Beginning in Deadly Alliance and until Mortal Kombat: Deception, the characters would have three fighting styles per character: two unarmed styles, and one weapon style. Mortal Kombat: Deadly Alliance changed this by differentiating characters normal moves and even giving them multiple fighting styles. Through the 1990s, the developer and publisher Midway Games would keep their single styled fighting moves with four attack buttons for a different array of punches and kicks and blocks. Characters in the early Mortal Kombat games play virtually identically to one another, with the only major differences being their special moves. Mortal Kombat 3 and its updates added a sixth "run" button. The first two of them were played in the arcades with a joystick and five buttons: high punch, low punch, high kick, low kick, and block. The original three games and their updates, Mortal Kombat (1992), Mortal Kombat II (1993), Mortal Kombat 3 (1995), Ultimate Mortal Kombat 3 (1995), and Mortal Kombat Trilogy (1996), were styled in a 2D fighting fashion. Early games in this series were also noted for their realistic digitized sprites (which differentiated it from its contemporaries' hand-drawn sprites) and an extensive use of palette swapping to create new characters. The series name itself is also known for using the letter "K" in place of "C" for the hard C sound, thus intentionally misspelling the word "combat", as well as other words with the hard C sound within later games in the series. The Fatalities, in part, led to the creation of the ESRB video game rating system. The series has a reputation for high levels of bloody violence, including, most notably, its Fatalities (finishing moves, requiring a sequence of button inputs to perform). As of June 2000, the franchise had generated $5 billion in revenue, making it one of the highest-grossing media franchise of all time. Along with Capcom's Street Fighter and Bandai Namco Entertainment's Tekken, Mortal Kombat has become one of the most successful fighting franchises in the history of video games. Other spin-offs include comic book series, a card game, and a live-action tour. The original game has spawned many sequels and has spun a media franchise consisting of several action-adventure games, films (animated and live-action with its own sequel), and television series (animated and live-action).

The development of the first game was originally based on an idea that Ed Boon and John Tobias had of making a video game starring Jean-Claude Van Damme, but as that idea fell through, a fantasy-horror themed fighting game titled Mortal Kombat was created instead.

Interactive Entertainment currently owns the rights to the franchise and rebooted it in 2011. Following Midway's bankruptcy, the Mortal Kombat development team was acquired by Warner Bros. Mortal Kombat is a video game franchise originally developed by Midway Games' Chicago studio in 1992.
