Bethesda, AKQA, and COPILOT Music and Sound collaborated on the marketing campaign for Wolfenstein: The New Order to invent the fictional state-owned German record label Neumond Recording Company. The campaign was crafted to introduce the video game's alternate history in the form of pop music from the 1960s. The label promoted ten fictional German pop artists: seven original songs, and three covers reworked into German from their original versions. Each artist was given a full biography, and the singles were packaged with album cover artwork. The covered songs were featured in trailers but omitted from the game because the songs' owners did not want their work to be associated with Nazi imagery.[a] The original songs created for the Neumond label were initially written in English to ensure that the lyrics reflected Wolfenstein's alternate history without creating content that could be used for actual propaganda outside of the game, given the sensitive nature of the game's subject matter.

I made a FreeDOS-themed 2023 wall calendar for my office, and made it available for anyone to buy. If you want a version for yourself, you can order it on Lulu.
