Battle City was released by Namco for the Famicom in 1985 and later for the NES, building on the arcade game Tank Battalion. Players control a small tank, clearing enemies while protecting their eagle base, a simple setup that became a staple on multicarts and handheld clones. In many countries it was simply known as the childhood tank game, or Tanki, and its opening music stayed memorable because it played at the start of every stage. Emulators, retro videos and meme edits have kept the jingle circulating decades later.
