Castle Grayscale

Castle Grayscale is the fourth Doom Eternal event, though as a "Mini-Event", its contents are not assigned a series number. The original series run extended from June 25 to July 2, 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. So far it has not been converted by Bethesda into a premium pack, but its contents have also not yet re-appeared in the rotation since their initial run. As a mini-event, this series only contains six items versus the usual fifteen or more.
