What Is Included in That Which Remains?
That Which Remains blends cooperative paranormal investigation with extraction simulation. Set around 2250 C.E., human civilization runs on a substance known as Enticine—liquefied trauma harvested from Neurospatial Parasitic Entities (ghosts). Players assume the role of "Relics," survivors abducted from past eras and conscripted by the Entitech corporation to extract trauma fuel across time and space.
The core gameplay loop and systems available across the project builds include:
- Team Setup: Playable solo or in online co-op for up to 4 players, featuring in-game proximity voice chat with per-room acoustics and walkie-talkies.
- V.O.I.C.E. Technology: Players can speak aloud into the Spirit Box to interact directly with hostile entities, trapped victims, or fallen teammates who communicate from beyond death.
- Investigation Mechanics: Track supernatural traces using roughly 18 dedicated tools, including EMF detectors, thermal sensors, and camera lenses that reveal ghost orbs.
- Entity Identification: Identify 12 to 13 distinct entity types by analyzing physical evidence, behavioral patterns, and mood reactions. Entities can violently manipulate the environment by shattering furniture, slamming doors, throwing items, cutting lights, and attempting possession.
- Extraction and Quotas: Trap or extract Enticine directly from confirmed entities, then deliver the required quota before the daily deadline. Surplus power feeds back into your base station.
- Base Hub and Sanity: Between excursions, players return to a central hub to recharge sanity through sleep, coffee, or serenity chambers. Base power and energy credits can be spent on crafting tools, upgrading facilities, and customizing personal cabins.
- Dynamic Conditions: Excursions feature a 24-hour day-and-night cycle alongside shifting weather conditions that scale both operational difficulty and resource rewards.
