Yellow keycard
Go through the door and kill the zombies and imps waiting in the corridor. Head through the west door and follow the passage past a number of monsters and down a staircase, going round the corner to see a lava pit on your right - on Hurt Me Plenty (HMP) skill level or higher, revenants will be guarding the square platforms across the pit. Keep following the path until you reach a junction, then turn left to kill some nightmare imps. Go through the west door to find the yellow keycard guarded by an arch-vile.

Red keycard
Leave the room and go through another door on your right to enter a storeroom. Take the items in this room, including armor and a super shotgun, then press the switch in the north-east corner. Leave the storeroom again and return to the lava pit to find that three platforms have risen on the south side of the pit, allowing you to step across to a structure with a switch. Press the switch, which is one of two needed to reach the red keycard, then backtrack to the starting corridor.

Go through the north-west door and turn right to kill a pain elemental, then open the nearby bars with yellow key markings and turn left to face the enemies ahead - spectres on HMP or lower, or nightmare spectres on Ultra-Violence (UV) and Nightmare (HM) skill levels. Go round the corner to slay one or two barons of Hell, then go through the door to a square arena guarded by Hell knights and overlooked by imps and nightmare imps.

Take the rocket launcher in front of you if you need it, then grab the Doomsphere in the center of the room which will cause one or two mancubi and arachnotrons to appear. Kill these enemies to open the north and east doors, then kill the plasma zombies and spectres waiting behind these doors. Go through either door and follow the passage, which is guarded by barons on HMP or higher, until you reach a staircase going north-east. Kill one or two Lords of Heresy waiting at the top (along with nightmare imps on HMP or higher) and press the switch that the lords were guarding.

Pressing the switch opens the west door in the square arena, and also opens a chamber at the bottom of the stairs containing shotgun guys. Kill them then return to the arena, killing the nightmare cacodemons and nightmare spectres waiting behind the west door. Go through the door and press the switch in the west wall, which will lower the floor next to it and reveal a crawlspace - crouch down to enter the crawlspace and follow it south and west until you drop into a storeroom. Take the minigun then press the switches in the south-east and south-west corners.

The south-west switch will open a crawlspace on your right - follow it back to the room where you found the yellow key and pass through the door to get back to the lava pit. Slay the cacodemons that have appeared here, then step across three platforms have risen on the north side of the pit to reach the switch that will allow you to get the red key. Backtrack to the starting corridor, slaying several barons that have appeared on the staircase, and go through the north-west door again then head west through a smaller door and follow the steps down to the red key. Taking it will cause two afrits to appear at the top of the steps.

Blue keycard and exit
Kill the afrits then return to the starting corridor and go through the door in the north-east corner which has red key markings. Head north through another door and take the blue keycard sitting in a pile of corpses, then go back the way you came and pass through the red key door that closed behind you. You will find that you are now in a hellish environment of rocks and lava, overlooked by imps; turn left or right and follow the path round to its south side to find two to four hectebi waiting for you.

Hectebi behave similarly to mancubi but have more health and give no warning before they attack, so be ready to dodge their fireballs at a moment's notice. Once all the hectebi are slain, the bars blocking the door at the south end of the hellscape will lower - open the door behind them to find yourself back in the Triton base, then follow the corridor and open the wide silver door at the end to find a large hall. Kill the chaingunners and plasma zombies then try to open the door in the north wall.

A spiderdemon will be revealed behind you - use the pillars around it for cover and take the plasma gun by the east wall if you need it. Once the spiderdemon has been killed the north door will open - go through it and kill the nightmare imps guarding the staircase, then climb to the top and step on the marble teleporter to finish the level.

Secrets

 * 1) From the starting corridor, head through the west door and follow the passage to a staircase with a ledge above it. Jump on to the ledge and open the middle section of the south wall to reveal a light amplification visor, a partial invisibility and two energy cells. (sector 577)
 * 2) Before going down the steps to the red key, open the tech panel in the north wall to reveal a switch. Press it, then quickly head east through the door and north through a set of bars (which require the yellow key) to find an open door ahead leading to a small chamber. (sector 288) Take the armor, then press the switch in the north-east corner to open a nearby niche containing an energy cell pack and (on HMP or higher) a plasma gun.
 * 3) After pressing the switch guarded by one or two Lords of Heresy, look at the west wall to see a purple computer screen. Shoot this screen with any impact weapon to reveal a low passage containing a backpack and many health bonuses. (sector 308)
 * 4) After entering the crawlspace leading away from the square arena, go straight ahead at the first junction and go round the corner to find a megaarmor. (sector 169)
 * 5) After opening the crawlspace leading back to the yellow key chamber, go into the crawlspace and turn right at the junction to find a soulsphere. (sector 168)
 * 6) In the hellish area, go to the south side and look at the north wall to see that part of the wall is in shadow. Open this wall to find a marble room containing a megasphere and a BFG9000, which are guarded by nightmare imps. (sector 498)
