IMPORTANT: Levels 21 through 26, set in Cairo, are interconnected. Some backtracking among them is needed to find all the necessary items. This walkthrough covers what I hope is the most direct route including all kills, pick-ups, and secrets. I have also included a CAIRO OVERVIEW outlining the basic path through the levels. This chart contains minor spoilers, such as keys and puzzle items, so you may want to avoid it unless you get lost/confused. The walkthrough also contains notes on what to do if you missed any crucial items.
LEVEL 22B: CHAMBERS OF TULUN (revisit)
Kills: 4 Items: 3 plus Torch and Roof Key Secrets: 0*
NOTE: There are 2 secrets in this level. Both are covered in the CHAMBERS OF TULUN (first visit) walkthrough, but it is still possible to get them now.
PREVIOUSLY ON "LARA'S ADVENTURES IN CAIRO": If you've been following this walkthrough, you have already passed through this level twice. The first time you trapped or killed the Minotaur in order to reach the entrance to the CITADEL GATE. After obtaining the NITROUS OXIDE CANISTER in the CITADEL GATE, you passed through the CHAMBERS OF TULUN a second time in order to get the motorcycle and drive it into the TRENCHES. In that level you obtained the WEAPON CODE KEY and VALVE PIPE. Then you combined the NITROUS OXIDE CANISTER and VALVE PIPE to make the NITROUS OXIDE FEEDER, and attached it to the motorcycle in order to give it a turbo boost. Now you have returned to the CHAMBERS OF TULUN a third time. If you missed any of these crucial items, check the CAIRO OVERVIEW and the footnotes on revisiting earlier levels.
PREVIOUSLY UNREACHABLE AREA IN THE NORTHEAST CORNER: Now that your motorcycle has the nitro upgrade, you will be able to go much faster and jump much farther. From the back entrance to the CHAMBERS, turn left and drive around the building toward the deep pit, but do not jump across the pit at this time. Instead make a U-turn. Line up the motorcycle facing the right side of the broken staircase. Drive up the stairs and hold Sprint/Dash to activate the nitro. This will allow you to make that long jump into the opening in the top right corner of the building, which would have been impossible before. (screenshots)
Dismount and climb into the doorway on the left. Then turn right and enter the building through the yellow-and-white door, which is now open. Take out the soldier waiting inside. Continue forward and slide down the ramp. (screenshots)
ROOM WITH RED SPRINKLER HEADS AND CONVEYOR: Go straight through this room into the short passageway opposite the ramp. Turn right and kill another soldier guarding a small room with a couple of storage crates. Pick up the WOODEN TORCH on the floor in the back left corner. Then return to the room at the bottom of the ramp. The yellow-and-white door up on the ledge does not open yet, so head down down the slightly less steep ramp just to the right of the one where you entered. (screenshots)
Just before you reach the second landing, press the Draw Weapons key twice to toss the torch down onto the landing and pull out your guns. Then round the corner and kill the soldier who approaches from the next room. Retrieve the torch from the landing and go through the doorway where the last soldier emerged. Ignore the ladder on the right, which leads back up to the street. Instead go into the short passageway on the left. Drop the torch here and press Action to kick open the gray door. Draw weapons and run inside and around to the left to take out another soldier. Retrieve the torch and light it on the flaming sconce mounted on the wall. (screenshots)
NOTE: If you explored this area on your first pass through this level, the gray door will already be open and the soldier dead. However, none of the yellow-and-white doors opened at that time, so you'll still need to deal with the other soldiers and do the business with the torch.
Carry the lit torch up the ramps to the ROOM WITH RED SPRINKLER HEADS AND CONVEYOR. Go up the ramp on the east side of the room to the ledge below the sprinklers. Stand beneath the first sprinkler head and press Action to use the lit torch to set off the sprinklers. This also opens the remaining yellow-and-white doors. Drop the torch (you won't need it again) and go through the door between the sprinklers. Follow the passageway forward and left, then use the lever. (screenshots)
Cutscene: The conveyor starts up, hooking a storage crate and depositing it in the next room.
