What is this?
A live test of Claude Opus 5.5's coding ability: three complete 3D browser games, each generated from a single one-sentence prompt in one session, with zero human edits to the code.

The FPS recreates CrossFire's Transport Ship map with recoil, bot opponents and kill announcements, and the racer copies QQ Speed's Shift-drift and Ctrl-nitro handling across four tracks.

The biking game got a 320-second fast-forward soak test with a stable 16-26 MB JS heap, and a separate review subagent found 12 issues that were all fixed before delivery.

The model also did its own research, deployments, and a post-launch fix for a black-screen bug it reproduced by injecting NaN.

The FPS and racer prompts similarly ask for faithful recreations of the CrossFire and QQ Speed maps, uploaded to a CDN with the link sent back.
