This morning, id Software dropped ports of Doom (1993), Doom 2, and Doom 3 on PS4 as well as other current generation systems. This is to coincide with Quakecon happening this weekend in Grapevine, Texas. You will need to register and login to a Bethesda Account to play Doom and Doom 2 offline. Here’s a link to the tweet below:
UPDATE: Clarified which ports need a Bethesda.net login.
UPDATE 2: Bethesda clarified the reason for Bethesda.net login will have it optional in an update soon
