A Call of Duty fan has managed to get the source code for World at War Zombies and has been posting bizarre creations online, including crossovers with NHL and Halo.
On September 6, X user ‘P.E. Cooper’ revealed that he “had opus 5.5 and astra pull the source code for call of duty world at war and port the classic og zombies map over to web.” This allowed them to run the classic mode from their own browser.
Clearly, it also opened the door for them to get creative, as they soon started posting clips of increasingly strange additions to Zombies.
CoD fan uses AI to bring Mario Kart and Madden to OG Zombies
One of the first showed that Cooper had managed to get the Portal Gun from Valve’s Portal 2 in the Mystery Box. But rather than just being a cosmetic, it actually fired working portals that allowed them to quickly navigate the Nacht der Untoten map.
Pretty soon, they were mowing down zombies with a Sith lightsaber, turning their soldier into a crew member from Among Us, and even driving around as Mario from Mario Kart, while tripping up enemies with banana skins.
In a different video, they had introduced Fortnite’s building mechanics into Zombies. They were able to put up wooden walls to prevent the zombies from reaching them.
Things only got weirder, as they posted more clips showing bot teammates that had been transformed into Tung Tung Tung Sahur, Master Chief, SpongeBob SquarePants, and Rick and Morty.
Then, they turned to sports for more crossovers, as another batch of clips showed the playable character being turned into a NFL player from Madden and an ice hockey star from the NHL games. Another featured a Mii from Wii Sports, who slayed enemies with boxing gloves, bowling balls, and a baseball bat.
“When I was younger, I had a meeting with some game studios and they laughed me out of the room… they said my idea was ‘the dumbest fucking thing they’ve ever heard!’ they joked. “Thanks to AI I can finally prove them wrong.”
As it stands, these creations are only available to P.E. Cooper, and not as an easily accessible mod, but if you ever wondered what a CoD collab with Wii Sports would look like, this is probably as close as you’ll get.
