Map of Boiling Blood
Letters in italics refer to marked spots on the map. Sector, thing, and linedef numbers in boldface are secrets which count toward the end-of-level tally.


Press the gargoyle switch in front of you to open the surrounding walls - you will be standing above a triangular blood pit surrounded by zombies, imps and demons, so immediately step forward to land on an armor then collect the shotgun in front of you to protect yourself. Press the lion switch on the south wall to raise the blood up to the surrounding ledge, then head north-east and north along a metal bridge until you reach a stone ledge guarded by a mancubus. Turn left at this point and step south-west over a stepping stone to reach a platform with health bonuses and a rocket launcher, then step south-west again and follow the path past zombies, revenants and demons until you reach a blood river which goes west and south. Head west past a window with more zombies and imps and go through the doorway in front of you, then turn left and walk past a tan marble column to enter an alcove containing the blue skull key.

Retrace your steps to the metal bridge, watching out for an arch-vile that has been released into the blue key area. When you get back to the stone platform that had the mancubus, follow the path east and south to a blue key door and open it to confront a Hell knight (or baron of Hell on Ultra-Violence and Nightmare skill levels). Go through the door and head south-west up some red steps, watching out for spectres and an arch-vile on the way, until you reach a lion switch that will raise the lava around the starting area. After pressing the switch, walk south-west to drop into the lava and find a radiation shielding suit then continue south-west to a door between two blue firesticks that was previously out of reach.

Go through the door to enter a blood-filled hall with zombies and imps but do not spend too long fighting them, as when you enter the room four arachnotrons will appear on the ledges by the east and west walls. Go round to the south-west corner of the room to find a gargoyle switch that will raise the blood, but will also cause an arch-vile (or two imps on I'm Too Young To Die and Hey Not Too Rough) to rise from the floor that you can see through the window. Head through the blood to the south-east corner of the room, where you can now get into the area that the arch-vile/imps appeared from, then flip the switch on the south wall to finish the level.

Other points of interest[edit]

After raising the blood pit at the start of the level, you can reach a chaingun on the north side of the surrounding platform.

When you enter the marble structure before the blue key, head north and east to find a berserk pack. Taking it will open a closet behind you with demons and spectres.

After raising the lava, drop into it and head to the west side to find some steps leading up to a plasma gun - watch out for a revenant waiting in ambush. From the plasma gun, drop down to the platform below to find a lion switch that will raise a lift near the marble structure; you can now walk round to the lift and ride it up, then run south to land on the platform with the cross-shaped blood stream where a super shotgun is guarded by a mancubus.


  1. At the blood river north of the start, get on the east railing and follow it south. When you can drop to the east, do so to pick up a megaarmor. (sector 13)
  2. Open the blue key door and head south-west to the switch, but do NOT press it yet or you will be locked out of this secret. Jump south-west to a radiation suit, then head south into the lava, then take the tunnel going north-east. Take the lift up and keep going north-east until you get a supercharge. (sector 88)
  3. Open the blue key door and head south-west to the switch. Press it, then head north and north-east as the lava rises. You can find a backpack in an alcove to the south. (sector 141)
