Live action is a video game series originally developed by the Chicago studio of Midway games in 1992. With midway's bankruptcy, the real fight development team was acquired by Warner Bros. and became netherrealm studios. Warner Bros. interactive entertainment currently owns the copyright of the series and was restarted in 2011. The development of the first game was initially based on the idea of ED boon and John Tobias to produce a video game starring Jean Claude Van Damme, but when this idea failed, a fight game with the theme of fantasy terror was produced, named "real quick fight". The original game produced many sequels and established a media franchise, including several action adventure games, movies (with animation and live scenes of their own sequels) and TV series (animation and live scenes). Other derivatives include comic books, card games and reality shows. Along with Capcom's Street Fighter and Bandai Namco Entertainment's Tekken, live action has become one of the most successful combat Series in the history of video games. By June 2000, the franchise had generated $5 billion in revenue, making it one of the highest paid media franchises ever.

The series is known for its high level of bloodshed, the most famous of which is its death (to complete an action, a series of keystrokes are required to execute it). To some extent, the fatal accident led to the creation of ESRB video game rating system. The series name itself is also known for using the letter "K" instead of "C" in the hard C sound, so in later games, the word "combat" was intentionally misspelled and misspelled in the hard C sound. Series. The early games in the series are also known for their lifelike digital sprites, which distinguish them from their contemporary hand-painted counterparts, and the widespread use of palette swapping to create new characters.

The first three games and their updates, live action (1992), live action II (1993), live action 3 (1995), final live action 3 (1995) and live action Trilogy (1996), were designed in two-dimensional combat. Fashion. The first two of them are played in the game hall with the joystick and five buttons: high fist, low fist, high foot, low foot and blocking. A sixth "run" button has been added to live call 3 and its updates. The characters in the early real-life fast play games were almost the same as each other, and the only major difference was their special actions. Throughout the 1990s, developers and publisher midway games used four attack buttons to keep their single style fighting action in different ways of boxing, kicking and blocking. Real quick hit: the lethal alliance has changed this by differentiating the normal actions of characters and even giving them multiple ways to fight. From deadly alliance to real fight: deception, each character will have three fighting styles: two unarmed styles and one weapon style. There are almost no exceptions in "real quick fight": there is only one style of fighting, such as the role of boss like Moloch and Onaga. While most of the styles used in this series are based on real martial arts, some are completely fictional. For example, five Lang's fighting style is designed to take advantage of the fact that he has four arms. For the end of the world war, due to the large number of characters available, each character can only reduce at most two fighting styles (usually a close combat style and a weapon style). Real fight and DC Universe gives up the trend of multiple fighting styles completely, but provides more kinds of special actions for each character, but some characters still use multiple fighting styles. In 2011, Mortal Kombat returned to a 2D fighter, although the character was rendered in 3D. Unlike the previous MK games, each of the four attack buttons of the controller corresponds to one of the character's limbs, so these buttons become forward, backward, forward and backward kicks (forward and backward means that the limbs are closer to the opponent, respectively).
