King of Fighters games are part of a 2D fighting game series developed by SNK. First released in 1994, the franchise became known for its three-on-three team-based combat system, crossover characters from SNK’s other games, and competitive arcade roots. Each installment introduces new fighters and story arcs while retaining core mechanics such as special moves, combos, and player-versus-player matchups. The series has appeared on arcade machines, consoles, and more recently, web-based emulators that allow classic titles to be played in a browser.
