KRAFTON JAPAN released a major update for the co-op horror game Mimesis on June 16, 2026. The update improves the AI-driven monster's decision-making, adds individual monster personalities, revises the game's progression from fixed 3-day cycles to a flexible structure, expands dungeon interiors, and revamps the spectator system to let eliminated players possess monsters.
The AI monster in Mimesis now learns from in-game audio and player actions to recognize situations, evolving its approach timing and behavior patterns to be more natural and diverse. Individual monsters have distinct personalities, so the same monster type can behave differently across encounters. The game's progression structure has changed from fixed 3-day cycles to a flexible system with adjusted difficulty balance, making early stages easier for newcomers while increasing tension toward the end.
Factory, subway station, and mansion dungeon interiors have been expanded, and outdoor area layouts and movement routes redesigned. New monsters, environmental gimmicks, and equipment enhancement functions have been added, along with a resource-throwing mechanic. The spectator system now lets eliminated players possess monsters and communicate with surviving teammates.
