"Mortal Kombat 4 is the fifth and final arcade game in the Mortal Kombat series of fighting video games developed by Midway Games. Released in 1997, Mortal Kombat 4 is the first title from the series to use 3D computer graphics as well as one of the first games that Midway made in 3D. Eurocom later ported it to the PlayStation, Nintendo 64, PC, and Game Boy Color during 1998. An updated version titled Mortal Kombat Gold was released a year later exclusively for the Dreamcast.
The gameplay from Mortal Kombat 4 is similar to 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 god Shinnok against his former comrades who trapped him in the Netherealm various of years prior to the series' start: the other 17 playable characters take part in this war, with a group aiding Shinnok and the others attempting to stop him (Mortal Kombat Gold would expand the number of available characters).
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 prequels, removing the comical finishing moves featured in them. Since its release, Mortal Kombat 4 received positive response from critics due to its graphics and gameplay. On the other hand, the Game Boy Color port and Gold received criticism."
