What is verified
The official beta description explicitly lists cleansing Beacons among its activities, and Steam displays a Cleanse all Beacons achievement.
Route status
We are not publishing guessed coordinates or an incomplete map. The full all-Beacons route will be added after locations are verified in the release build.
Related progress
The beta also includes optional dungeons, hidden mini-bosses, Marrow Keep, and progression toward Magdalena.
