"Mechanizing Occupation Project [FILE-13] - Haltmann's Archives" is a lore video and the thirteenth "file" in Haltmann's Archives.
The video is formatted like all Haltmann's Archives videos starting with "[FILE-02]".
The FILE, dated December 22, 2016, is an overview of Grandiose City from the perspective of President Haltmann's forces. The FILE expands on locales shown in The SilvaGunner Christmas Comeback Crisis such as the lighthouse, SiIvaGunner's house, and the Nigra Store. The FILE ends with an update that Angry Joe and Nathaniel Welchert have subdued Santa Claus and allowed the first shipments of Christmas Spirit to come in.
- This video's description contains an Imgur link to the full map of Grandiose City shown in the video.
- "Desolation - Ambient" from Deus Ex serves as the background music for this FILE.
- December 22, 2016 is the five-year anniversary of μ's release of "Snow halation". By this point, The Voice Inside Your Head has ruled Grandiose City for about a week.
- This episode is most likely set during the events of the CCC episode "Advent of Hell", since Santa has just been "subdued".
- The layout of Grandiose City shown in this video is geographically similar to an area in the Dutch city of Rotterdam, leading people to believe they are the same place. This was later confirmed by MtH.
