Return to Castle Grayscale

Return to Castle Grayscale is the sixth Doom Eternal event, though as a "Mini-Event", its contents are not assigned a series number. It is a follow-up to the first Castle Grayscale mini-event. The original series run extended from August 6 to August 20, 2020. The name of the series is an allusion to Castle Grayskull from the  cartoon series, and refers to the monochrome design of skins contained in the pack. Its contents have also featured as part of the Spring Mega Event spanning from March 3 to May 26, 2022. So far it has not been converted by Bethesda into a premium pack. As a mini-event, this series only contains eight items versus the usual fifteen or more.