NOTE: Setting off the sprinklers also opens the last yellow-and-white door in the area at the bottom of the ramps where you lit the torch, but there's nothing there.
Return through the SPRINKLER ROOM to the room to the north, where you found the torch earlier. The crate that came in on the conveyor is now stacked on top of one of the others. Climb on top of these crates and take a running jump to grab the high ledge. Pull up and drop down into the next room. (screenshots)
STORAGE ROOM: All but two of the storage crates can be broken by shooting them. (Crouch to hit the smaller ones.) Inside you'll find a small medipack, normal arrows, and wideshot shells. Shoot the padlock on the barred door to break it. If you stand on the low step near the door and crouch, you can use pistols. Reach into the niche in the barred alcove to get the ROOF KEY. (screenshots)
Climb back over the wall into the room with the stacked crates. Follow the passageway back to the SPRINKLER ROOM. Climb onto the ledge near the sprinklers. Then exit through the yellow-and-white doors onto a ledge overlooking the street. Turn left here to get back to the motorcycle. (screenshot)
NOTE: If you accidentally drop off the ledge into the street before getting the motorcycle, you can climb back into the building through the opening at the lower left. (screenshot) Then climb down the ladder into the area where you lit the torch and follow the ramps back up to the SPRINKLER ROOM.
Drive the bike back over the sloped ledge to the street. (screenshot) If you brake on the way down, you can avoid taking damage, but don't worry if you do. When you change levels, Lara's health will reset.
Now that you have the nitro boost for the motorcycle, you can reach the second secret in the CITY OF THE DEAD. To get back there, follow the street to the south, jumping the bike across the deep pit on the left side. (screenshot) Then continue around to the south side of the CHAMBERS. Turn left and ride up the hill to re-enter the CITY OF THE DEAD.
REVISITING THE CHAMBERS OF TULUN: You will return to TULUN once more before completing the Cairo section. This is covered during the CITY OF THE DEAD (revisit). Check the CAIRO OVERVIEW for additional details.
*NOTE ON SECRETS: There are 70 secrets in the entire game. To check your progress, press Pause (P on keyboard, Start on PlayStation or Dreamcast controller) then choose Statistics. There are no secrets in this section, though you can still obtain #56 and #57 if you missed them the first time. See the CHAMBERS OF TULUN (first visit) walkthrough if you need help. At this point, you should have 58/70.
†UPDATE HISTORY: 5/5/19 - First major update since this walkthrough was created in 1999. This revision includes many new screenshots as well as various other corrections and clarifications.
ACKNOWLEDGEMENTS: Special thanks to the participants in the alt.games.tombraider newsgroup and the old tombraiders.com forum, without whom parts of this walkthrough could not have been written. Thanks also to Eric and Sturm, who sent in corrections for this level.
TO CITADEL GATE - NITROUS OXIDE CANISTER: From the back entrance to the CHAMBERS (near the road leading north to the TRENCHES), follow the road to the west on foot, avoiding the Minotaur if you didn't destroy him earlier. Turn the wheel to open the wooden door. Go through, climb the ladder, and follow the passageway to the CITADEL GATE. If you need screenshots or help with the Minotaur, follow the CHAMBERS OF TULUN (first visit) walkthrough. Then follow the CITADEL GATE walkthrough, which explains how to locate the NITROUS OXIDE CANISTER and return to the CHAMBERS OF TULUN. You can then continue with the walkthrough from the top of this page.
TO TRENCHES - VALVE PIPE and/or WEAPON CODE KEY: From the back entrance to the CHAMBERS, get on the motorcycle and follow the road north into the TRENCHES. Refer to the TRENCHES (first visit) walkthrough to locate the missing item(s). Combine the NITROUS OXIDE CANISTER and VALVE PIPE to make the NITROUS OXIDE FEEDER, attach it to the motorcycle, and drive back into the CHAMBERS OF TULUN. You can then continue with the walkthrough from the top of this page.
