Mimesis is in early access on Steam with a 'Very Positive' rating from over 7,000 user reviews, and received a major June 2026 update that overhauled AI monster behavior and game structure.
Mimesis, a cooperative survival horror game developed by ReLU Games and published by KRAFTON JAPAN, entered early access on Steam in October 2025. By June 2026, the game had accumulated over 7,000 user reviews and maintained a 'Very Positive' rating. In early June, the game won the Excellence Award in the Game Design category at CEDEC Award 2026, and was also a finalist for the Grand Prize. The selection committee praised its AI-driven NPC that mimics player voices and actions, creating tension and unpredictability.
On June 16, 2026, KRAFTON JAPAN released a major update that improved the AI-driven monster's decision-making, added individual monster personalities, revised the game's progression from fixed 3-day cycles to a flexible structure, expanded dungeon interiors, and revamped the spectator system to let eliminated players possess monsters. The update moved the game away from memorization-based play toward adaptive strategy.
Two days later, on June 18, 2026, ReLU Games launched a 30% off sale on Steam, dropping the price to 840 yen until June 25. That same day, KRAFTON JAPAN began the KRAFTON Steam Publisher Sale 2026, which included Mimesis among over 30 titles from KRAFTON and its studios, running from June 18 to June 26. The game's inclusion in both sales and the recent content update suggests active development continues.
