Doom Eternal has many collectibles that can be found and collected by gamers. Unlike DOOM 2016, in which you could enter cheat codes through the console line, for codes in Eternal you will need to find flexible media (floppy disks) hidden at different levels. In total, you can find 14 cheat codes, and we described their location below.
To simplify the search for cheat codes, we give their location in chapters, as we move along the plot of the game. Below you will find out what a particular cheat code does, as well as where it can be found at the story level. The chronological order will allow you to collect all the cheats already in the first passage of each task.
Cheat code “Endless Lives” – Quest “Hell on Earth”
You can unlock this cheat code during the first story quest. Continue to pass the level until you get out of the subway, wherein in the end, there will be a Code page. Follow further until you reach a room with three zombies, a soldier, and an explosive barrel. Kill the enemies and go forward. Tentacles will appear for the first time. On the right side, you will find a box that you can climb. Do it and climb even higher into the ventilation. Get through it and find yourself in an area with a secret.
What gives: endless extra lives, allowing the Executioner to be reborn right during the battle.
Cheat code “All runes” – Base Stronghold of the Guardians
Sentinel Stronghold has a total of two cheat codes. However, at the beginning of the game, you can access only one. After you get the two batteries of the Sentinels (and unlock the Stronghold control panel), go to the back of the ship, go down and turn right to the door behind which there is an outer tower. When you open it with two batteries, then unlock the Praetorian armor (skin for the Executioner). Having done this, inspect the room and on the left, you will find a hole in the wall. Jump through a hole into outer space, turn around and jerkily get to the secret room below. When you pick up the cheat code, a portal will appear here, allowing you to go back.

Immediately turn towards this tower and jerk to its top. There you will find a cheat code.
