Tomb Raider: The last Revelation
Cairo
LEVEL 24: TRENCHES (first time)
You enter this level for the first time from the CHAMBERS OF TULUN level, from the road on the back (north) side of the CHAMBERS. If you are following this walkthrough, you should have already been through the CITADEL GATE LEVEL (first time).
STREET WITH PALM TREE: Drive up to the ledge with the columns and dismount. Pick up Uzi clips on the ledge. Then head down the street on foot to the right (east) toward the big palm tree.
SANDY STREET AND FORTIFICATION: Go through the doorway behind the palm tree to a narrow, sandy street. The chute ahead in the wall is too steep to climb. You'll come through here from the other side later on. Go the left (north) and follow the street to a building with square, white pillars on the right. There's a soldier lurking behind the first pillar. Take him out and continue. When you reach the "T", stop to reconnoiter.
There's a mounted machine gun down the road to the right. To avoid it, run up the street to the left and jump up the sand pile to a safe spot with a large med-pack and Uzi clips. From here you can scope out the location of the gun with the BINOCULARS. Approach the gun, hugging the left wall. When you get a bit closer, run across the street and duck into the makeshift room on the right. As soon as you get behind the low wall of sand bags, crouch. The gun can't track Lara if it can't "see" her. So crawl forward then to the left to get around to the side of the gun while it's still pointing toward the sand bag wall. Stand up and look through the small, rectangular opening. You should be able to see the side of the gun. Use the revolver with the laser sight to target the red spot on the side of the gun. Boom! No more gun.
(NOTE: Regular and explosive arrows don't seem to work here, but if you're playing on the PC and are out of revolver bullets, you can equip the crossbow with the laser sight, then switch to pistols as described in the section on the laser sight bug in the COASTAL RUINS walkthrough.)
Climb onto the sand bag wall, then to the ledge above, where you'll find some super grenades. Hop down, climb up onto the ledge above where the gun was and drop through the hole. Follow the passage cautiously. When you come to a low opening on the right, crawl in. (If you continue forward, you'll run into a flame thrower mounted on a tripod.) Go through the crawlspace, timing your crawl to avoid the oscillating steam pipes as well as you can. Kill the soldier in the next room, taking care to avoid the open flame. (If you like, you can crawl in just far enough to alert the soldier, then crawl back out, crouch and shoot him in the knees with pistols.) The soldier drops a small med-pack, which you'll probably need about now. Shoot the crate to get the wideshot shells inside.
Climb up through the opening in the ceiling for a nice clear shot at the flame-thrower. For whatever buggy reason, you can only snipe at the soldier in the road beyond the gun using the revolver (or pistols using the laser sight but) if you aim for his. . . ahem. . . privates. Or, use the crossbow plus laser sight. (It takes about 8 normal or 3 poison arrows. You probably want to save your explosive arrows.)
Lara, though a whiz at weaponry, can't seem to climb through this little crawlspace. So return through the room below, then the crawlspace with the steam pipes, to the street. Continue past where the gun was, passing underneath a wrecked vehicle, to a "T" intersection.
Go> through the crawlspace on the right, timing your crawl to avoid the steam pipes as well as you can. Pick up the WEAPON CODE KEY near the dead soldier. Crawl back out. Continue straight ahead to a deep pit.
Once you've picked up the WEAPON CODE KEY, the machine gun at the other side of the pit won't fire, so no need to worry. Grab the crevice and traverse around the corner, across the pit, pausing if necessary to avoid the oscillating steam pipe, and around the next corner, where you can drop to a ledge. Kill the soldier lying in wait. Get a large med-pack from behind the machine gun.
Continue west to an OPEN AREA WITH A WRECKED JEEP. When you approach the engine of the Jeep, another soldier comes at you from near the pit. You may want to run out from behind the Jeep, since you can't use the Look button while standing near it (at least in the PC version), and Lara will also target the machine gun, making it more difficult than necessary to kill the soldier. When the coast is clear, stand facing the Jeep's engine and use the CROWBAR to pry out the VALVE PIPE. Duck under the overhang opposite the Jeep and find the wooden crate in the back corner. Shoot it to get the large med-pack inside.
Return the way you came (traverse across the pit, then follow the narrow streets) to the motorcycle.
If you've already been to the CITADEL GATE level and gotten the NITROUS OXIDE CANISTER, you can now combine this with the VALVE PIPE to make the NITROUS OXIDE FEEDER. Position Lara facing the motorcycle (as though she were about to get on) and use the FEEDER to attach it to the bike. Now when you press Sprint key while driving forward, you'll get a power boost.
When you have the two components and have modified the bike with the NITROUS OXIDE FEEDER, you can return to CHAMBERS OF TULUN (second time) to get the ROOF KEY, which you'll need in this level (TRENCHES). (If you don't want to bother going back, there is a way to avoid using the ROOF KEY. See the note below at the **.) You can also go back to the CITY OF THE DEAD (second time) to get the second secret in that level. Once you have everything you need, continue with this level, TRENCHES (second time), below. The walkthrough follows this sequence.
