Knuckle Heads is a two-on-two fighting arcade game that was released by Namco in 1992; it runs on that company's NA-1 hardware, and is the seventh game from them to allow scores that do not end in "0". The US version of this game is also the fifth (and third-from-last) title from the company to display the Federal Bureau of Investigation's "Winners Don't Use Drugs" screen during its attract sequencing.
Up to four players must choose control for six different characters from: the United States, the game's home country of Japan, Greece, China, Norway, and Brazil in what is described as "America's hottest new game show" on the flyer; they all have different special weapons, moves, and catchphrases, and the show will move to each of the characters' respective home towns (Honolulu, Kyoto, Athens, Hong Kong, Lillehammer and Sao Paulo) for each successive round. The gameplay is also reminiscent of a four-player version of Capcom's two Street Fighter games - released in 1987, and 1991, respectively.
