Mortal Kombat Mythologies: Sub-Zero is a 1997 action-adventure beat 'em up video game developed and published by Midway for the PlayStation and Nintendo 64. A spin-off/prequel of the Mortal Kombat franchise, it is the first installment to not be a fighting game. Set before the first game Mortal Kombat, players control Bi-Han, the elder Sub-Zero, during his quest to find Shinnok's amulet. It also serves as a prequel to Mortal Kombat 4, which was released the same year, introducing characters and story elements that would be used by the fourth main installment. Mythologies is the final game in the series to use digitized actors. The game drew a divisive response from critics, with the PlayStation version considered superior to the Nintendo 64 version. Praise was directed at the transition from the fighting game genre to action-adventure and the PlayStation version's live-action cutscenes, but the controls and punishing level design received criticism. Retrospective reviews were more negative, with some considering the game as one of the worst in the Mortal Kombat franchise.

The player has four attack buttons, along with a block button and a run button like in Mortal Kombat 3. The player controls Sub-Zero as they would in a fighting game, including the use of command-based special moves, to fight enemies and venture through levels. A "turn" button is used to change the direction Sub-Zero is facing, while an "action" button is used to pick up or use items. The player also has access to a status screen that keeps track of the players inventory, experience points, and special moves they gain during the game. The player begins the game with a small health gauge and a limited number of extra lives. Over the course of the game's progression the player can gain experience points by performing combos against enemies, which are then used to increase their characters strength and gain access to special moves. An "ice meter" will appear after the player begins to acquire special moves. Special moves require ice power in order to be performed. Health and ice power can be replenished by picking up items (although the ice meter will gradually replenish itself over time as well). The player also needs to retrieve key items. Passwords are used to keep
