A city built from the real map.

REXA starts from real geography: 126,079 roads and 273,517 buildings from OpenStreetMap, with Copernicus terrain and NOAA ocean-depth data, streamed in one-kilometre chunks. On top of that sits the loop you’d expect — drive, walk, take missions and outrun the police.

The first version was Three.js inside a native Swift iOS app. The second moved to Unity 6 and grew a city-life layer: walking, enterable venues, courier jobs, and cars with working doors and cockpit cameras. The current build runs on Unreal Engine 5, with features developed as separate plugins around a frozen core.

It’s the largest thing I’ve built and it isn’t finished. These are development captures, and the build still leans on marketplace and sample art while the systems come together.

Real-geography city pack

The whole district is compiled from open map data into one binary pack and streamed in 1 km chunks.

Pursuit director

Police units take roles — chase, intercept, flank, block, search and recover — instead of simply following the player.

Deira city life

Walk the streets, enter venues, run courier jobs and earn Rexcoin.

Garage

Ten vehicles with credits and unlocks, and Performance, High and Ultra presets that step down on their own when the frame rate drops.

Built in lanes

The Unreal build is organised as plugins around a frozen core — event bus, world state and saves — so several features can move in parallel.
