Level 31: Wolfenstein
Back to Doom 2
This level is more for fun than anything else. The map is fairly straightforward and it’s filled with Guards and Demons. The first secret can be found on the eastern side of the map. Hit the wall in the east corner to reveal Secret 1. Inside you’ll find a BFG, Mega Sphere and 4 Backpacks.
Make your way through the rest of the level, taking out the enemies as you go. Once you get to the Exit hit the walls to open up Secret 2, Secret 3 and Secret 4. This will take you to the Super Secret Exit and also give you some extra loot along the way.
