Save - "Absolute Nightmare" difficulty for a Steam license, no cheats. The archive contains a save with a fully completed game. You can choose any level. Not everything is collected, not all secrets are found, not all tests are completed. But you can finish everything if anyone wants (I will do this later, when I want to return to DUM again). This is only the first version of the save, I plan to post 100% later.

Throw the folder in:
C:\Program Files (x86)\Steam\userdata\1006126451\3017860\remote
