Description

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

Explore abandoned buildings, fight monsters, scavenge resources, craft items, solve puzzles, and figure out a way to destroy the evil lurking beneath the shroud.

The Story of The Game

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, it is your duty as an agent of BRIM (Bureau of Research & Investigation of Metaphysics) to investigate and eradicate the paranormal and otherworldly threats.

History

In the early 2000s, Capcom released Resident Evil Outbreak, a survival horror game with online playability. It was one of the first survival horror games to feature cooperative gameplay, the game was groundbreaking. Sadly, it was released too far ahead of its time, and the game was a commercial flop.

For 20 years, fans of the Resident Evil franchise have waited for Outbreak to be revived or remade. Fans wanted the Resident Evil style survival horror experience, such as solving puzzles and surviving the zombie apocalypse with limited resources, together with their friends. Unfortunately, Capcom had other plans, they kept releasing online multiplayer Resident Evil games, but without the survival horror, instead, they released arcade team-based action shooters which the fans hated.

Many of Toge Productions crew members are big fans of survival horror games, including the studio’s founder and CEO, Kris Antoni, who is a big fan of Resident Evil and Silent Hill. We were all tired of waiting for Capcom to remake Resident Evil Outbreak, so we decided to make our own coop survival horror game. The planning for Whisper Mountain Outbreak started in around 2021.
