YouTube said that a North Korean propaganda video showing New York under attack had been removed from the site following a copyright complaint by the makers of the Call of Duty video game.
The video was "taken down by the user" after the complaint was filed by US-based Activision, the publisher behind the blockbuster military shooter video game franchise.
The video uploaded on Saturday by North Korea's official website, Uriminzokkiri, was available long enough to catch the eyes of gamers, some of whom returned fire via YouTube after noting the similarity of its animated sequences to those in Call of Duty.
A response video titled North Korea uses Call of Duty Footage in Propaganda - presenting a side-by-side comparison of the animated scenes - had logged more than 8,000 views by Thursday.
"This is just sad," wrote a gamer in a chat forum beneath the comparison clip at YouTube. "Whoever made this in North Korea is extremely lazy."
Videogame lover Mitchell Kernot of California described it as "weird." Activision did not respond requests for comment. The video posted by North Korea, believed to be on the brink of conducting a nuclear test, was shot as a dream sequence.
It features a young man seeing himself on board a North Korean space shuttle launched into orbit by the same type of rocket Pyongyang successfully tested in December.
As the shuttle circles the globe, to the tune of the US charity hit We Are the World, the video zooms in on countries below, including a re-unified Korea.
The focus then switches to a city - shrouded in the US flag - under apparent missile attack with its skyscrapers, including what appears to be the Empire State Building, either on fire or in ruins.
"Somewhere in the United States, black clouds of smoke are billowing," ran the caption across the screen of the removed video.
The video ends with the young man concluding that his dream will "surely come true".
