肝試しオンライン is a multiplayer horror game for PC that blends social deduction, proximity voice chat, and streaming mechanics in a Showa-era junior high school setting. Players form groups of four to eight friends who enter the abandoned building at night to film paranormal activity and grow their channels through viewer engagement. The core loop centers on exploration, tension from potential scares, and the constant risk that one or more companions may not be what they seem.
Gameplay
Each session begins with a short preparation phase followed by ten minutes of exploration. All participants act as streamers equipped with cameras to capture ghostly phenomena, with the intensity of recorded events directly boosting channel growth and subscriber counts. The school environment features randomized layouts and item placements across rounds, ensuring no two visits feel identical. Proximity-based voice chat forms a key system, where sound muffles through walls and fades across floors, forcing players to stay close or risk losing communication entirely. Traitors, numbering one to three and selected by the host, blend in with the group while gaining abilities to phase through walls and deploy disruptive traps that interfere with filming efforts. A voting mechanic allows the majority to identify and neutralize a suspected traitor by rendering their disruptive actions ineffective.
Game Modes
The game operates around a single primary experience focused on group exploration and traitor interference within the haunted school. Host settings adjust the number of traitors from one to three, creating variations in paranoia and strategy without introducing separate named modes. Sessions emphasize cooperative filming among most players while the traitor element introduces asymmetric disruption, all measured by in-game channel metrics rather than traditional victory conditions. No win or loss states exist; progress ties solely to subscriber gains from effective streams.
Core Mechanics and Features
Randomized school layouts keep repeated play fresh, with classrooms and items shifting each time to alter navigation and hiding spots. Streaming integration encourages players to treat every round as content creation, rewarding dramatic reactions and successful captures. The absence of traditional objectives shifts focus to survival, discovery, and social interaction through voice chat. Traitor abilities add layers of deception, requiring constant awareness of group dynamics and positioning. These elements combine action-oriented movement with strategic decision-making around trust and communication.
Is It Worth Playing?
肝試しオンライン targets groups who enjoy voice-chat-driven horror with social deduction elements, particularly those interested in creating shareable clips and streams. Its upcoming release in late October 2026 positions it as a fresh entry in the indie multiplayer horror space, built explicitly around repeatable sessions with friends. The randomized environments and proximity audio create genuine tension, while the traitor system adds replayability through shifting alliances. Players seeking casual yet strategic sessions without competitive rankings will find the subscriber-focused progression appealing. Those who prefer structured objectives or solo play may want to wait for post-launch feedback once the game becomes available on Steam.
