Amsterdam, The Netherlands– JUNE 16, 2026 – KRAFTON, Inc. and ReLU Games Today announced the first major update for MIMESIS, the four-player co-op horror game from KRAFTON’s creative studio ReLU Games. Available now, the update improves the behavior and decision-making of the game’s AI-driven monster, known as the Mimesis, while also overhauling progression, rebalancing difficulty, expanding maps, and adding new gameplay systems.
MIMESIS is an AI-native co-op horror game where players work together to survive while trying to identify an AI-controlled entity hiding among them. The Mimesis mimics players’ voices, movements, and behavior in real time, secretly blending in with teammates and creating tension, distrust, and social deception as players try to determine who can be trusted.
Improved AI-Driven Monster Behavior
The update strengthens the core MIMESIS experience by making the Mimesis more natural, varied, and unpredictable. ReLU Games has refined the monster’s situational awareness, including how it recognizes its surroundings, approaches players, and reacts during gameplay.
Unlike enemies in many co-op horror games that follow fixed behavior patterns, the Mimesis learns from player voices and actions during each match. Each Mimesis now also has its own behavioral traits, meaning players can no longer rely on memorized patterns and must adapt to different forms of deception each time they play.
Overhauled Progression and Difficulty
The update also introduces a major progression overhaul. The previous three-day cycle has been replaced with a more flexible structure, and overall difficulty has been rebalanced to make the early game more approachable while increasing tension in later stages.
The goal is to reduce predictability across repeated playthroughs. New players should have a smoother entry point, while experienced players will face more varied situations that require different decisions, reactions, and team communication.
Expanded Maps, Monsters, and Gear
The first major update also expands MIMESIS with larger maps, new monsters, environmental devices, and gear upgrades. Factory, Subway Station, and Mansion dungeons now include new interior layouts, while Outdoor Areas have been redesigned with updated routes and layouts, giving players more variety as they explore, move, and scavenge for Scrap.
Players can also now throw Scrap, creating new strategic options during exploration and encounters. In addition, the spectating experience has been updated. After being eliminated, players can possess the monster that once threatened them and communicate with surviving teammates, helping keep eliminated players involved while maintaining tension throughout the match.
“MIMESIS has shown how AI can move beyond a development tool and become a central part of the gameplay experience itself,” said Min-jung Kim, CEO of ReLU Games. “With this update, we are continuing to explore how AI can reshape the conventions of co-op horror and create new kinds of player-driven tension, deception, and fun.”
MIMESIS has continued to build global momentum since launching in Early Access in October 2025, surpassing one million copies sold globally within 50 days. Earlier this month, the game became the first Korean original IP to receive an Excellence Award in the Game Design category at the CEDEC Awards 2026, hosted by CEDEC, Japan’s largest professional conference dedicated to game developers. The award recognized the creativity and technical execution behind the game’s AI-driven gameplay design.

About MIMESIS
MIMESIS is a four-player co-op horror psychological game in which players must face an AI entity, “Mimesis,” that behaves like a human player. Set in a world transformed by a mysterious rain that turns humans into “Mimesis” beings capable of replicating other people’s voices and actions, the game places players in an extreme situation where they must cooperate with teammates while never being able to fully trust one another. The game unfolds around a tram, and players must gather resources and work together to keep it running. At the same time, the constant possibility that one of their teammates may be revealed as a Mimesis shapes the experience throughout. Drawing on feedback accumulated through two rounds of testing and demos, ReLU Games has implemented a more refined AI-powered NPC, “Mimesis,” in the Early Access version. Players can experience deep immersion through the subtle tension created by the intersection of cooperation and suspicion.
