The Game at a Glance

What is That Which Remains?

That Which Remains is a one to four player sci-fi ghost-hunting horror extraction simulator developed by Remaining Games and published by Interdimensional Games Inc. Playing as Relics pulled from historical eras of human suffering, players work for the corporation Entitech in the year 2250 to harvest liquefied trauma called Enticine to power a future utopia.

During an excursion, players explore temporal contamination zones, locate hostile parasitic entities, gather evidence with specialized gear, and capture trauma fuel. After securing Enticine and salvage, teams extract back to a central base hub to meet an escalating daily quota, maintain persistent sanity, and spend surplus power on base upgrades and crafting.
