Currently in prototyping, Stolen Heart blends co-op roguelike action and rhythm gameplay: protect a living heart and resist the machines that have replaced humans in a dystopian laboratory. Every beat counts.

Stolen Heart is a cooperative roguelike where your mission (yes, you and your friends) is to protect… a living Heart, a fragile, unstable, essential being controlled by one of the players.Together, you’ll navigate a laboratory ruled by AI-driven robots (yes, we’re anti-AI in games, ironically), manage the Heart’s stress through a cooperative rhythm mechanic, and survive a dizzying descent toward the Earth’s core.Each run is a race against rising pressure, where coordination, timing, and trust decide whether you make it out alive. <img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/2617820/extras/bfe91d4db06b639d605a78cab4e79b24.avif?t=1772103885" width=1015 height=321 /><h2 class="bb_tag" >A Heart to Escort… and to Play</h2>The Heart isn’t an item, it’s a playable character: vulnerable, emotional, but crucial to the team thanks to its unique abilities.Protect it, sync with it, and keep its emotions under control: that’s the core of the gameplay.<h2 class="bb_tag" >A Unique Cooperative Rhythm System</h2>When the Heart gets stressed, its pulse spikes.Players must jump into a shared music-based mini-game:<ul class="bb_ul"><li>synchronize actions,</li><li>stabilize the heartbeat,</li><li>prevent a full-blown meltdown.</li></ul>Every beat matters, turning stress into a moment of collective tension.<h2 class="bb_tag" >An Intense Co-op Roguelike</h2><ul class="bb_ul"><li>Fast-paced combat mixing melee and ranged</li><li>4 complementary classes (Heart, Assassin, Inventor, Brute)</li><li>Essential team synergies</li><li>Varied upgrade trees &amp; choices every run</li><li>Procedural generation for endless replayability</li><li>A plunging descent deep beneath the Earth</li></ul><h2 class="bb_tag" >A Dystopian Descent Into the Earth’s Core</h2><img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/2617820/extras/c27a66f46ad922d131f695a23c7d2bea.avif?t=1772103885" width=334 height=251 />From sterile labs to organic caverns and finally the lush chambers of the planetary Heart, each biome tells the story of a world collapsing under its own AI systems.An atmosphere inspired by modern themes:<ul class="bb_ul"><li>technological responsibility,</li><li>preservation of life,</li><li>human resilience.</li></ul><h2 class="bb_tag" >Gameplay Built on Symbiosis</h2>You’re never alone: the Heart empowers you, and you protect the Heart.Every role counts, trust and coordination are everything.<h2 class="bb_tag" >Core Gameplay Loop</h2><ul class="bb_ul"><li>Explore and fight hostile AIs</li><li>Manage the Heart’s stress and pulse</li><li>Find oases to evolve and upgrade</li><li>Descend deeper and deeper</li><li>Try to reach the Sanctuary… before everything collapses</li></ul><h2 class="bb_tag" >Classes &amp; Skills</h2><video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/2617820/extras/e7f7de7cba617b611b7d17f14ae65cc5.poster.avif?t=1772103885" width=1170 height=522 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/2617820/extras/e7f7de7cba617b611b7d17f14ae65cc5.webm?t=1772103885" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/2617820/extras/e7f7de7cba617b611b7d17f14ae65cc5.mp4?t=1772103885" type="video/mp4"></video>Each class comes with:<ul class="bb_ul"><li>1 unique passive</li><li>3 major evolutions</li><li>Skills from Level 1 → 4</li><li>Build-shaping choices at every step</li></ul>Result: no two runs ever play the same.<img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/2617820/extras/af98511deedd69ffa8be5a41c670fc65.avif?t=1772103885" width=1015 height=321 /><ul class="bb_ul"><li>Hades: fluidity, builds, combat rhythm</li><li>Dungeon of the Endless / Endless Dungeon: escort mechanics &amp; constant danger</li><li>Ravenwatch / Risk of Rain 2:  skill-based co-op</li><li>FF Crystal Chronicles: guarding a shared core unit, reimagined for modern players</li></ul><h2 class="bb_tag" >Who Is Stolen Heart For?</h2>Perfect for players who love:<ul class="bb_ul"><li>demanding roguelikes,</li><li>co-op where every mistake matters,</li><li>synchronization-based gameplay that keeps everyone engaged,</li><li>shared tension and “DUDE WE ALMOST DIED, THAT WAS INSANE” moments.</li></ul>Ideal for duos or squads looking for a fun, challenging co-op experience.
