That Which Remains is a sci-fi ghost-hunting horror extraction simulation available in Early Access on PC. Set in the year 2250, the game places players in the role of Relics, individuals pulled from a past era of suffering to harvest liquefied trauma known as Enticine from invasive entities called Neurospatial Parasitic Entities, or ghosts. These beings thrive on human trauma in a world that has otherwise eliminated war, scarcity, and death. The core experience blends action, simulation, and indie horror elements in a cooperative setup supporting one to four players, with proximity voice chat adding tension as entities listen in on conversations.
Gameplay
The gameplay centers on exploring contamination zones haunted by residual trauma. Players search for evidence of entities using tools that detect EMF signals, temperature anomalies, ghost orbs visible only through cameras, telekinesis effects, and other signs. The V.O.I.C.E. technology allows direct interaction via the Spirit Box, where spoken words can elicit responses from the entity or its captured victims, each with distinct personalities. A walkie-talkie supports team coordination while proximity chat handles close-range talk, though the entity remains aware of all audio.
Entities exhibit varied behaviors, including possession, door slamming, object hurling, light manipulation, window shattering, and manifestations involving fire or electricity. These actions erode player sanity, a persistent stat that combines exhaustion, fear, and cognitive strain. Weather and time of day influence difficulty and potential rewards during excursions. Identification involves mapping signature evidence or noting secondary traits and personalities across twelve entity types, with details recorded in a log for pattern recognition over time.
Extraction follows identification, using traps or a capture tool to pull Enticine directly from the manifested entity. Players must meet daily quotas, with surplus contributing to base power. Failure risks base shutdown and its consequences. Back at base, sanity recovery comes through cabin rest, coffee, basketball, chess, or the serenity chamber upgrade. Energy Credits fund tool crafting, while Base Power supports upgrades and unlocks for equipment and personal improvements. The cabin and its decorations persist across sessions in a continuous world without loading screens after launch.
Game Modes
The primary experience revolves around coordinated extraction runs in contamination zones. Teams hunt for entities, gather evidence, identify the threat, extract resources, and return safely before the day cycle ends. Dynamic weather and a 24-hour day-night cycle alter each outing, affecting visibility, entity activity, and rewards. Full-body awareness ensures other players see actions like tool use or movement in real time, enhancing immersion during group play.
Base management serves as the persistent hub between runs. Players upgrade facilities, craft items, and level up for new equipment and personal enhancements. The system encourages repeated excursions to sustain power and progress, with unique decorations traveling between sessions. Proximity voice chat and per-room acoustics heighten the horror during both exploration and base downtime when entities might interfere.
Key Features and Systems
Five contamination zones provide distinct environments for exploration, each with its own stories and entity encounters. Approximately eighteen tools support evidence gathering and extraction, with more planned. The experience and level system ties directly to upgrades, rewarding successful quotas and efficient runs. Twelve fully realized entities offer diverse abilities, moods, and reactions to player actions or spoken words, creating varied challenges across sessions.
Sanity management integrates into every phase, from zone exploration to base recovery activities. The continuous world design supports seamless transitions, while the simulation aspects extend to base power maintenance and resource allocation. These elements combine action-oriented entity confrontations with methodical identification and extraction in a multiplayer framework.
Is It Worth Playing?
That Which Remains suits players who enjoy cooperative horror experiences with voice chat mechanics, extraction loops, and base-building progression. The blend of ghost-hunting investigation, entity interaction through voice tools, and persistent base upgrades creates a focused loop for those interested in sci-fi horror simulations. Early Access status means the game continues to evolve with additional entities, tools, and zones in development. Fans of small-team coordination under pressure and detailed evidence-gathering systems will find the core systems engaging, particularly when proximity chat heightens the risk of entity detection. The emphasis on personality-driven entity responses and sanity tracking adds depth for repeated play.
