One sentence. No design document. The machine invented saints, sinners, a bowling combo system, a police force and a fan club that runs into traffic for selfies, and we were too scared to ask why.

THE ENTIRE GAME DESIGN DOCUMENT

THE PROMPT THAT STARTED IT ALL 🧠

> Create a fun 3D car arcade game cross between carmageddon and crazy taxi called "Karmageddon".▌

That’s it. That’s the brief. Everything else — every line of code, every pixel, every note — came out of the machine. Typos preserved for authenticity.Disclosure: a human may have intervened afterwards, when the machine made the first upgrade cost more than the GDP of Wales, or decided a run should last eleven hours. Even then, the human only fixed it by typing more prompts and sighing loudly. 🫠

About the Slop

Karmageddon is a 3D arcade taxi game in a sunny low-poly seaside city: Crazy Taxi’s race against the clock, with Carmageddon’s pedestrians, rival cabbies and smashable everything. You drive a spiked yellow cab, pick up fares at the kerb and follow the big green arrow to their stop before their meter runs out. Every fare buys more time on the clock.

Downtown is a grid of towers. Beyond it, Hill Road winds through the suburbs to the sea, Bayview Road wanders across the south and the coast road curves along the beach to the pier. Four rival cabbies hunt you and steal your waiting fares.

The twist is karma. Saints tip only if nobody gets hurt, sinners tip for every pedestrian you bowl over, and thrill-seekers tip for jumps, drifts and near misses. Bad karma sets the police on you; good karma sends your fans running into the road for a selfie. Push the meter to either end for KARMAGEDDON: Heaven Sent stops the clock and doubles your fares, Hell on Wheels sets the taxi on fire. The moral framework was also generated. It shows.

How To Play

A quick guide for your first session. The machine wrote the game; we wrote this bit from its README.

  1. You start with 75 seconds on the clock. The game ends when it runs out.

  2. Stop beside a waiting fare in a coloured ring to pick them up: gold for saints, red for sinners, cyan for thrill-seekers.

  3. Follow the green arrow to the green beam of light at their destination and stop in it to drop them off. Faster drop-offs earn more time.

  4. Drive to suit the passenger: clean for saints, carnage for sinners, jumps, drifts and near misses for thrill-seekers.

  5. Ram the rival cabbies nose first to wreck them for cash and ten more seconds, and grab blue clocks, green spanners and orange nitro on the road.

  6. Watch your karma: bad karma brings the police, who bust you if you sit still, and good karma brings fans into the road. Push it to either end for twelve seconds of Karmageddon.

Changelog

Every update below was also made by the machine. We just pressed Enter again.

    • The city has grown: downtown keeps its grid, but now winding roads run through the suburbs and a coast road follows the beach to the pier.
    • The death racers have been replaced by four rival cabbies, who hunt you down and steal your waiting fares. Rude.
    • Bad karma now sets the police on you, up to three cars. Sit still next to one and you get busted: eight seconds off the clock and your fare gone.
    • Good karma brings your fans running into the road for a selfie. They do not move. Running one over is, karmically, a lot.
    • Bigger pick-up and drop-off zones, and the minimap traces your route and zooms out as you speed up.
