Atomic Heart Stories

Atomic Heart is Mundfish's 2023 shooter set in an alternate 1955 Soviet Union where a miracle substance called Polymer gave the USSR flying cities, household robots, and a neural network that links every mind in the country. Then the robots turned on everyone at Facility 3826, and you spend the game as Major P-3, a hot-headed KGB officer with a talking glove named CHAR-les, cutting your way through chrome killers and mutant lab experiments. On paper that's a horror premise. In practice the game is already one of the horniest things to come out of a major studio: the Twins, Left and Right, are two silent ballerina robots with mirror-polished bodies and a habit of pinning you to the floor; Nora is a refrigerator that moans and begs you to fill her; Granny Zina is a chain-smoking pensioner who turns out to be the most capable person in the whole disaster. Fans didn't have to invent the kink. They just followed it home.

The Twins are the center of gravity here, and most writers go one of two ways with them. Either they're dominant, wordless, and overwhelming, using that dancer's strength to hold a human down and take what they want as a pair, or they're written as awakening, curious about sensation, learning what a warm body feels like against cold polymer. Robot-on-human is the core dynamic, and it ranges from tender first contact to full dubcon with a Polymer-drugged victim who can't decide if they want to run. Nora gets a surprising amount of love, usually played for filthy comedy. Beyond the machines, readers come for uniform kink, sweaty survival hookups in a dark Vavilov lab, mind-control through the Kollektiv network, and P-3 getting talked through it by a glove that never shuts up. Sechenov's compound is a gift for power-imbalance scenarios: scientists, soldiers, experiments, locked doors.

This hub is brand new, so there aren't public stories tagged yet. As writers post, this is where you'll find them: anything set in Facility 3826, Chelomey, or the wider Soviet retrofuture, with the game's characters, its robots, or original ones dropped into the same world. If you've got an Atomic Heart story sitting in a drafts folder, this is the page it belongs on.

Can't wait for someone else to write the Twins scene you've been picturing? RedQuill lets you generate your own Atomic Heart story: pick the characters, set the scene in the ballet hall or the Polymer vats, and get exactly the version you want.

Atomic Heart FAQ

Atomic Heart fanfiction is fan-written stories set in the world of Mundfish's 2023 game, an alternate 1955 Soviet Union where robots and Polymer technology have gone murderously wrong. On RedQuill it means explicit stories about the Twins, Nora, P-3, CHAR-les, Granny Zina, and the staff of Facility 3826. Most of it leans into robot-on-human sex, dubcon, and power imbalance, though plenty of writers keep the game's dark humor and banter intact.

Because the game is already sexual and barely hides it. The Twins are graceful, silent, chrome-bodied robots who physically overpower you; Nora the fridge moans and begs; P-3 swears constantly and takes it all in stride. That mix of cold machines and hot, sweaty humans is a natural setup for erotica, and the retrofuturist Soviet aesthetic gives it a look and mood nothing else has.

The Twins, Left and Right, are two identical ballerina robots who serve as Dr. Sechenov's bodyguards and are the game's most recognizable characters. They never speak, move like dancers, and can pin a grown man in a second. That combination of beauty, strength, and silence makes them ideal for domination, threesome, and dubcon stories, which is why they dominate this category.

No. Robot-on-human is the biggest draw, but the category also covers human pairings and original characters in the same setting. Writers use the KGB uniforms, the isolated labs, the Kollektiv mind network, and Polymer experiments for scenarios about control, survival, and interrogation. Granny Zina, P-3, and Facility scientists all show up without a single machine involved.
