Set during the Cold War, The Outlast Trials casts players as prisoners subjected to the Murkoff Corporation’s experiments in brainwashing and mind control. Its horror premise frames each outing as a test of endurance and survival, with disturbing tasks standing between patients and the chance to leave the facility.
The central challenge is evasion rather than combat: players avoid enemies, hide, or run, while earned tools can help them stay stealthy or create an escape. The game separates its activities into story-driven Trials and shorter MK-Challenges set in altered sections of existing maps. Players can also customize a patient and choose tools, upgrades, and perks to suit their preferred approach.
The game supports solo play as well as cooperative teams, with cooperation optional for mandatory objectives. A count therefore reflects activity around a game that can be approached alone or shared with others, across both longer Trials and shorter challenges, rather than a title limited to one party format.
