Silksong was released. the demand for the game was so high that both the Steam and Xbox Game Pass pages for it crashed.

Our first recommendation would be to use the Xbox mobile app. We've tested this method out here at the PX office, and have managed to successfully get the game installing on Xbox Series X. Simply open up the mobile app, search for Hollow Knight: Silksong, and install it to your device of choice (you'll have to link a device if you haven't already).
