You wake up again. Your bones soaked in blood.

🩸 Wake Up. Die. Remember.

Heart of Bone is a 2D action-horror roguelite where every run is a fight for answers and a call for blood. Tommy awakens in a place where shadows breathe, and walls whisper. Survival is no longer his only goal—his shattered memories haunt him more with each failed escape. A voice echoes in his head, pulling him into deeper, more sinister darkness. It has awakened him through rage and trauma, to realize one single truth... this never-ending nightmare is about to be ripped to pieces!

You've been taken to the limits of your sanity, and there's no other option but to come back to life and figure out how not to die again. These things deserve nothing but revenge!

💀 Tear the Facility Apart

Slash through grotesque creatures, tear down walls, wreak havoc through the facility, and uncover the horrifying truth buried beneath the labs or at the top of the scientific food chain nestled with insanity. Each room drags you deeper into a nightmare: escalating rewards to face more ferocious and cunning enemies. Secrets and creatures waiting in the dark. Death repeats the cycle—but knowledge, skills, and her voice grow stronger.

Progression is constant and explosive. Tons of enemy types, abilities, weapons, and rooms mean no two descents unfold the same way. Whether you're facing mind-breaking horrors mid-playthrough or you feel untouchable, you can never predict what's waiting in the next room to shift your playstyle entirely.

🧬 Twist Your Body Into a Weapon

Experiment after experiment, death after death: mutate weapons, unlock grotesque bio-abilities, and twist Tommy's very body into a weapon of vengeance and truth. Progress through a skill tree that evolves with every run, giving you new ways to adapt your playstyle and specialize your build.

⚰️ One Truth. Many Endings.

Through a mind-bending setting and a story of multiple endings and branching paths, you'll experience every bit of hope and sorrow, every trap, every brutal death by even more brutal bosses. Though in your heart which still beats, you know there's only one truth, and you'll use every bone in your body to reach it.

After hundreds of trials and failed escapes, you now hear the voice through the gurgling of blood and the layers of dead flesh. Do you follow it? Do you give in to your rage and vengeance? Escape? Fall into the deep madness and horror of this place?

Tommy might have truly awoken, but the real nightmare has only just begun.
