# GearsUE3: rebuilding Gears of War around Xenia dynarecs

> GearsUE3 is developing a native engine port for the Xbox 360 Gears of War games, with Gears of War 1 as its active target. Its planned product combines Xenia Xenon dynarecs and system services with title-specific native function overrides. The repository records code maps and reverse-engineering findings. The current launcher cannot start that product because image loading and runtime composition remain unwired.
