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.
