Ghost Runner (2020)
EGS DRM test.
Test date: 10/27 - Version: 30658 (Release)
Tested: 'Epic Launcher' Closed/Signed out/Renamed. (All Passed)
Result: The game is DRM-free after installation.
But it seems to have epic integration built-in.
When you start the game, you may be prompted to link an epic account, (Browser pop-up)
This will link your Game Profile (save folder) to your epic account, But can be dismissed without affecting the game.
Yes, the game will run, even if the epic launcher signed-out/closed, even if you link your save file.
However Linking your save will enable Epic features like achievements, and the built-in epic overlay.
(Yes, Epic 'features' work even without
the Epic launcher running)
If you change your mind, you can unlink
your epic account
this may delete your achievements!)
You can do this online, from This Page
Find 'GhostRunner' and click "Revoke access".
This will switch your profile to 'unlinked'. (Your save file will be fine)
Not-linking/unlnking disables the overlay and all epic features.
This means, you will no longer show up as "in-game", and you won't earn achievements.
