How to try itHow to install and play WaW Halo 3 Zombies (Halo 3 in World at War's Nacht der Untoten) · about 45 minutes
WaW Halo turns Call of Duty: World at War’s first zombies map, Nacht der Untoten, into Halo 3. You play Master Chief, the zombies are Flood combat forms, and the guns, grenades, sounds and HUD come from Halo 3. You can dual wield, and a Pack-a-Punch machine turns each gun into its Halo: Reach, ODST or Halo 2 version. Version 1.1.0 (9 October 2026) added an Active Camouflage power-up dropped by the Flood, Halo 3’s grenade fuse times and rates of fire.
Unlike most entries here it’s a classic map mod built with World at War’s own mod tools, not a passthrough or rewrite. The package holds no game files: Install.bat reads your copies of World at War and Halo: The Master Chief Collection and converts the models, textures, sounds and animations on your PC. It’s Windows only. The README credits Claude Opus 5.5, which co-authors most of its commits.
