A playable Fortnite-style battle royale prototype with building, shooting, bots and a shrinking storm was built by Claude Sonnet 5.5 from a single detailed prompt in about 2h54m, as a test of the model's one-shot capability.

Full prompt445 chars

Create a playable Fortnite-style battle royale with a third-person camera, smooth movement, aiming, shooting and reloading. Add enemy bots, weapon pickups, health and shields, an inventory and a minimap. Include building with walls and ramps, plus a shrinking storm that forces players closer together. Create a colorful island with grassy hills, trees and small towns. Make the lighting, animations and UI feel as close to Fortnite as possible.
