The Nintendo 64 port is based on the Windows PC and PlayStation versions of "Mortal Kombat 3" and the Sega Saturn version of "Ultimate Mortal Kombat 3". This edition includes 3-on-3 simultaneous battles as an exclusive feature. In this version, like in the arcade, the player begins the game with four credits, but after playing a two-player match, the player earns an extra credit, while in the CD-ROM versions anyone can play for free. Free Play must be unlocked on the N64 version, which also has a more cohesive "Supreme Demonstration" feature (which shows every Fatality, Babality, Friendship, Animality, and Brutality for every character) than the PS or Saturn versions (as the latter versions needed to load the Fatalities and thus cannot show every one in the allotted time). This version only uses music from "MK3" and it is played through the system's internal synth, resulting in considerably lower quality than the CD versions. However, all ending tunes and music loops used during the "Finish Him/Her" sequences are intact, unlike in the CD-ROM versions.
