Abiotic Factor is a 2025 survival game developed by New Zealand-based independent studio Deep Field Games and published by Playstack. Set in 1993, players assume the role of scientists stranded in a vast underground research facility in the Australian outback. Players must salvage furniture, collect office supplies, craft tools, build fortifications, defend against paranormal containment breaches, and travel through interdimensional portal worlds in an effort to escape to the surface.
Development began in early 2022 and was conducted remotely by a team of around ten developers. Its co-op gameplay was influenced by titles such as Valheim and Sea of Thieves, while its art direction and setting draw inspiration from Valve'sHalf-Life series. Abiotic Factor was released for Windows, PlayStation 5, and Xbox Series X/S on 22 July 2025, following an early access release in May 2024. During its stage in early access, the game has received three major updates: "Crush Depth" on 12 August 2024, "Dark Energy" on 4 February 2025, and, along with its full release on 22 July 2025, "Cold Fusion".
Abiotic Factor received critical praise for its genre-blending design, narrative, and multiplayer integration. The game received an overwhelmingly positive reception on Steam and was nominated for "Best Multiplayer Game" at the 2024 Golden Joystick Awards.
Gameplay
Abiotic Factor is a survival game played in a first-person perspective. As scientists trapped in an underground research facility called GATE in the year 1993, players must craft tools and weapons, fight various alien creatures, and build their own home bases, alone or online with up to five other players.[5] The game's low-resolution stylized three-dimensional graphics and sense of humour are inspired by Half-Life.[6][7]
Players create their own character and assign them one of various science-inspired specialisations which determine their uniform, attributes, and may add permanent buffs or debuffs. The game features a role-playing games–style experience system and a skill tree, allowing players to upgrade their characters after the initial character creation.[8][9]
While exploring and progressing through the GATE complex, players need to manage their personal needs—such as hunger, thirst, continence, and fatigue—as well as their protection from environmental factors like temperature and radiation. A day-night cycle determines the players' access to power; at night, all lights in the research facility are turned off and interdimensional portals may appear around player bases, allowing enemies to attack them.[10] To defend against these raids and various alien creatures inspired by the SCP Foundation[9], as well as robotic and human threats roaming the facility, players need to disassemble furniture and collect items in order to craft improvised weapons and gear.[11][12]
Abiotic Factor's linear story leads players through several sectors of the underground complex which can be unlocked by crafting specialised tech, and through multiple alternate dimensions (called "Anteverses") accessible via portals. These portal worlds range in style and function and offer unique resources. Unlike the main building, they also reset twice a week. Players are thus encouraged to repeatedly visit and gather crafting materials from these worlds.[13][5] The game's plot is conveyed through audio logs and emails found on numerous terminals throughout the facility; voiced non-player characters (NPCs) provide additional exposition and guidance for progressing the story.[14] It takes about 50 to 60 hours to complete the game.[15]
Synopsis
Setting
Abiotic Factor takes place in 1993 within a vast underground research facility run by Garrick Advanced Technology Enterprises (GATE). Built to contain and study anomalous objects and entities, the facility houses a wide array of researchers across laboratories, power reactors, residences, and manufacturing sectors. Following the invention and successful testing of the "Dark Lens" in 1988—which enabled both temporal and spatial travel—the facility shifted its focus to studying “perforations” and the flora and fauna of the so-called "Anteverses." These rifts allow instantaneous travel across Earth, to distant exoplanets, into the past or the future, and even to parallel universes.
Several factions operate within or against GATE during the events of Abiotic Factor. The Gatekeepers, GATE’s internal security force, were originally tasked with protecting researchers and containing anomalous entities. While most remain loyal to GATE, a splinter faction known as "The Unlost" broke away, convinced that resisting the flow of fate is meaningless and that humanity’s role is predetermined. "The Order" is a rival organization with origins in an ancient scholarly sect dedicated to the study and suppression of anomalous phenomena. By the late 20th century, it had transformed into a secretive paramilitary group, clashing with GATE and attempting to seize control of perforation technology for its own purposes. A recurring threat from the Anteverses is the Exor, an alien species designed to colonize universes on behalf of a higher intelligence known as the "Wayseeker".
