ReLU Games, a creative studio under KRAFTON, Inc., has officially revealed that their psychological horror co-op title MIMESIS will launch into Early Access on October 27, 2025. The studio also released a new Early Access trailer and opened signups for the final Closed Beta Test.
In MIMESIS, a mysterious rain causes afflicted humans to transform into creatures called “Mimesis,” which mimic the voices, behaviors, and memories of others. Players must cooperate to escape via a tram, gather vital resources, and keep the vehicle running—while paranoia builds, because one of your teammates might already be an impostor.



The Early Access version will expand on the base experience with new maps, monsters, and resource mechanics (called Scrap). It will also feature enhanced cooperative systems and increased survival tension built around trust and deception.



Before launch, ReLU Games will hold a final Closed Beta Test (CBT) from October 10 to October 13, letting select players test refinements and stability. Community events like localization challenges and creator initiatives will also run to engage fans and polish the game before Early Access begins.
