The archive contains a save in the final part of the campaign. Made for those who are stuck at some part of the game and cannot go further along the story due to a bug or a broken script, or for those who just want to walk around the map or take part in the final battle.
Path:
%LOCALAPPDATA%\PhantomDoctrine\Saved\
P.S. If the saves do not work, then you need to start the campaign and save. Then exit and unpack my saves from the folder "76561198117643771" into the folder with your id (that is, your number).
