Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Bone Stuff is built around an original core mechanic that we believe can create a fresh co-op experience. We want players to have fun with their friends, experiment with physics-based systems, and gradually become curious about the story behind the world they discover.

We chose Early Access because a game of this kind becomes stronger when real players interact with it in unexpected ways. Player feedback will help us understand which moments feel the most fun, which mechanics need to be expanded, how the story should be presented, and what kind of future content the community would like to see.

Our goal is to develop Bone Stuff together with the community by improving the gameplay, expanding the content, fixing bugs, enhancing balance, and shaping the full release based on real player feedback.

Approximately how long will this game be in Early Access?

“Approximately one and a half years of Early Access.

How is the full version planned to differ from the Early Access version?

“For the full release, we plan to expand the world of Bone Stuff with more story content, NPC-driven events, new quests, greater level variety, and deeper worldbuilding.

As the main story progresses, we want players to discover more about how other characters survive in the world of Bone Stuff and how they adapt to it. While the Early Access version focuses on the core gameplay experience, our goal is for the full release to offer a more complete, more polished, more stable, and more replayable experience.

We also plan to improve balancing, fix bugs, enhance the visual and audio experience, add quality-of-life improvements, and shape future content based on community feedback.

What is the current state of the Early Access version?

“The current Early Access version is playable and includes the core gameplay loop, available minigames, implemented systems, and the main features described in the “About This Game” section. Players can currently access the available content and experience the game as it is being developed.

The game is still in active development, so additional minigames, content, balancing, bug fixes, optimization, polish, UI/UX improvements, and quality-of-life updates are planned for future updates.

For a detailed overview of the content and features currently available, please refer to the “About This Game” section.

Will the game be priced differently during and after Early Access?

“We do not currently plan to change the price of the base game during Early Access or when the full version is released. Players who purchase the game during Early Access will keep access to the base game and its core content as the game continues to be updated.

Future updates may add new content, features, improvements, balancing changes, bug fixes, optimization, and polish to the base game, but our current plan is to keep the base game price the same during Early Access and at full release.

Optional DLC or separately released additional content may be priced separately in the future. If our pricing plans change, we will inform the community in advance.

How are you planning on involving the Community in your development process?

“We plan to involve the community in the development process through Steam discussions, Discord, player feedback, bug reports, and suggestions.

Feedback from players will guide us on balancing, bug fixes, new content, minigames, story presentation, and quality-of-life improvements.

Our goal is to use players’ experiences and suggestions to make Bone Stuff a more fun, more stable, and more replayable game.

About This Game

Hell has begun to seep into the world. A random group of 3–6 people find themselves in the wrong place, at the wrong time, and with far too many missing pieces.

You cannot get out of here alone.

You will need your friends’ hands, legs, heads, voices, and, more often than not, their terrible decisions. To escape Hell, you must work together, operate cursed machines, solve physics-based puzzles, run from creatures, and use your own body as a tool when necessary.

Lost an arm? Throw it.
No legs left? Let a friend carry you.
Only your head remains? Your voice may still be useful.
Trust your friends? Think again when the game reaches its end.

Story-Driven 3–6 Player Co-op Chaos

This is a story-driven online co-op adventure designed to be played with friends. Progress is not only about completing objectives; you must understand each other, carry each other, save each other, and sometimes accidentally sabotage each other.

Each level presents a different hellish system that your team must solve together. Sometimes you will need to distribute weight as a group to open a door. Sometimes you will need to use a friend’s limb. Sometimes everyone will do the wrong thing at the same time, and the entire team will fall apart. Literally.

Limb-Based Gameplay

Your character is not an ordinary hero. You are a skeleton that can break apart, rebuild itself, and use its own body as a tool.

Use your arms, legs, and head to solve puzzles, carry objects, activate mechanisms, or throw them at your friends. Replace missing parts from bone piles and rebuild your body for different situations.

In Hell, survival sometimes means giving up a piece of yourself.

Physics-Based Puzzles

Hell is not fair, but it does have mechanics.

To progress through levels filled with pulleys, valves, weights, pressure systems, gases, liquids, conveyor belts, explosives, and strange machines, your team will need to think together. One small mistake can punish the entire group, while a well-timed sacrifice can save everyone.

Some puzzles are powered by voice. Use helium to make your voice higher, sulfur to make it deeper, and work together to open doors, match rhythms, or accidentally summon something much worse.

A Hell Full of Dark Humor

This place is not just lava, chains, and demons.

Hell is filled with skeleton towns, bizarre courts, bone shops, cursed cafés, useless NPCs, talking corpses, and punishments that feel uncomfortably personal. Every character may have an absurd, dark, and disturbingly funny story about why they ended up here.

The tone shifts between horror and comedy. One moment, you are trying to save your friend from a creature. The next, you realize you accidentally left their head in front of a door.

Trust and Betrayal

At the beginning, everyone is on the same side.

To survive, you must work as a team. You carry each other, save each other, share body parts, and open paths together. But as the exit from Hell gets closer, everything begins to change.

It is not clear whether everyone can be saved. Good decisions, bad sacrifices, and broken trust will determine the ending. Without your friends, you are nothing. But when the final gate opens, you may no longer be sure whether your friends are still your friends.
