As an Expanded Game from 1995, this fighting title merges content into a definitive package, featuring 23 immediately available characters like Sub-Zero and Scorpion, plus unlockable bosses. You engage in one-on-one combat, two-on-two tag battles, or an 8-fighter tournament across new and interactive stages. The story centers on Shao Khan's quest for revenge and the rebirth of Queen Sindel in Earthrealm. Its value lies in consolidating a vast roster and varied modes onto platforms including Arcade, PC, and SNES.
The narrative plunges players into a realm under threat. Emperor Shao Khan continues his relentless pursuit of vengeance, dispatching his legions to claim the souls of Earthrealm. Central to this conflict is the reported rebirth of Queen Sindel within Earthrealm, awaiting her dark sovereign to facilitate the ultimate unification and domination of both dimensions.
As an expanded iteration, this game emphasizes content availability from the outset. Players gain immediate access to a roster featuring 23 distinct fighters, including established favorites such as Scorpion, Sub-Zero, Sonya, Jax, and Kitana, alongside others like Reptile and Cyrax.
Beyond the standard one-on-one duels, the game offers varied competitive modes. Players can engage in two-on-two tag team battles or participate in an extensive 8-fighter tournament structure.
The value proposition of this version lies in its consolidation of content. It integrates elements from previous iterations, presenting a definitive collection of fighters and stages available immediately upon starting. Furthermore, the game introduces new environments, some of which feature interactive elements that influence combat flow. The roster is supplemented by two unlockable boss characters, adding depth to the available selection beyond the initial 23 combatants.
This release is presented as a complete package. There are no recorded official DLCs, expansions, or remasters associated with this specific version, meaning the content available at its 1995 release represents the final scope of the title.
This fighting title has seen wide distribution across multiple generations of hardware, ensuring accessibility across various systems. Key platforms include the original Arcade hardware, PC (Microsoft Windows), Sega Saturn, Super Nintendo Entertainment System, Sega Mega Drive/Genesis, iOS devices, and the Xbox 360.

Ultimate Mortal Kombat 3 Wave Net (an abbreviation for Williams Action Video Entertainment Network) was a planned network version of the game that allowed for online multiplayer matches. Notably, it is the only arcade version to feature Noob Saibot as a playable character. It was tested only in the Chicago and San Francisco areas that used a dedicated T1 line, connected directly to Midway's Chicago headquarters. It is highly unlikely that any Wave Net test games were ever released to the public after the infrastructure was dismantled, and so there are no known ROM image dumps of this version. One of the reasons this version was not widely adopted was the cost of T1 lines at the time: the setup cost several thousand dollars per arcade installation, plus a few hundred dollars for each cabinet using the hardware. Williams' plan was to use WaveNet to upload new games and game updates, which they would provide to arcade owners for free in exchange for a cut of the games' revenues. The Wave Net version ultimately received its first full release as part of the Mortal Kombat: Legacy Collection compilation in 2025.
