Face the Curse, Complete the Mission. Whisper Mountain Outbreak’s Cursed Update Is Here!

The Cursed Update, the latest and most nightmarish content addition yet to Whisper Mountain Outbreak, is here! Get together with your friends again to face more frightening enemies, nerve-wracking puzzles, exciting new skills, and - as the title suggests - the addition of cursed items.

The cursed items will require you to be more aware of your surroundings and coordinate better with your team. You WILL encounter the curse, and you need to get out alive with it!

This update marks another major milestone in Early Access, redefining the core experience with several additions and improvements. It is also available for both the full game and the Friend’s Pass version.

New Features Highlight

New Map Modifiers

Mission now features additional map modifiers that add more challenges and require agents to adapt.

  • Cursed items - A dark curse may now afflict key items. Carrying them in your inventory will grant negative effects to the holder, such as health drain, disorientation, and blindness.

  • Additional modifiers: toxic enemies and exploding zombies.

Class rework

All playable classes have been reworked to define their roles better and improve overall team synergy. Each class now offers clearer strengths, more impactful perks, and a stronger identity during missions.

  • Bodybuilder - They now have more maximum life & can ram enemies while dashing, but have a slower sprinting speed.

  • Medic - Can heal a critically wounded teammate and craft a DIY aid kit from the beginning.

  • Firefighter - Starts with an axe and can craft it early. Resistant to blast damage, yet struggles with firearm accuracy.

  • Rookie Agent - Armed with a Pistol attached with High-Caliber Barrel and can craft more early on. Poorly trained in melee combat.

  • Security Guard - Reduces physical damage taken from enemy attacks and consumes less stamina when performing melee attacks.

  • New Map: Commercial Area

    • The Commercial Area is a dense district filled with convenience stores, gas stations, and small shops. Blood-red roots creep across walls and roads, slowly consuming what remains of the area.

  • New Puzzles

    • Four new mind-bending puzzles are now available for you to solve!

  • New Elite Boss - Alpha Hollow Mother

    • A far more terrifying variant of the already dangerous Hollow Mother has emerged in the Abandoned Factory map. To obtain the final artifact, players must face and defeat this monstrous entity.

  • Safehouse Map Update

    • This location will now appear after players complete the mission in City Hospital and will no longer be an endless mission.

  • New Cutscene

    • A new cutscene has been added to serve as a conclusion for the currently available missions during Early Access.

  • Cats!

    • Stray cats can now be found wandering in certain areas of the map. You can interact and pet them.

  • Bug Fixes

    • Door bug, where, after solving a puzzle, the rolling door would open for the host but not for the clients, is now fixed. Connection issue where items could become unsynchronized after a player reconnected to a session is also fixed.
