Doom Eternal cheat codes
Unlike previous games, the cheat codes of Doom Eternal are collectible items that must be discovered before they become usable. They appear as floppy disks with designs appropriate to their corresponding cheat.
To activate an unlocked code, choose the Mission Select option from the main menu and pick the desired codes from the "Cheat Codes" menu. Cheat codes can only be used on previously cleared missions and will disable Slayer Gates when active, but any other collectibles found with cheat codes active will still count towards game progression.
Collecting every cheat code will unlock the ability to play the original Doom on the Slayer's computer in the Fortress of Doom. A slight bug noticed with the Berserk Cheat code is that it may play the animation of a chainsaw, but only on Mars Core.
