Cheat codes for DOOM Eternal that open weapons and armor, give endless health and ammo, costume improvements, skills, etc. However, you can’t just enter the code: they are presented as cards scattered all over the game, and you need to find them first.
Once you find the cheat code, you can activate it on the mission selection screen in the Fortress of Destiny. It is worth mentioning that you can activate cheats only in an already completed mission – you can’t use the cheats for new tasks.
