About This Game

Whisper Mountain Outbreak is an isometric co-op PvE multiplayer survival horror game where you and your friends must work together to escape the cursed fog-covered Mt. Bisik.

Explore abandoned buildings, fight monsters, scavenge resources, craft items, solve puzzles, and figure out a way to escape the whispering madness.

STORY

It’s 1998; a mining operation on Mt. Bisik inadvertently unleashed an ancient horror when they disturbed a ruin buried deep inside the mountain.

People started hearing whispers and seeing monsters when a mysterious fog suddenly appeared and covered the area surrounding the mountain. Now, you and your friends are trapped in the cursed Mt. Bisik.
