About this game

MANNEQUIN SYNDROME IS BEING REWORKED

Mannequin Syndrome is currently undergoing a major redevelopment.

The game is being rebuilt with a new visual direction, redesigned gameplay systems, improved mechanics, new environments, and a completely reworked overall experience.

The overall direction of the game is also evolving. Mannequin Syndrome is shifting from a primarily horror-focused experience toward a more action-oriented game while still retaining its unsettling atmosphere, tension, mystery, and horror elements.

A large amount of development work is still ahead. The current version represents an early stage of this new direction, and many features, mechanics, animations, sounds, environments, and story elements are still being created or improved.

More details will be shared as development continues.

EARLY PUBLIC BETA

An early Public Beta version of the new Mannequin Syndrome is now available.

This release allows players to experience and test the current foundation of the redesigned game while development continues.

CURRENTLY AVAILABLE

The Public Beta currently includes:

  • Two playable multiplayer modes

  • King of the Hill

  • Containment — a cooperative wave-based mode

  • A playable tutorial level

  • Redesigned menus and user interface

  • Early versions of the new gameplay mechanics

  • Multiplayer support for playing with friends

  • A first look at the game's new action-focused direction

Invite your friends, try the available modes, and help test the current version of the game.

Bug reports, feedback, balancing suggestions, and ideas are highly appreciated and will help improve future updates.

CURRENTLY IN DEVELOPMENT

The main story campaign is still in active development.

The story mode is being designed as an action-horror experience, combining combat, exploration, environmental tension, mystery, and horror elements.

A large amount of work is currently focused on:

  • Story and mission design

  • Level design and environment creation

  • New 3D models and game assets

  • Improved animations

  • Combat and gameplay mechanics

  • Player interactions

  • Enemy behaviour

  • Sound design

  • Additional multiplayer maps

  • Improvements to existing game modes

  • Visual, performance, and usability improvements

The Public Beta does not represent the final quality, amount of content, or complete vision of the game.

IMPORTANT BETA INFORMATION

As an early Public Beta, the game may contain:

  • Bugs and technical issues

  • Unfinished or temporary mechanics

  • Missing content

  • Placeholder assets

  • Animation or sound issues

  • Performance problems

  • Balancing issues

  • Features that may significantly change in future updates

Development is ongoing, and future updates will gradually expand the game, improve its systems, and introduce more of the new action-horror direction.

Stay tuned for future updates!

    Behind the screen [Dev Updates]

    Its been a while since my last appearance here... As everyone I had busy times in my life but I do find time to continue on development of new version and I could say that its going pretty well. Level is still in progress as it requires tons of works, since also aligning and joining many areas properly, modeling everything and much more having a global headache with that tbh and a lot.But what actually is happening and where am I now with the development? First proper Character designs are modeled and animated properly to have on next major update first 2 playable characters fully. A lot of polishing happening with all the current things in the game like: - Tutorial level is being updated, no longer looks like an empty corridors and just rooms. - Main menu updated with better visual effects and changed namings (Extra modes covers multiplayer browser and hosting sessions, including 2 modes), Story is set to go solo or coop. - Waves mode receives improvement with actual objective what to do there (You will have secure Neural Core and neutralize mannequins... Repair it and continue... Survive as long as you can) - KOTH mode receives several types of difficulty. - Whole game visual being updated that main view reminds a bit of retro style graphics, which kinda looks pretty interesting ngl. - Additionally First Person view is also coming. - More interesting effects coming to Multiplayer modes, like neutralizing mannequin, it will burn and disappear. Being caught new effects and etc. A lot of bugs fixed, improvements, new approaches and much more are being in works also. I still don't want to promise that tomorrow or in a week I will finally publish the new update, but just wanna let you all know, that the progress is not abandoned and is being continued to improve and fix. Stay tune, join discord to keep up-to-date, as there I'm a bit more active to drop some information on what is going on. Till the next time ... ETA .... xx Days :)

    What if I will give you Public Beta release?

    Hello everyone! I'm still in progress with overhaul, but I'm starting to think to replace the old bad game version with new... But it would be as Beta version basically, since the game is still free to play there is nothing to lose right? But you would get access for new version and all its new content. Currently the version does not have any of the main story part (no levels) as its still in development and modeling. Currently the game has 2 pvp modes where you can play with friends and have fun: - King Of The Hill - fight for the crown and have fun with friends by pushing around! - Waves mode (Containment) - stay alive with the friends as long as you can! The game is still in progress and might have bugs which is fully normal for the current state, the game will be receiving updates and changes with improvements, the only thing which would be really nice to get feedback on what improvements and what bugs are found. If this fits you as the old version is broken and not properly playable, its better to change to the new approach and keep it Beta public release. What is currently now in the game: - Tutorial level : - PvP modes in multiplayer (king of the hill and containment) : ## King Of The Hill maps: Containment (Currently set as low poly fun map) where you have to stay alive during the waves of mannequins, as you will find EMP guns on the car nearby, to shoot the mannequins! I know the Current live build is broken and brings no interest.. So I think Beta Public release will change the approach, which brings way more different mechanics, additional playable mods and new future updates! Drop a comment if you are up for that and I will publish the Beta!
