The That Which Remains game is an upcoming 1–4 player sci-fi ghost-hunting horror extraction simulation developed by Remaining Games and published by Interdimensional Games Inc (iDGi). The game is officially scheduled to launch in Steam Early Access on October 27, 2026, for PC. A free playable demo is available now on Steam, allowing players to test the game ahead of Steam Next Fest, with all demo progress transferring directly to the full release.

In That Which Remains, players take on the role of Relics—humans abducted from eras of suffering and conscripted by a dystopian corporation named Entitech. The game blends supernatural investigation with extraction mechanics, tasking squads or solo players with identifying hostile entities, extracting liquefied trauma, and returning to base to meet strict daily quotas.

Release Date and Early Access Schedule

According to the official announcement by Remaining Games and Interdimensional Games Inc, That Which Remains will release in Early Access on Steam on October 27, 2026. The project was developed by an indie core team of three creators who previously worked on titles such as Consortium.

The developers stated on their official Steam page that the game is planned to spend approximately one full year in Early Access while they complete the overarching narrative campaign. This timeline may be extended if player demand leads to an expansion of features and scope. The studio also confirmed that the initial Early Access price tag will be the lowest price offered, with potential price revisions arriving alongside major content expansions or the eventual 1.0 release.

How to Play the Demo and Progress Carryover

Players looking to test the game before launch can download the free That Which Remains demo directly from Steam. The demo was released on October 7, 2026, in preparation for the October Steam Next Fest.

Key details confirmed by Remaining Games regarding the demo include:

  • Full Save Transfer: All progress, levels, and items acquired while playing the free demo will carry over directly into the Early Access release on October 27, 2026.
  • Early Content Access: Players can experience early excursion maps (including residential locations and commercial sites like arcades and gas stations), test investigation tools, and experience the base hub.

Core Gameplay: Hunting, Extraction, and Daily Quotas

That Which Remains merges the investigative mechanics of games like Phasmophobia with the high-stakes extraction loops of Lethal Company. Set around the year 2250 C.E., humanity has built an apparent utopia that has eradicated war, illness, and poverty. However, this perfection relies entirely on "Enticine"—liquefied human trauma harvested from hostile apparitions known as Neurospatial Parasitic Entities.

Because a peaceful society can no longer produce trauma, Entitech dispatches Relics across space and time into contaminated historical hot zones to harvest it.

Investigation and Capture Tools

Each excursion drops players into a contamination zone to collect evidence, pinpoint the specific entity type, and extract resources. Investigation relies on approximately 18 distinct equipment items, including:

  • EMF Detectors: Gauge electromagnetic spikes when entities interact with the room.
  • Thermal Sensors: Measure severe temperature shifts, such as sudden drops below freezing or intense heat anomalies.
  • Spirit Boxes: Facilitate direct speech with spirits.
  • Video Cameras & Night Vision: Allow players to spot ghost orbs and floating manifestations in pitch-black interiors.
  • Traps & Capture Devices: Used once the entity is identified to secure Enticine before extracting back to base.

V.O.I.C.E. Technology and Audio Mechanics

The game heavily emphasizes vocal interaction. Using proprietary V.O.I.C.E. technology, players talk into the Spirit Box using their own microphones. Entities, as well as the souls of their previous victims, possess distinct behavioral traits and respond dynamically to hundreds of phrases.

In multiplayer, players communicate using both local proximity voice chat (featuring room-based acoustics) and long-range walkie-talkies. However, entities actively listen to player audio, and loud communication can provoke violent responses, door slams, thrown objects, sanity loss, or physical attacks. Furthermore, the Spirit Box can be used by living teammates to communicate with fallen players who have turned into ghosts.

Base Management and Sanity

Surviving an excursion requires returning to the central facility to process gathered resources:

  • Daily Quotas: Players must fulfill a mandatory Enticine quota every 24 hours. Meeting quotas keeps the facility operational, while surplus energy goes toward powering the base.
  • Sanity Recovery: Cognitive strain, fear, and exhaustion are tracked via a persistent sanity value. To recover sanity, players return to their persistent personal cabins to rest, drink coffee, use the serenity chamber, or play mini-games like chess and basketball.
  • Upgrades & Crafting: Excess credits and power can be spent on crafting upgraded gear, personal perks, and purchasing up to 10 distinct base facility upgrades.
