten-minute gameplay footage shows realistic reflections on water surfaces, dust motes floating in shafts of light, and subtle animation in objects that react to the player’s presence. For a game set in a repurposed moon hotel, these details create a convincing sense of place.
What Are the Key Themes of ONTOS Based on the Gameplay?
While direct plot details remain sparse, the gameplay footage and setting suggest several thematic undercurrents. The name ONTOS is a Greek word meaning “being” or “existence,” hinting at philosophical questions about identity and reality—a hallmark of Frictional’s writing. The Samsara moon hotel, built atop a failed mining colony, evokes ideas of corporate exploitation and the reuse of tragedy. The hotel itself was a second attempt at profit after the mining operation collapsed, implying that the lives of the original colony workers were disposable. Aditi Amani’s search for her father intersects with this corporate history, suggesting that personal and systemic guilt are intertwined. The gameplay emphasizes engineering puzzles, placing the player in the role of someone who must understand and manipulate machinery to progress. This mechanical literacy mirrors the ethical dilemmas of playing god with technology—a theme Frictional explored deeply in SOMA.
How Does ONTOS Fit into Frictional Games’ Legacy?
Frictional Games began as a small independent studio known for the Amnesia series, which revitalized the survival horror genre in the early 2010s. With SOMA, they proved that horror could be intellectually profound, using science fiction to ask questions about consciousness that linger long after the credits roll. ONTOS appears to be a natural evolution: still atmospheric, still narrative-driven, but with more emphasis on player choice and flexible puzzle-solving. It also represents a step toward a more mainstream audience without sacrificing the studio’s core identity. The involvement of Kepler Interactive, a publisher with strong distribution for indie titles, supports this reach. Fans of SOMA will find familiar territory in the abandoned corridors and recorded messages, but the focus on multiple problem-solving paths suggests Frictional is listening to criticisms about linearity in their earlier works.
What Are the Technical Requirements and Performance Expectations?
As of the gameplay reveal, no official system requirements have been announced. However, given the HPL4 engine’s demonstrated capabilities, players should expect moderate to high hardware demands. The game will target 60 frames per second on current-generation consoles, with the PC version likely supporting high-refresh-rate displays and ultrawide aspect ratios. Ray tracing may be included given the engine’s lighting fidelity, though Frictional has not confirmed this. The game’s reliance on physics-based puzzles means CPU performance will be as important as GPU power. It is reasonable to assume that a solid mid-range PC from 2025 or later will handle the game at 1080p with high settings, while 4K gameplay will require top-tier hardware.
How Long Will ONTOS Be, and What Is the Replayability?
Frictional games typically offer 10 to 15 hours of main story content, with additional exploration for those who seek every lore fragment. ONTOS, with its emphasis on multiple solutions to obstacles, could potentially extend that playtime for players who experiment with different approaches. The interconnected nature of Samsara suggests that players can revisit areas with new tools or knowledge, opening narrative branches. While the game is primarily a linear story, the variety of puzzle solutions encourages a second playthrough to see alternate outcomes or discover missed details. This design philosophy positions ONTOS closer to immersive sims in terms of player freedom, even if it retains a tightly written narrative spine.
What Can We Learn from the Ten-Minute Gameplay Footage About the Game’s Development?
The footage, which was likely captured from an early build, reveals a polished but not yet final product. The animation of Aditi Amani is smooth, with realistic weight when she climbs or interacts with objects. The sound design, a crucial element in Frictional games, is present in the background—echoes, distant machinery hums, and the creak of metal. The user interface is minimal, suggesting the game wants players to be immersed without HUD clutter. Importantly, the gameplay shows no loading screens between areas, indicating that the world is built as one continuous space. This technical achievement is demanding but essential for maintaining tension. The absence of combat in the shown sequence also raises questions: will ONTOS have any hostile forces, or is the threat purely environmental and psychological? The footage leans toward the latter, but it is too early to rule out traditional Frictional-style encounters.
Why Is the Spiritual Successor Label Important for ONTOS?
Frictional explicitly calls ONTOS a spiritual successor to SOMA, a game that has attained cult status for its narrative ambition and tragic ending. This term implies that ONTOS is not a direct sequel—there will be no returning characters or continuation of SOMA’s underwater setting. Instead, it promises a similar tone, thematic depth, and philosophical inquiry. The label sets expectations: players anticipating a carbon copy of SOMA may be disappointed by the shift toward more open puzzle design, while those hoping for a fresh take on the same intellectual horror will likely be satisfied. It also signals to the market that Frictional considers ONTOS their most important project since SOMA, and likely a flagship title for the HPL4 engine.
What Are the Similarities and Differences Between ONTOS and Other Sci-Fi Horror Games?
Comparisons to Dead Space and Alien: Isolation are inevitable given the setting on a derelict space station. However, ONTOS distinguishes itself by focusing on intellectual puzzles and narrative rather than combat. The moon hotel aesthetic also recalls The Station and Observation, but Frictional’s signature storytelling—where every object has a story and every room is a fragment of tragedy—is unique. The game’s most direct competitor may be Returnal, another title set on an alien world with strong narrative and exploration components, but ONTOS is linear and story-focused rather than a roguelike. Its closest spiritual kin remains SOMA, which itself drew comparisons to Bioshock and System Shock 2. ONTOS appears to modernize that tradition by adding flexible gameplay systems and a more personal story.
How Can Players Prepare for ONTOS Before Its 2027 Release?
For those eager to experience Frictional’s approach before ONTOS arrives, the obvious recommendation is to play SOMA, which remains available on all modern platforms. The tenth-anniversary update, which contained the original ARG clues, is still included and offers additional lore and a new game mode. Players should also try Amnesia: The Dark Descent and Amnesia: Rebirth to understand the studio’s evolution in horror design. Frictional’s earlier work, like the Penumbra series, is older but shows the foundation of physics-based puzzle solving that ONTOS will refine. Following the studio’s social media and official website will be the best way to stay informed about future reveals, such as a more detailed story trailer or a playable demo. The 2027 release date means there will likely be multiple showcases and gameplay deep dives over the next two years.
The ten-minute gameplay reveal of ONTOS signals a deliberate maturation of Frictional Games’ craft. By blending the emotional gravity of a personal mystery with the vast, lonely scale of a moon hotel and the philosophical weight of their previous work, they are constructing a title that could resonate as deeply as SOMA did a decade ago. The wait until 2027 may test patience, but the care evident in this footage suggests that Frictional intends to deliver a fully realized, mechanically rich, and unforgettable journey into the unknown.
