RAGE SECRET DOOM LEVEL

This Easter Egg is located in the Gearhead Vault, within Subway Town. You can access it through a main story quest. Once you re able to access this area, clear out all the enemies and head towards the area near the end with the computers. You ll need to activate 7 of them as shown in the video, and you ll hear a distinct sound effect from DOOM for every keyboard you interact with. Once you ve activated them all, head back to the beginning entrance, and a previously locked door will now be accessible. You will then find a teleporter that will transport you to a classic DOOM level. In that level, you will find a DOOM Marine Bobblehead.
