Oopsie: Publisher Bethesda apparently made a big boo-boo with its recent launch of Doom Eternal. As users on Reddit and ResetEra quickly discovered, the publisher “accidentally” left a DRM-free copy of the game’s executable in the download package.

It was confirmed earlier this week once the review embargo lifted that Doom Eternal would use anti-tamper technology Denuvo to help slow piracy out of the gate. Once users had a chance to poke around the game files, however, they discovered a DRM-free executable sitting right there in plain sight – in a folder labeled “original,” nonetheless.

According to this Reddit user , the primary executable weighed in at 369 MB and could be found in the main game folder. In the subfolder, there was a smaller 67 MB executable that could easily be copied to the main folder to overwrite the Denuvo executable.

From there, all you had to do was launch the game, create a Bethesda account (this appears to be a mandatory step although according to Ars Technica , crackers have already discovered a workaround to enable a fully offline experience) and start playing.

As you’ve likely guessed, Bethesda was quick to issue a patch that removed the DRM-free executable but the damage has already been done and the publisher has nobody to blame but itself for seeding a DRM-free version of Doom Eternal.

This isn’t the first time such a thing has happened, either. Bethesda experienced a similar slip up last year with Rage 2 and ultimately removed Denuvo from the Steam version days later.
