That Which Remains is scheduled to launch in Early Access on Steam on October 27, 2026. Developed by Remaining Games and published by Interdimensional Games Inc, the title is a 1–4 player sci-fi ghost-hunting horror extraction simulator. A free playable demo is currently available on the official Steam store page, and the developers have confirmed that all progress earned in the demo will transfer directly into the full release.
Early Access Release Date and Demo Availability
Remaining Games confirmed that That Which Remains enters Early Access on October 27, 2026. The development team, consisting primarily of three creators, intends to keep the game in Early Access for roughly a full year while finalizing the overarching story and expanding contamination zones.
Key launch and release milestones include:
- Steam Demo Release: A free standalone demo is live on Steam, allowing players to test the core investigation loop. Progress made during the demo carries over to the Early Access launch.
- Early Access Launch Date: October 27, 2026.
- Early Access Scope: The launch build features the complete core loop, 12 to 13 entity types, 18 investigation tools, a day/night weather difficulty modifier, base upgrades, crafting, and four excursion maps alongside a blueprint rural house map.
- Pricing Strategy: The developers stated that the Early Access entry price is the lowest it will ever be, with potential price increases planned as major content milestones roll out.
Setting and Core Gameplay Loop
Set around the year 2250 C.E., humanity has built a supposed utopia that has eradicated war, scarcity, and death. However, this society runs on "Enticine"—liquefied trauma extracted from Neurospatial Parasitic Entities, commonly understood as ghosts. Because a trauma-free utopia can no longer generate its own fuel, the corporation Entitech conscripts "Relics"—people pulled from past eras of human suffering—to travel across time and extract trauma directly from contaminated historical zones.
Players operate under a strict extraction structure:
- Excursion: Enter contaminated historical zones, such as abandoned houses or an arctic prison, to locate entity manifestations.
- Identification: Gather primary and secondary evidence to correctly determine the entity type.
- Extraction: Trap the entity or harvest Enticine directly using capture tools, while securing trauma-laced scrap across the map.
- Quota Fulfillment: Return to base before the extraction portal wanes and deposit the collected Enticine to fulfill an escalating daily quota. Surplus fuel powers base systems.
Investigation Tools and Entity Mechanics
That Which Remains equips players with roughly 18 investigation devices to detect supernatural presence. Entities interact dynamically with the environment by shattering furniture, throwing objects, flickering lights, and manipulating room temperatures.
Investigation Features
- V.O.I.C.E. Technology: Players can speak directly into the Spirit Box using their own microphone. Entities and their past victims feature unique personalities and respond dynamically to specific words and phrases. Players can also communicate with eliminated teammates through the Spirit Box.
- Communication Systems: In-game communication relies on proximity voice chat featuring per-room acoustic modeling, as well as walkie-talkies for long-distance team updates. Entities react to player speech.
- Evidence Gathering: Relics track anomalous EMF signals, extreme temperature shifts, spirit box audio, illusions, and ghost orbs viewed through camera lenses.
- 12 Entity Types: The initial design includes distinct entity profiles, each displaying specific behavioral traits, mood states, and violent reactions toward player actions.
Base Management and Sanity Recovery
Between excursions, players return to a persistent base hub. Sanity functions as a combined metric representing physical exhaustion, fear, and cognitive strain. If a Relic's sanity depletes, survival becomes increasingly difficult.
To sustain operations, players manage the following facilities:
- Sanity Recovery: Relics recover cognitive stability by sleeping in personal cabins, drinking coffee, playing chess or basketball, and utilizing the serenity chamber base upgrade.
- Customization and Upgrades: Cabins and decorative items persist across sessions. Players spend Base Power to unlock new functional facilities and spend Energy Credits to craft higher-tier survival gear.
- Leveling: Completing excursions grants player experience, unlocking specialized personal upgrades and advanced equipment loadouts.
