Upgrading Into the Breach (GOG - for Linux)

I bought Into the Breach on Galaxy of Gaming for linux on release. In July 2022, Subset games released Into the Breach Advanced Edition, [(1)][1] a free expansion of the original. This article details how I upgraded and moved my save game files across to the latest version of the game.

Game save data is stored in files with the names in the foramt: profile_{Name}. [(2)][2]

The first version I installed was GOG v1.0.10 (2-28-2018). This version was run via wine [(3)][3], and installed to ~/.wine/dosdevices/c:/GOG Games/Into the Breach/. The save game files (eg. profile_Alpha) were saved in the top level of this directory.

I installed the latest version of Into the Breach from GOG as of Feb 2023: v. 1.2.86 (10-10-2022). The installer prompted for an install location, with a default of ~/GOG Games/Into the Breach. I chose the default location and let the intaller create a desktop file etc. On install, it was clearly quite different to the old version
