DCII Mash-up (Infinity Mix) is a music track that is unlocked during the 2011 Hallowe'en event and at any Hallowe'en event thereafter. The "Infinity Mix" in the title refers to the stage name of Minstrel Web, who plays the track during the Deathcon II party.
- It is the first EDM song in RuneScape.
- Originally, players who missed out on this song due to not doing the event were "locked out" of getting a Completionist cape since this was the first event where the song was not unlocked automatically afterwards. It has since been added to the list of "automatically unlocked" music tracks.
