COD Zombies Portable online game is Nazi Zombies: Portable, a fan-made remake of the round-based Zombies mode from Call of Duty: World at War, rebuilt on modified forks of the 1996 Quake engine and compiled for the browser. It is free and open source. The COD Zombies Portable unblocked game boards you up in Nacht der Untoten and its sister maps, where rounds of zombies come through the windows, kills pay points, and points buy the wall guns, the perk machines and the mystery box that keep you alive one round longer.
What is in this build
The main menu lists Solo, Cooperative, Configuration, Achievements and Credits, with a 2.0.0-indev version stamp and an August 2025 build date in the corner. Solo is the mode that works from a page like this one, because co-op needs a websocket server the client can reach. Rebuild barriers between rounds for points, and keep moving, because this engine has the old Quake speed and the zombies use it too.
The NZ:P Team credits programmers such as Blubswillrule, Jukki and Naievil, and the whole project is on GitHub. For the other jump scares on the site see horror games, and Doom 1 is the other classic-engine shooter here.
