TRIVIA: Sound engineer Allister Brimble explains the musician credits:
"I was contracted by Probe software to do the Mortal Kombat 2 audio. The original Arcade music was by Dan Forden and needed squashing down into 3 channels for the Amiga. My time was required to work on the SFX and another project, so the music arrangement work fell to Anthony Putson who I had received some demo's from and was very proficient at .MOD creation. After receiving the .MOD files back, I optimised the instrument samples by hand to get them a little smaller and plugged them into my sound driver."
