# At the start, fall into the [[damaging floor|lava]] at the right hand side, then go to the [[teleporter]] in the south. Instead of entering it, press on the wall behind it. There are some [[health bonus|health]] and [[armor bonus]]es here, as well as a switch for a lift that will take you to a [[megaarmor]]. ('''sector 45''')# At the rectangular hub, take the left path. After the bend, press on the south wall to find [[stimpack]]s and a [[box of ammo]]. Look out for the [[imp]] that appears as you get them. ('''sector 99''')# After getting the yellow key, find the satyr switch will yellow bars around it and use it. Another switch is behind that switch. Use that one and leave the yellow key area. At the U-bend in the hallway, the inner bend will be open, revealing a corridor to a teleporter. When you take it, press along the north wall to find a [[backpack]]. ('''sector 227''')# Leave Secret #3 (or from the rectangular hub, take the right path) and go to the balcony of the next area. Take the north door, and in the next room, turn right and use the wall to the left of the box of ammo. The passageway has armor bonuses and a [[box of rockets]] and eventually leads you to the supplies on the desks in the room. ('''sector 254''')# Leave that room and go down the lift to the lava area with multiple platforms. Cross them (or just simply go to the cave to the south) and head all the way south. Take the lift up and use the skull switch to raise a block going west. At the dead-end cave, use the wall next to the box of ammo for a switch, which reveals a passage to the left, back to the starting area. In this area, go south on the walkway and press on the red wall at the end to get a [[soul sphere]]. ('''sector 296''')# In the arena where the [[rocket launcher]] is, go towards the west set of steps and use the south wall. A [[spectre]] guards a teleporter here. ('''sector 425''')# The teleporter in the previous secret takes you to a ledge southwest of the arena with some [[ammo clip]]s. To get the next secret, turn to the east and press on the furthest light fixture on the wall. There will be health and armor bonuses, a [[medikit]], boxes of ammo, and a switch here to open the windows at the entrance to the arena. ('''sector 448''')
