Originally conceived as Operation: Sturmabteilung with a slated release in Spring 2005 and announced on the Dome news on November 16, 2004, the mod was made in the spirit of John Bucksnort, using DOOM sprites, Spear of Destiny wall patches, but still delving in to The Final Solution and Kristallnacht much as Abandon had. Graphic resources were also found on the Image World.
The Read Me file contains a level guide that alludes to the fact that Thomas still envisioned his mods as having a seamless level flow although they did not.
The name of the mod has no meaning and roughly translates as "eight love".
Thomas had many projects going at the same time and had many ideas he wished to pursue. Operation: Achtliebe was one of many which, after a brisk progress, was put on the back burner as another idea took the spotlight: Project Wolfgeist.
As with Abandon, this mod plays with an episodic flow. Four full episodes were finished, and though Episode 5 is made unavailable as it has no starting point, it can easily be played if fixed in a map editor. The first two levels were finished for that particular episode before being tied up and sent to Brian Lowe via e-mail and released as a demo on December 20, 2004. As he had done with Abandon, Brian made a custom EXE that fixed changed ceiling colors and added 110 % health and 200 ammo.
Together with Abandon, this mod was released in the same month that brought the community Spear: End of Destiny, and as such, interest was limited. Though it is a slight step up the ladder from Abandon, Thomas' map making still had a long way to go.
It was ported to SDL and released on June 18, 2013.
