Enter Mt. Bisik's Horror, Co‑op Only Gets Stronger

Set in 1998, a mining operation awakens an ancient curse on Mt. Bisik. A mysterious fog brings whispers and monsters, trapping you and your team inside.

Together with up to four players, you’ll:

  • Fight off waves of terrifying creatures. Armed with melee and ranged weapons, herbs, and teamwork.

  • Solve environmental puzzles. Unlock doors, find keys, and piece together the curse’s secrets.

  • Scale your abilities. Choose from six agent classes each run, progress skills, craft items, and adapt to mounting threats.

  • Explore tense and claustrophobic terrain. Fog shrouded rooms, limited visibility, and eerie pixel art visuals mixed with 3D environments build constant tension.
