Sean Price was the first artist to contribute a verse to the project. He was set to film a scene later in the year, but had tragically died in his sleep. The final verse was done as a tribute to him and his legacy.
Slaine kills himself in the original "Underworld", and the director thought it would be great if he did it again in sequel, only this time with a different method. Thus creating a sort of "indestructible" element to him in the series. In the first one he drank poison, and in this one he blows himself up.
Havoc's scene was filmed the same day that Reel Wolf filmed his video "Uncut Raw" with Prodigy.
Unlike the first "Underworld", this one features two separate beats, both produced by Sentury Status.
The DJ scratches on the project were done by DJ Illegal of the iconic German hip-hop group Snowgoons, although he does not appear in the video.
