About Whisper Mountain Outbreak

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.

FEATURES

  • Survive and fight the horde
    Monsters will come in waves. Fight them off using a variety of melee and ranged weapons, use herbs to recover your health, and protect each other’s backs!
  • Co-op multiplayer madness
    Teamwork is key in this race to safety. Communicate using in-game proximity voice chat, save downed teammates, and share the scarce resources you find.
  • Explore, solve puzzles, and find a way to escape... together!
    Work together to solve puzzles, find keys, unlock doors, and figure out a way to escape the curse.
  • Learn new skills and craft items
    Turn your hard-earned experience and resources to tackle harder missions by utilizing your newly learned skills and crafted items.
  • 2.5D retro graphics with a claustrophobic, dark, and creepy atmosphere
    A lingering fog, tight rooms, limited visibility, and eerie whispers, presented in 2D pixel characters with 3D low-poly environments. Offering both nostalgic and freshly terrifying experiences.
  • Choose your specialization
    At the start of each run, choose from three random classes (out of six total). Each class has unique perks and skills, allowing for different playstyles and strategies.

crashes at least once per session. if your session crashes, you will crash on that save every time and can't complete the level. you have to delete the save...also friend pass players lose their stuff if they crash or you don't finish the run in the same playthrough

A roguelike 2.5D Isometric Resident Evilesque shooter. You will die trying to figure out the gameplay loop and puzzles, but it's a lot of fun trying to figure it out. Highly reccomend.

Bought this and played for a moment. They nailed the ambient like Valve did with Left for Dead, but the sounds of the zombie is kinda irritating me for i don't know the reason. Too scared to play alone, if someone want to play together, add me :'D
