Essentials
Head around the moat of the fortress until you reach the bridge. Cross it, and you then need to open the front gate of the fortress. To do so, head all the way around to the northern side of the fortress and flip the switch on the wall. Go back around and enter it. You will be trapped in for thirty seconds against some arachnotrons. When the gates open up, go into the main hall, head around the table, and head up the stairs to the right of the door. Grab the yellow skull key on this balcony, then go back downstairs and take the door. Take the steps downward and you will be at a prison block. What you need to do is go to the northwestern block to find the blue skull key. When you do, leave the area, and head back into the main hall. Go up the stairs to the left of the door, then maneuver around the crates until you reach the yellow door. Open it, then open the yellow door to the left. Grab the red key on the balcony, then head back into the main hall. Through the gates outside, a big monster may attack you. It is a spider mastermind on Hey, Not Too Rough or lower, two spider masterminds on Hurt Me Plenty, or a cyberdemon on Ultra Violence or higher. Head up the stairs to the right of the front gate and open the door into a mess hall with imps. Head for the hall to the north and open the blue door. Open the red door to the right, and flip the switch that is next to the blue door on the other side. Now return to the fortress entrance, go outside, and head for the southwest part of the map to find the exit teleporter.

Secrets

 * 1) In the prison where you find the blue skull key, a section of the western wall in the southwest cell block is covered in moss. Open it to find a teleporter leading to the Arachnotron cage in the southwest battlement, where you can get a bulk cell, a box of rockets, and a computer map. (sector 158)
 * 2) In the stairway up to the kitchen, there is a portion of the southern wall covered in grime. Open it to find a teleporter that takes you to the Arachnotron cage in the southeast battlement, where you can get a box of ammo and a box of shells. (sector 368)
 * 3) In the eastern battlement, a section of the west wall is covered with grime. Open it to find a teleporter to the Arachnotron cage in the northeast battlement, where you can get a box of ammo and a box of rockets. (sector 97)
 * 4) In the western storage facility, there is a wall in the northwest corner covered in grime. Open it to find a teleporter leading to the Arachnotron cage in the southwest battlement, where you can obtain a bulk cell and a box of shells. (sector 364)
 * 5) When you grab the red keycard, two southern buildings will open to reveal Spider Masterminds (or a Cyberdemon on Ultra-Violence or higher). Leave the castle and look in the westernmost of these buildings to find that half of the floor and ceiling are covered in moss. Cross the divide between both halves, and then reenter the castle. Backtrack to where you found the yellow skull key to find that a section of wall has opened nearby, allowing you to jump onto the table and acquire sixteen armor bonuses, fourteen health bonuses, and a megasphere. (sector 372)
