Supergiant reported on Noclip's documentary materials and available footage of the Ballads of the Underworld concert dedicated to the music of Hades.
These materials are suitable for those who are interested in creating a game and its music. Please be aware of possible plot spoilers before watching. The announcement of video and music materials should not be mixed with a game patch: changes to mechanics require a separate update list. Links to episodes and terms of access are in the original message from the studio.
