Mortal Kombat 4 (MK4) is the fourth main installment in the Mortal Kombat series of fighting games developed by Midway Games. Released to arcades in 1997, Mortal Kombat 4 is the first title from the series, and one of the first made by Midway overall, to use 3D computer graphics. It is also the last game of the series to have an arcade release. Eurocom (who had previously developed the Sega Saturn version of Ultimate Mortal Kombat 3) later ported it to the PlayStation, Nintendo 64, PC, and Game Boy Color during 1998. An updated version titled Mortal Kombat Gold was released exclusively for the Dreamcast the following year.The gameplay system of Mortal Kombat 4 is similar to that of the previous games; one of the most notable additions is the use of weapons and objects during fights. The storyline chronicles the attack from the corrupted Elder God Shinnok against his former comrades who trapped him in the Netherealm many years prior to the beginning of the series. The other 17 playable characters take part in the battle between good and evil, with the forces of light trying to stop Shinnok and the forces of darkness from conquering all the realms.While developing the game, the Midway staff had problems making the graphics as it was one of the first 3D fighting games they developed. Co-creator Ed Boon commented that the staff wanted to make Mortal Kombat 4 more violent than its predecessors, removing the comical finishing moves featured in them. Since its release, the game received generally positive response from critics, with the exception of the Game Boy Color port.

Mortal Kombat II (commonly abbreviated as MKII) is a competitive fighting game originally produced by Midway for the arcades in 1993. It was later ported to multiple home systems, including the PC, Amiga, Game Boy, Sega Game Gear, Sega Genesis, Sega Saturn, Super Nintendo Entertainment System, and various PlayStation consoles, mostly in licensed versions developed by Probe Entertainment and Sculptured Software and published by Acclaim Entertainment (currently distributed by Warner Bros. Interactive Entertainment).Mortal Kombat II was the second game in the Mortal Kombat series, improving the gameplay and expanding the mythos of the original Mortal Kombat, notably introducing more varied Fatality finishing moves and several iconic characters, such as Kitana, Mileena, Kung Lao, Noob Saibot, and the series' recurring villain, Shao Kahn. The game's plot continues from the first game, featuring the next Mortal Kombat tournament set in the otherdimensional realm of Outworld, with the Outworld and Earthrealm representatives fighting each other on their way to challenge the evil emperor Shao Kahn.The game was an unprecedented commercial success and was acclaimed by most critics, receiving many annual awards and having been featured in various top lists in the years and decades to come. The game caused a major video game controversy due to the series' continuous depiction of graphic violence. It has since been called one of the most controversial and greatest video games of all time. Its legacy includes spawning a spin-offgame Mortal Kombat: Shaolin Monks and having the greatest influence on the 2011 reboot game Mortal Kombat, as well as inspiring numerous video game clones.

Mortal Kombat Trilogy is a fighting video game released by Midway in 1996 as an update to Ultimate Mortal Kombat 3. Unlike the previous title, it was not released in arcades (except for prototypes), but was instead released for the PlayStation, Nintendo 64, Sega Saturn and PCs. Further versions were also released for the Game.com and R-Zone.Mortal Kombat Trilogy features the same gameplay and story as Mortal Kombat 3, but adds characters and stages from the other three arcade games, including Ultimate Mortal Kombat 3. Some completely new characters were also introduced. New additions to the game included the "Aggressor" bar, a meter that fills during the course of the match and temporarily makes a player character faster and stronger. It also features a new finishing move called Brutality, a long combination of attacks that ends with the opponent exploding.The game was met with mixed reviews. The hardest criticism was directed at the Nintendo 64 version, which did not have all the content of the other versions due to limited storage space on the cartridge.
