Mortal Kombat Trilogy is a compilation of content from the previous Mortal Kombat titles, based primarily upon the gameplay mechanics of Ultimate Mortal Kombat 3. It follows the same story as UMK3, but contains all characters and most of the stages from Mortal Kombat and Mortal Kombat II as well.
If you're eager to see more highly glitched Mortal Kombat action, consider watching the SNES run.
The audio in the encodes of this movie has pops and clicks due to sound emulation problems in mupen64.
