History Line 1914-1918 is a turn-based strategy game released in 1992 for Amiga and PC by German BlueByte GmbH. It was published in the U.S. in 1993 under the variant title Great War: 1914-1918. The game is a spin-off of the better-known Battle Isle series, which moves the action to the First World War. Therefore it is technically based on the first Battle Isle game, released a year earlier.

Compression
All data files of the game are compressed with Turbo Packer by Wolfgang Meyerle (TPWM compression) and must be unpacked before the file contents can be modified. Fortunately, the game checks whether the files are compressed or not and accepts the data files uncompressed as well. Therefore, modified files do not have to be compressed again.
