About Insert Soul
A short first-person arcade shooter for Windows, made for Halloween and about 15 minutes long. On Halloween night in 1987 you slip into the abandoned Starlite Skate & Arcade; the doors chain themselves shut and a voice on the giant scoreboard, the Operator, says three kids who never went home are trapped inside his machines. Inserting a soul into a cabinet does not start the game on the screen: it bursts out of the glass into the room. In Grave Invaders a marching swarm of bats, skulls and pumpkin ghosts fills the ceiling while you hide behind tombstones; in Candy Crypt neon maze walls rise out of the rink floor as four sheet ghouls hunt you; in Bonepede a centipede of glowing skulls winds toward you; free all three kids and the Operator comes out of the scoreboard for the final round. You shoot with a retro light gun, using keyboard and mouse or a gamepad. The developer, Viktor vs The Future, says the whole game was handed to Claude Code at 1:26 in the morning and was playable by 6:31, after which the developer spent a day polishing it from their own notes and paintovers. Per the developer, Claude Code wrote the code, 3D models (as Blender Python), shaders, game logic and tests, while the artwork came from ChatGPT image generation and the music and the Operator's voice were made by the developer with Suno. Built in Godot 4.7. A free download on itch.io (name your own price) for 64-bit Windows 10 or 11.
How it was built
Partially verifiedThe description of the developer's making-of video (14 Oct 2026) says: “At 1:26 in the morning I handed an entire 3D game to Claude Code: not a piece of code, the whole thing. By 6:31 it was playable.” It describes one lead agent, seven specialist agents and two testers building the game overnight, 39 3D models written as Blender code and 3,654 small details placed by code, a test agent filming the hall at 60 fps to find a flicker bug, and 1,016 automated test games. Its credits read: “Code, 3D models (Blender Python), shaders, game logic, testing and this edit: Claude Code (Anthropic)”, with “Story, direction, notes and paintovers: me”. The video compares what the AI built alone with what it built from the developer's notes and paintovers.

Built in Godot 4.7 by a team of Claude Code agents overnight, then polished for a day from the developer's notes and paintovers. Per the video description, the 3D models were written as Blender Python code, concept art and game artwork came from ChatGPT image generation, the music and the Operator's voice were made by the developer with Suno (lyrics co-written with Claude) and cut into loops and voice lines by the agents, some sound effects came from Stable Audio 3, and free CC0 assets came from Poly Haven (models, textures) and Quaternius (base mesh for the hands). The description names Five Nights at Freddy's and the film Pixels as inspirations only and says no footage from either is used. All of this was made during development; the Windows build itself was not downloaded or inspected.

“At 1:26 in the morning I handed an entire 3D game to Claude Code: not a piece of code, the whole thing. By 6:31 it was playable.”Verification notes: AI use from the description of the developer's YouTube video “AI Built My 3D Horror Game Overnight… Then I Made It Better” (channel Viktor vs The Future, @hallucivids; 14 Oct 2026), read through YouTube's data endpoint on 8 Nov 2026 (the video itself was not watched), and from the itch.io page, re-read the same day. Story, rounds, controls, requirements and file from the itch.io page: published 14 Oct 2026, 17:11 UTC, last updated 20 Oct 2026, 14:32 UTC, status Released, genre Shooter; the page asks players not to re-upload the game or reuse its art, music or code. No share of AI-written code is stated, so none is recorded; the developer's own part is given as story, direction, notes and paintovers. Developer: the itch.io account hallucivids and the YouTube channel use the name Viktor vs The Future; no full name, team size or location is stated, so the record uses the channel name. The same account has also published Spellsnatch and Almost My Room (separate records) and other games. Five Nights at Freddy's and Pixels are named by the developer as inspirations only, with no footage used, so no third-party IP notice is recorded. The game's own text says it was checked with 1,016 bot playthroughs. The video had 7,455 views on 8 Nov 2026 (observed; not a metric). No download count is shown. The Windows build (265 MB) was not downloaded, so it was not checked for AI service calls, and the game was not played.
