Two of the in-game magazines reference the livestreaming group Vinesauce, who previously conducted playthroughs of Hypnospace Outlaw on-stream. The first cover, Metal Masters, depicts both Vinesauce members Vinny and Joel, using pictures from their respective bands Red Vox and Scythelord; Joel's bandmate Frank also appears on the magazine cover. The second cover, NerdMaster, depicts Fren, a crude MS Paint self-portrait that Joel created to mimic the art style of QT, a lighthearted parody of PT. Both Vinny and Joel expressed flattery with the former Easter egg when they discovered it on-stream.
