The film's director Simon McQuoid met with Wallfisch early on in pre-production even before his involvement confirmed in March 2021,[4] which he described it as an "instant connection", adding that "the music in Mortal Kombat is such a big part of it" on using the pre-existing themes from the video game series.

Hence he tried using different tones and experimented with the music, to replicate the energy and intensity of the "avant-garde" action sequences and distinguish it with the characters and story, that led to Wallfisch calling it as "the most challenging things he had ever done".

"[10] Empire-reviewer Amon Warmann called it as a "clever, energetic score" that gives us "one of the best musical moments of the year in waiting for the perfect time to unleash the iconic opening notes of ‘Techno Syndrome’ speaks volumes to the respect Mortal Kombat 2021 has for its audience.

The album is a challenging prospect for any audience due to the score's split personality, but there is intelligence in this music that goes far beyond the pointless muck that most composers would have thrown at this concept's filmmakers.