Plot
Abiotic Factor opens in the Western Australian outback, where the player begins their first day as a scientist at GATE. Beneath a remote mining shack lies a sprawling underground facility built into a former lithium mine. After a brief orientation, an emergency diverts the player into the Office Sector, where a sudden rift kills researcher Dr. Jaeger and hostile creatures overrun the halls. Survivors explain that GATE has long studied “perforations,” portals to parallel worlds known as Anteverses, and that an opposing paramilitary faction called the Order has infiltrated the complex. Attempting escape, the player is drawn into Flathill, a fog-shrouded research site in South Dakota accessible through the Silos. There they learn of the Order’s assault and regroup with survivors Abe and Janet. Their plan to flee through Manufacturing fails when the surface tunnel collapses, forcing cooperation with Dr. Frake, who uses a Synchrotron to breach deeper into the Laboratories. Along the way, the player discovers GATE’s past: the Dark Lens, built in 1988, opened the first perforation and initiated decades of research into alien ecosystems and entities. In the Laboratories the player encounters Dr. Cahn, once presumed dead but later revealed to be an anomalous shapeshifter (IS-0012). He aids in reaching the main elevator, though it malfunctions, leaving the only escape route through the Hydroplant.
The Hydroplant powers the entire complex but has been seized by the Order. Abe and Janet are stranded there after their planned submarine escape fails. The player meets Dr. Elanor Newman, creator of the Dark Lens, who explains that the only remaining portal equipment lies within the nearby Reactors, accessible through a blocked spillway. To clear the path, the player assists Kylie Muir, a cancer patient whose mind was transferred into a GATE neural device, recovering materials from both the Hydroplant and a connected Swiss facility called Voussoir. With her help, the spillway is restored and the descent to the Reactors begins.
The power services above the Reactors are overrun by alien flora. Guided by K18, a reprogrammed security robot, the player enters a perforation to recover antifungal chemicals. Inside, they encounter remnants of an intelligent Exor society and briefly glimpse the “Wayseeker,” a higher entity linked to their spread. Returning, they clear the infestation and enter the Reactors, where Dr. Cahn explains that four reactors must be reactivated to restore portal systems shut down by the Gatekeepers. As the player fights Order troops, Exor, and hostile Gatekeepers, a splinter faction called the “Unlost” offers cryptic reflections, suggesting the journey is guided by fate. With the reactors restored, a portal opens to a GATE site in Finland, once home to the Wayseeker’s study. Urged by Cahn, the player banishes the entity and briefly passes through the Order’s headquarters, uncovering its origins as an ancient academic sect that has long suppressed anomalous knowledge. There they discover the “Sun Disk,” an alien reply to the Voyager Golden Records, which had been intercepted by the Order.
Empowered by the Sun Disk, the player enters the frozen Residence Sector, flash-frozen after the Gatekeepers opened a portal to flee with the Dark Lens. Amid glacial ruins and frozen survivors, the player discovers the Lens suspended in a vast void where the Gatekeepers prepare their escape. There they learn their own assignment to GATE was diverted by the entity posing as Dr. Cahn. Passing through portals, the player glimpses alternate futures of GATE, including an apocalyptic wasteland and a technologically advanced timeline. The path leads to a polar island near South Georgia, where the player confronts the Wayseeker. After its defeat, the entity summons a massive perforation, releasing the energy of thousands of Anteverses onto Earth. After the finale, Dr. Cahn reveals himself as a servant of the Wayseeker, admitting he engineered the entire sequence of events to bring about the world’s end.

Abiotic Factor was developed entirely remotely[16] by a team of around ten.[1][17] Managing time zone differences posed a challenge for the New Zealand-based studio, but this approach also enabled collaboration with creative talent from around the world.
At the 2024 New Zealand Game Developers Conference (NZGDC), Narrative Designer Henry Feltham recounted the origin story of Abiotic Factor. In 2020, when Feltham worked on a game for RocketWerkz, he met Geoff "Zag" Keene—who worked on the social deduction gameUnfortunate Spacemen at the time—and Kate Colvin. Feltham later joined Keene and Colvin at Deep Field Games in early 2022.[16][2]
Deep Field Games decided to develop a "vibey" game with a heavy focus on co-op play, stating that multiplayer titles like Valheim, Seaof Thieves, and Hell Let Loose had kept them "sane" throughout the COVID-19 pandemic. Abiotic Factor was one of a handful of game ideas prototyped for this purpose. The team sought to infuse the survival game genre with elements from both cozy and horror games that they personally enjoyed playing and combine these with a retro aesthetic.[16]
Before development began, Abiotic Factor received funding from Alt Ventures' "Kiwi gaming fund".[16][18] In June 2022, the New Zealand government-backed Centre of Digital Excellence (Code) provided Deep Field Games with a NZ$150,000 grant[1][19] and covered the team's expenses to attend PAX Australia in October 2022 where an early demo was on show and playable.[20][21] Aware of the game's resemblance to the Half-Life series, the team pitched their game to attendees as follows:
It's scientists in an underground lab. You make crazy shit to escape to the surface. But you're scientists. You're not Gordon Freeman, Doom Guy, Master Chief. [...] You're smart; but you're not strong.
