At the Gamescom 2026 trade fair in Cologne, Owlcat Games provided a comprehensive third look at their highly anticipated project, The Expanse: Osiris Reborn. Following a developer walkthrough of the Pinkwater Station level in 2025 and a subsequent Closed Beta test, this latest demonstration offered a deep dive into a significant mission arc. The demo, accompanied by insights from Creative Director Alexander Mishulin, showcased the title’s transition from conceptual gameplay to a polished third-person action RPG that remains deeply rooted in the studio’s narrative-heavy heritage.
The Expanse: Osiris Reborn represents a significant departure for Owlcat Games, a studio previously renowned for isometric, turn-based, and real-time-with-pause titles such as Pathfinder: Wrath of the Righteous and Warhammer 40,000: Rogue Trader. By adopting a third-person perspective and real-time combat mechanics, the studio aims to capture the visceral tension of James S.A. Corey’s universe while maintaining the complex decision-making and character development that fans have come to expect from their catalog.
Dual Protagonists and the Sibling Dynamic
The demonstration began by clarifying a unique aspect of the game’s character creation suite. Players are tasked with building two characters simultaneously: the protagonist and their twin sibling. Because the characters are twins, certain aesthetic and genetic choices carry across both models, creating a visual cohesion that grounds the narrative in a familial bond.
The sibling, identified simply as J, serves as a constant companion throughout the journey. Mishulin described J as the more "hot-headed" of the pair, serving as a narrative foil to the player’s actions. A central pillar of the game’s RPG systems is the evolving relationship between the twins. During a dialogue sequence in the demo, the player was presented with a choice to support J or offer a curt "J, shut up" response. Mishulin noted that consistent dismissiveness leads to a perceptible shift in J’s personality; the sibling becomes increasingly reserved, less emotional, and less prone to venting frustrations. These interpersonal shifts are not merely cosmetic, as Owlcat hinted at significant late-game consequences tied to the strength and nature of this bond.
Infiltration and the Protogen Conspiracy
The mission featured in the Gamescom demo involved a high-stakes infiltration of a facility operated by Protogen, the antagonistic corporate entity central to the early lore of The Expanse. The twins are smuggled into the Prospero facility inside shipping containers—a sequence Mishulin explicitly compared to the Thoth Station raid depicted in the second season of the television adaptation.
The narrative context is dense: Prospero is the Protogen branch responsible for Project Caliban, the clandestine program focused on the creation of human-Protomolecule hybrids. The player characters are disguised as operatives from Osiris, a third, even more secretive branch of the corporation. This disguise facilitates a "social stealth" environment where Protogen personnel treat the players with a mixture of professional deference and underlying resentment.
Owlcat’s signature writing style was evident in the environmental storytelling. While navigating the facility, the protagonists overheard Protogen guards discussing mundane administrative transfers. J pointed out the cognitive dissonance of these "grunts"—individuals who participated in the mass slaughter of asteroid populations yet view themselves as mere cogs in a bureaucratic machine. While players can interact with these NPCs to offer career advice, they cannot directly challenge their morality without blowing their cover, reinforcing the tension of the undercover operation.
Translating CRPG Mechanics to Action-Adventure
One of the most significant challenges for Owlcat has been translating traditional RPG "skill checks" into a third-person action context. In Osiris Reborn, environmental checks are triggered contextually and often manifest as immersive minigames rather than simple dice rolls. For example, a perception check involves a targeting circle that shrinks to pinpoint a hidden object. Unlike traditional CRPGs where a failed roll might lock content permanently, players can re-trigger these checks by re-entering the detection range, though the difficulty may vary.
The game also features a sophisticated "party-wide" stat system. Skill checks draw from the highest relevant value across the entire crew, including companions who are not physically present on the field but are assisting via comms from the ship. When companions are physically present, they assist with environmental interactions—such as moving heavy debris—and provide unprompted callouts for points of interest. This system ensures that the player’s investment in their crew’s development remains relevant regardless of the specific mission composition.
