In a move that’s got fans of the retro-futuristic shooter buzzing, Mundfish has unveiled the gameplay trailer for Atomic Heart’s fourth and final DLC, Blood on Crystal. This marks the thrilling conclusion to the first chapter of the game’s wild storyline, promising high-stakes action, grotesque new foes, and a bloody showdown that ties up loose ends ahead of Atomic Heart 2. The trailer, which dropped on March 5, 2026 clocks in at just over a minute and a half of pure chaos.
Blood on Crystal picks up where prior DLCs left off, thrusting P-3 and his AI companion, the Twin, deeper into the bowels of Facility 3826. Their mission? A desperate assault on the classified Crystal Complex and Wave Platform to confront the enigmatic CHAR-les, the robotic overlord whose nefarious experiments threaten total human annihilation. Players will unearth the horrifying truth behind CHAR-les’ plans, battling through new, otherworldly locales in a race to save what’s left of the utopian Soviet sci-fi world gone mad. This DLC serves as the definitive end to Atomic Heart’s “Part 1” narrative arc, wrapping up the core story while teasing the larger universe that Mundfish is expanding with Atomic Heart 2 and the multiplayer shooter The CUBE.
Expect to adapt on the fly against Polymorphs, CHAR-les’ twisted spawn that shapeshift into fire, ice and lightning, demanding players switch up weapons and glove powers mid-fight. The trailer teases the “most insane bosses” yet, with hulking mechs and polymorphic horrors that push P-3’s combat toolkit to its limits. Mundfish promises integration of gear from previous DLCs, ensuring a symphony of guns, polymers, and brutal melee for veteran agents.
Blood on Crystal launches on April 16, 2026 across PS4, PS5, Xbox One, Xbox Series X|S, and PC.

Atomic Heart’s DLC saga has been a rollercoaster of absurdity and action, and Blood on Crystal looks set to deliver the bloodiest, most explosive finale yet. Whether you’re revisiting Facility 3826 or jumping in fresh, mark your calendars—humanity’s fate (and P-3’s) hangs in the balance. Comrades, prepare your polymers! The revolution ends April 16.