—Henry Feltham, at NZGDC 2024
By the end of 2022, thanks to their appearance at PAX Australia, Deep Field Games had received some publishing offers. They ultimately decided to team up with Playstack, who also ended up publishing Balatro.[20][16]
On 23 August 2023, Abiotic Factor was a featured game at the "Future Games Show" at Gamescom 2023.[22]
One of the challenges for the team was reversing the "power fantasy" trope common in many video games by slowing down progress and providing solutions to early game challenges that prioritise brain over brawn. The concept of "Anteverses", alternate dimensions that serve as dungeons, was incorporated early in development, giving the team freedom in the range of worlds they could create.[16]
Abiotic Factor's director Geoff "Zag" Keene cites Half-Life and its second expansion Half-Life: Blue Shift as core inspirations for their game. The game features many elements adapted from the Half-Life series, such as trams, vending machines and lab coats. The game's setting, the GATE research facility, is built to structurally resemble Half-Life'sBlack Mesa Research Facility. The crafting system, which required players to drag materials into slots to find a valid combination and unlock an item, is loosely based on the puzzle game Wordle.[2]
Keene criticised the survival genre's "grindy" nature in an interview with PC Gamer. As a result, one goal during the development of Abiotic Factor was to create a slower, less punitive style of gameplay that focused on exploration, adventure, and role-playing. Keene said the team was inspired by The Indie Stone's Project Zomboid and its "Moodle" system, which reduces reliance on meters, instead using voice lines and HUD pop-ups. In the same interview, he also noted that immersive sims had an unintended influence on the game.[12] In an interview with Edge, Keene elaborated on the fragile nature of survival games and how the team distinguished Abiotic Factor from the genre. He stated, "[Survival games] release and get 100 reviews on Steam, if they’re lucky, and then they just fall off the map. [...] You’ve got to do something different with it."[2]
Release
The game entered a brief playtest period from 12 December 2023 to 1 January 2024 before being released into early access on Steam on 2 May 2024.[8][23]
After more than a year of updates introducing new mechanics and ecosystems, the "Cold Fusion" update was announced in June 2025 for release the following month, marking the game’s transition out of early access.[25][26] Alongside this, PlayStation 5 and Xbox Series X/S versions were confirmed.[27] The console versions of the game were ported by a partner.[15]
The full release in July 2025 also saw the game added to PlayStation Plus and Xbox Game Pass at launch.[28][29] By August 2025, Abiotic Factor had sold 1.5 million copies.[30]
Abiotic Factor received critical acclaim upon its full release. On Metacritic, as of August 2025, the game holds a score of 88/100 based on 4 critic reviews.[31]
Morgan Park of PC Gamer described it as "one of the greatest survival crafting games ever made" and a "classic in the making," awarding it a score of 92%. He praised the game for its unique portal worlds, breadth of content and intriguing combat options but noted that combat can feel clunky at times.[5][32]XboxEra described Abiotic Factor as a "charming take on the survival genre, full of great mechanics and systems, an engaging story and world" and praised it as "an absolute blast to play with friends." They scored it 8.2 out of 10.[10]Game8 awarded Abiotic Factor a score of 86/100, commending its blend of "humour, tension, and sci-fi chaos," as well as its replayability. However, Game8 also notes a couple of rough edges—some mechanics remain unexplained, and solo play can feel overwhelming—although these issues don't detract from the overall satisfying experience.[14]
Abiotic Factor had an "Overwhelmingly Positive" rating on Steam in early access and at launch, with a 95.5% player satisfaction rating from over 24,000 reviewers at the time of the game's full release.[1][33]
Deep Field Games, based in Dunedin, Otago, achieved international success with Abiotic Factor.[20] A majority of the game’s players are located in the United States (38%) and China (21%).[34]
Accolades
Abiotic Factor was nominated for "Best Multiplayer Game" at the 2024 Golden Joystick Awards.[35] At the New Zealand Games Festival's "Pavs Awards", it won the "Grand Prize" and the award for "Excellence in Design", and was also nominated for the awards "Excellence in Narrative" and "Excellence in Accessibility".[36]
