The official That Which Remains trailer introduces a sci-fi co-op ghost-hunting extraction sim developed by Remaining Games and published by Interdimensional Games Inc (iDGi). Revealed on September 28, 2026, the announcement footage establishes a dystopian premise where humanity's supposed utopia is powered entirely by liquefied trauma harvested from supernatural entities across space and time.
Below is a detailed breakdown of everything shown in the reveal trailer, the confirmed extraction mechanics, and what players can expect from the game's release.
What the That Which Remains Announcement Trailer Reveals
The announcement trailer opens with a corporate orientation message delivered to the player, addressed directly as a "Relic." The narrator explains that in the year ~2250 C.E., human civilization has supposedly eliminated war, scarcity, and death to create a perfect utopia. However, clean fusion energy is revealed to be a corporate lie. The entire society runs on a substance called "Enticine" (phonetically spoken as "antiseen" in the trailer briefing), which is pure, concentrated trauma harvested from catastrophic historical events across time.
Because a world without suffering cannot produce its own trauma fuel, the corporation known as Entitech resurrects "Relics"—individuals taken from long-dead historical eras marked by suffering. The trailer outlines the core mandate: players must venture into temporal contamination zones, locate hostile apparitions, extract their trauma, and return to base to fulfill strict daily corporate quotas.
The trailer transitions from this sinister onboarding pitch into raw in-game co-op gameplay:
- A squad of players explores a dimly lit, dilapidated residential structure.
- Players monitor high-tech investigative gear, shouting callouts as an EMF reader begins spiking rapidly.
- The squad pinpoints the apparition to a dining room, scrambling to take photographic evidence as the entity rapidly turns aggressive.
- Proximity voice chat captures frantic warnings from teammates yelling for everyone to run upstairs before the entity ambushes them from behind.
Core Gameplay Loop: Hunt, Identify, and Extract
According to developer details and the Steam store overview, That Which Remains combines atmospheric ghost-hunting investigation with survival extraction systems. Each excursion follows four distinct phases:
1. Hunt
Teams of one to four players enter contamination zones ranging from suburban houses to sprawling arctic prisons. Using roughly 18 different tools, players scan the environment for spectral clues, including:
- Electromagnetic field (EMF) spikes
- Sudden anomalous temperature spikes or drops
- Ghost orbs visible exclusively through camera lenses
- Telekinetic disturbances, flickering lights, shattered windows, and physical illusions
- Direct audio responses through the Spirit Box using V.O.I.C.E. speech recognition technology
2. Identify
There are 12 fully realized entity types planned for the initial launch pool. Each entity possesses distinct personalities, temperaments, and behavioral triggers. Players must cross-reference primary sensory evidence and secondary behavioral traits in their investigative log to correctly identify the apparition before it turns lethal.
3. Extract and Make Quota
Once identified, players deploy specialized capture equipment and traps to extract Enticine directly from the entity or recover trauma-laced artifacts across the site. At the conclusion of each excursion day, the extracted Enticine must be submitted to meet Entitech's rising daily quota. Surplus Enticine powers the squad's home base, while failing quota carries severe penalties.
4. Return to Base
Surviving players return to a persistent base hub. Sanity in That Which Remains functions as a cumulative metric reflecting fear, physical exhaustion, and cognitive strain. To regenerate sanity, players can sleep in their personal cabins, drink coffee, play mini-games like chess or basketball, or build high-tier facilities such as a serenity chamber. Players also spend earned Energy Credits to craft new gear, upgrade base power, and unlock character perks.
Key Features Highlighted in the Reveal
The reveal highlights several mechanics designed to separate the title from traditional ghost-hunting games:
- Dead Player Communication: The in-game Spirit Box is not just for speaking to entities and past victims. Fallen teammates can speak through the device to warn their surviving squad mates or feed them navigational callouts.
- Proximity Voice Chat and Room Acoustics: Sound propagation relies on realistic per-room audio acoustics. Players can switch to walkie-talkies for long-range team communication, but hostile entities can hear player voices and react accordingly.
- Continuous World: The game features an uninterrupted world without loading screens after the initial game boot.
- Weather and Time-of-Day Difficulty Modifiers: Dynamic weather patterns and a full 24-hour day/night cycle serve as active difficulty scaling systems, adjusting environmental hazards and completion rewards.
- Persistent Personal Cabins: Any cabin furniture and decorative elements customized by the player carry over between game sessions.
