in the credits says "MK4 coming in 1997". The PlayStation version of the game exhibits a number of bugs when played on a PlayStation 2 or PlayStation 3 console which causes the to game freeze at certain points. Nintendo 64 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. For some MK3/UMK3 backgrounds, the incorrect background track is used compared to one used for arcade UMK3. Due to cartridge limitations, only 30 characters are included, instead of the 37 featured in the other console versions. The N64 port lacks Goro and Kintaro; the classic versions of Jax, Kung Lao, Kano, and Raiden; as well as the unmasked Sub-Zero (however, the masked Sub-Zero can perform both Sub-Zeros' special moves). Chameleon is replaced with the secret character Khameleon, a grey female ninja that randomly switches between Kitana, Mileena and Jade. The N64 version of the game, like MK3 and UMK3, provides the player with an "Ultimate Kombat Kode" screen after a single-player game is over, where a 6-digit code can be entered to unlock Human Smoke and Khameleon for normal play. Like the Saturn version, the font of the lifebars for the male and female ninjas is of a different font (Revue) versus the other characters (italicized Arial). Further, the "new" characters: Noob Saibot, Rain, Baraka, Rayden, Johnny Cage, and Khameleon use italicized Arial, but with greater spacing than the original MK3 characters. Also, the announcer does
