Save files from the end of the game, for the achievements "Full Paragraph" (Bad Ending) and "Well Done" (Good Ending).
You need to upload your saves to the %LOCALAPPDATA%\QZSim\Saved\SaveGames\ folder (there will be a folder of numbers below – just open it; it will contain Save0, Save1, Save2). To avoid overwriting your save, you can use a free one; they are listed in order 0, 1, and 2. Simply rename the desired file to the desired slot.
You can also create a bad ending yourself from your own file by replacing the save file, opening it in UE Save Editor and replacing all EQzEvacuationResultStatus::Success with EQzEvacuationResultStatus::Failed (you must first rename the file with the ".sav" extension, otherwise the online editor will not open the file. Once you change it, save the file without this extension) or download the attached ones (they may become outdated someday and it would be better to make one from your own walkthrough).
