About this game
Bone Stuff is a story-driven online co-op adventure game for 2–6 players. As breakable skeletons trapped in hell, you try to escape by using your bodies, your friends, and your bad decisions.
In each chapter, you encounter a new infernal order, a new strange character, and a new clue about why this world does not seem to want to let you go. As the story progresses, you begin to question not only the way out, but also what you are really doing here.
Losing your arms, legs, or head is not always bad news. Sometimes they become a key, a weight, a distraction, or the most important part of the plan your friend just came up with.
Solve physics-based puzzles, activate cursed machines, carry each other, collect your body parts, and choose the right person to blame when everything goes wrong.
To escape hell, you need to work together.
But as the story unfolds, one thing becomes clear:
You may not have ended up here by accident.
Open the valves, activate the mechanisms, and try to turn hell’s broken system to your advantage.
Remove your feet and climb up through hell’s vertical passages.
Engage in physics-based fights against giant creatures; dodge at the right moment, get thrown around at the wrong one, and try to survive without losing your parts.
Add Bone Stuff to your wishlist and reserve your place in hell.
