Note for Quest Users
It looks like earlier versions of the Quest APK didn’t require file verification, but the latest version does check for the presence of the original Amnesia: The Dark Descent files. If required, please consider purchasing a legitimate copy of the game to support the developers.
That said, the full game installation takes up around 2.36 GB of valuable internal storage on the headset.
If you're just looking to test Sclerosis VR or want to avoid filling up your Quest's storage, you can use this dummy file pack instead. It replicates the full folder and file structure from the Steam version, but with 0-byte placeholder files; enough to pass the app’s verification check.
Just extract the archive and place the "Amnesia The Dark Descent" folder into the root of your Quest's internal storage.
This works as of Sclerosis_QuestVR_v1.9.12.

I also recommend Quest Games Tuner to enhance the visuals of the game.
