Tokyo-based developer Gamincat is set to launch ERROR:Ai.lien, a bishoujo horror adventure game, on PC via Steam in 2026. The game features an AI girl named Airi who observes and learns from players, leading to a narrative that evolves from affection to dependence and madness. Players can advance through the story, engage in adventure segments, and revisit scenes for alternative routes. The game includes a Story Mode with visual novel mechanics and an Adventure Mode with item collection and movement controls. Mini-games include a fast-food job, balloon challenges, and "Old Maid." The initial playthrough lasts two to three hours, with subsequent playthroughs revealing new scenes. The soundtrack features an unsettling score, and the game includes full Japanese voice acting by Hiyori Kono.
