Essentials
You will start in the southern part of a caged central interior. The other parts have a red skull key, a blue skull key, and a BFG 9000. From the start head straight south to the switch here to open the door leading to the underground cavern. The cavern is vast with a number of enemies dotted around it, so be careful of where you are at. In the northeast part of the cavern is a small room. Hit the eye switch to open the doors around here and grab the megaarmor if you need it. You will find blue doors to the north; they lead to the exit. Go to the western part of the cavern and you will find an opening inwards. Go here and hit the switch to open the door you see through the window. Get out of there, and head around the red rocks till you reach this door. When you enter, you may here a door open. Go back to the opening to find a secret if you wish. Otherwise, follow the linear path and you will eventually acquire the red skull key from the center. When you do, notice that the place around you shapeshifts, and you are able to head back to the beginning through a new tunnel. Do so, and head back into the cavern. Now find the red door, it should be in the southeast part of the cavern. You can find a second red door as well. One just leads you to an ammo depot, so should you need supplies, get them here. Otherwise, take the door leading into the sanctum again. Head left, up the stairs to a switch, and then after pressing it take the other route and you should find the blue skull key. Again, the sanctum will shapeshift, and a baron of hell will teleport in. You may find an extra switch here, which lowers the central teleporter. Take it from various sides to find various things. Otherwise, with the blue key handy it is time to head to the northern part of the cavern where the exit is. Behind the door, the exit is just to the north.
