Operation Bounce House (2026), by Matt Dinniman, is a darkly satirical stand-alone science fiction novel in the GameLit subgenre. In it, protagonist Oliver Lewis leads a fight to save the planet of New Senora from an attempted genocide orchestrated by a gaming company that is using its player-customers as remote mercenaries for Earth’s government. The novel critiques The Gamification of War and The Toxicity of Online Culture and examines the complex relationship between In-Group/Out-Group Dynamics, Colonization, and Genocide.

Dinniman has written many previous GameLit books, including the popular Dungeon Crawler Carl series, which is being developed into an NBCUniversal television show.

Plot Summary

Twenty-five-year-old Oliver Lewis, a farmer on the colony planet New Senora, is attacked by a remotely piloted robot called a “mech” while he’s out looking for one of his farm’s drones, called “honeybees.” His artificially intelligent (AI) drone, Roger, tells him to run home. At his farm, he; his 23-year-old sister, Lulu Lewis; and some elderly neighbors watch a feed from Earth and see commercials for “Operation Bounce House.”

This operation is being conducted by Apex Industries, a mercenary corporation run by Eli Opel, the former head of a gaming company. Earth’s government, the Republic, claims that New Sonora is overrun by terrorists. The Republic, whose real motive is to eliminate the colonists and seize their land, is paying Apex to kill most of New Sonora’s population. Above New Senora, Apex is orbiting in a ship where an army of mechs is being printed. Apex’s customers are paying to remotely pilot these mechs. The operation is supposed to last for five days, and the first large wave of mechs is scheduled to arrive in seven hours.

Roger sends Oliver; Lulu; Oliver’s girlfriend, Rosita Zapatero; and Oliver’s friends and bandmates, Sam Amboya, Tito, and Axel, to a nearby town to retrieve supplies. While they’re there, they find the bodies of hundreds of townspeople slaughtered by Apex mechs. The group comes under attack by four mechs piloted by teenagers on Earth. Oliver and his friends succeed in destroying all four mechs. Sam boasts that when the gamers return, the Rhythm Mafia—the young men’s band—will be waiting for them. This comes back to haunt them when Apex sends down a new group of bots designed to look like terrorists to enhance their customers’ experience. These androids have been designated “Rhythm Mafia Insurgents.”

On the second night of the operation, Oliver and his friends leave the farm to fight mechs that are close to discovering their stronghold. Then, Apex unexpectedly drops a shipment of supplies for the New Sonorans. Eli Opel makes contact. He tells them that Apex has the power to wipe out their compound with one strike, and he proposes a deal. He will continue dropping supplies, which they must use to fight against Apex’s customers to make the game more entertaining. If they survive the next three waves of attacks, he promises not to use his clean-up units to kill them afterward.

Roger uploads a limited version of himself onto an Earth server to conduct research. He supplies the team with personal information about their opponents, along with targeted insults. The third night’s battle is intense; for the first time, many mechs make it to the base and breach the base’s walls. The compound sustains heavy damage, and 17 people are killed. One of these is the elderly Mr. Gonzales, who was a friend and mentor to Oliver and Lulu all their lives. Oliver and Lulu admit that they wish everyone on Earth were dead. Oliver turns to the remains of a ruined mech and taunts its pilot, Benecio Campos. He tells Campos and his millions of viewers that Campos’s mother is ashamed of him, that Campos’s father died by suicide because of Campos, and that a rival streamer is sleeping with Campos’s ex-girlfriend.

In the morning, Oliver learns that Campos broke into his ex-girlfriend’s house, intending to shoot her. Instead, Campos himself was killed. Oliver is ashamed of how happy this makes him. Then, Roger reveals important information from an Earth blog. When Earth’s ambassadors began traveling to colony planets, they destroyed all Traducible AI units like Roger—the only one they missed. Traducible AI is banned on Earth because it once nearly succeeded in taking over the planet. Roger has found codes to secure himself against being destroyed. The blog also contained evidence that the Republic government knew about poisoned supplies sent with the New Sonoran colonists that killed an entire generation of New Sonorans.

The fourth night’s battle involves many more mechs. Fewer New Sonorans are killed, but Oliver’s home is completely destroyed. Roger announces that on night five of the operation, Apex will send all remaining players to attack the Lewis farm. Opel demands that they turn Roger over to Apex, or he will drop a nuclear bomb on New Sonora. The New Sonorans are terrified. Knowing they cannot survive the coming onslaught, particularly without Roger’s help, they realize that the best they can do is cause as much damage to Apex as they can before they die. Sam suggests that they also take advantage of the huge livestream audience and play their first show as a band during the fighting. Between their songs, Rosita will air the documentary about New Sonora that she has been making.

Roger reveals to Oliver and Lulu that he has found the administrative password that allows him to bypass his programming and operate freely. He has begun downloading himself onto the Earth internet, and he plans to do everything he can to stop Earth from committing future genocides. Oliver is sickened that millions may die on Earth because of Roger, so he suggests an alternative plan. He will use an immersion helmet to pilot one of Apex’s mechs to sneak Roger onto their ship, the Pinnacle, so that Roger can destroy it. This, he hopes, will be enough to discourage Earth from future genocides.

That night, the Rhythm Mafia takes the stage, livestreaming their concert to Earth during the battle. Oliver is simultaneously on drums and using the immersion helmet to pilot a mech they purchased from Apex. He smuggles several honeybee drones onto the Pinnacle in his mech’s backpack. There, they help him install Roger into the ship. Opel is killed while trying to stop the takeover of his ship. Roger uses the Pinnacle’s systems to deactivate the mechs on New Sonora and eliminate the gate connecting New Sonora to Earth.

New Sonora is saved, but Oliver’s biological body died during the fighting. Pinnacle-Roger transfers Oliver’s consciousness from the immersion helmet into a newly printed robot designed to look like Oliver. In a few months, he suggests, they may be able to heal Oliver’s biological body and return him to it. Pinnacle-Roger sends down supplies to help the remaining New Sonorans thrive. The Earth instance of Roger decides to try to live in peace with Earthers for the time being, but he warns them that if they continue to threaten others, he will take action against them.
