A full browser port of Nacht der Untoten, the original Call of Duty: World at War zombies map, built by having Claude Opus 5.5 and Astra pull the actual WaW source code and translate it to the web. Running at localhost, it's a faithful first-person survival shooter: dark wooden barricades, fog-choked exterior, zombie silhouettes lurching through the gloom, a classic circular crosshair, round counter, score ticker, and health readout — all intact and playable without any game client.

Opus 5.5 + Astra extracted real WaW source code and ported the full 3D map to a browser runtime
Faithful recreation: round system, score (+110 popups), health bar, and the iconic dark atmosphere all present
Running live at round 21 in the screenshot — this is a fully playable game, not a demo shell