Narrative Choice and the "Invoice Problem"
Mishulin outlined a three-tier system for player choice that governs the narrative flow of Osiris Reborn:
- Immediate Decisions: Choices that result in immediate, localized changes to the current environment or NPC reactions.
- Short-Term Consequences: Decisions that impact the outcome of the current mission or the immediate survival of NPCs.
- Long-Term Impact: Macro-level choices that ripple through the entire campaign, influencing the game’s multiple endings and major political shifts in the Solar System.
The demo emphasized exploration by deliberately withholding objective markers. This design philosophy is intended to mirror the characters’ own lack of information. To progress through a security checkpoint, players had to solve a multi-step "information-gathering puzzle." This involved locating a physical inventory number on a shipping crate, downloading real invoices from a restricted terminal, and having the crew’s medic, Alicia, forge a digital authentication signature. This approach replaces the standard "interact with the door to open it" mechanic found in many shooters with a process that feels grounded in the world’s technical reality.
Combat Evolution and the Solar Forge
The atmosphere of the demo shifted dramatically when the infiltration was compromised. An external attack by a third party, combined with the escape of a Caliban hybrid, turned the mission into a survival horror experience. The redesigned Caliban hybrid features crystalline spikes that serve as both a visual update and a gameplay mechanic. These creatures are largely immune to standard ballistic weaponry, forcing players to rely on environmental hazards and tactical retreats.
Combat involves a fluid exchange between various weapon types, such as SMGs for close encounters and sniper rifles for long-range precision. Tactical depth is added through environmental interactions; for instance, detonating the fuel tanks of enemy flamethrower troopers can cause massive area damage.
The climax of the demo took place in Ganymede’s hydroponic farms. To defeat the seemingly invincible hybrid, the team utilized a "Solar Forge"—a technique involving the farm’s solar panel arrays to focus light into a beam capable of reaching 3,000 degrees Celsius. Mishulin emphasized that this mechanic is based on real-world physics, vetted by the studio’s science consultants to ensure the game adheres to the "hard science fiction" standards of the franchise.
Technical Development and Release Timeline
Following the demo, Alexander Mishulin addressed feedback from the recent Closed Beta. One significant change resulting from player input was the recasting of the male protagonist’s voice actor to better fit the narrative tone. Additionally, the studio has focused heavily on combat animations to ensure responsiveness, a critical factor for a studio moving from isometric to third-person gameplay.
Technical optimization remains a priority as the game approaches its final stages. Owlcat confirmed that the title will launch simultaneously on PC and consoles, including the Xbox Series S. While the Series S version will require adjusted graphical settings, Mishulin expressed confidence that the visual integrity of the game would remain intact.
Timeline of The Expanse: Osiris Reborn Development:
- Late 2024: Project Announcement.
- Gamescom 2025: First public demo (Pinkwater Station).
- Early 2026: Closed Beta test and initial player feedback.
- Gamescom 2026: Feature-complete mission demonstration.
- Spring 2027: Targeted release window.
Broader Impact and Market Implications
The Spring 2027 release window sets up a significant period for science fiction RPG fans. Osiris Reborn is slated to launch within weeks of Exodus, the new IP from Archetype Entertainment (led by BioWare veterans), which is currently scheduled for April 7, 2027.
While Exodus appears to lean into space opera and time-dilation mechanics, Osiris Reborn occupies the "hard sci-fi" niche, focusing on the sociopolitical tensions between Earth, Mars, and the Belt. For Owlcat Games, the success of this title will determine the studio’s viability as a multi-genre developer. By combining the rigorous narrative standards of the CRPG world with the accessibility of a third-person shooter, Owlcat is attempting to bridge a gap that has remained largely vacant since the conclusion of the original Mass Effect trilogy.
As the industry moves toward 2027, the focus for Owlcat remains on "polishing and balancing." With the core content largely complete, the remaining months of development will be dedicated to refining the boss encounters—such as the Solar Forge fight—and ensuring the branching narrative paths provide the depth that the studio’s fanbase demands. The Expanse: Osiris Reborn appears poised to be a definitive adaptation of the source material, prioritizing immersion and scientific plausibility over traditional power fantasies.
