UPDATE (15/05/25, 9:00 AM BST): The 'Slayer of Kvatch' mod has been taken down from Nexus Mods, with its page now noting that: "The mod you were looking for was removed by a member of staff." The mod's creator has reached out to VG247, claiming that this takedown was due to a request from Bethesda. VG247 has reached out to Bethesda for comment.
UPDATE: Rip and Tamriel: Doom's Praetor armour has been modded into Oblivion Remastered, so you can practice for The Dark Ages by duffing up Daedra
