With Friend’s Pass, players who do not own Whisper Mountain Outbreak can join a friend’s lobby and experience the game in full co-op mode. They can also try out a limited version of the solo demo offline. This initiative is designed to make multiplayer more accessible and encourage players to experience the game’s cooperative elements.
To use Friend’s Pass, players must obtain a room code from someone who owns the full game, download the free Friend’s Pass version from Steam, and then connect to play the game together.
Whisper Mountain Outbreak is set to launch via Steam Early Access on 11 August 2025 at 2100 Western Indonesian Time (GMT+7). In the game, players take on the role of secret government agents tasked with investigating paranormal threats in the eerie, fog-covered Mount Bisik.
