TRENCHES (second time) After getting the ROOF KEY in the CHAMBERS OF TULUN level, and the components for the NITROUS OXIDE FEEDER, you can proceed in this level. From the STREET WITH THE PALM TREE (near the level entrance), go on foot up the street to the northeast. Near the stairs you'll see an alcove on each side of the street. Climb into the one on the left and get a large medipak. Cross to the alcove on the other side of the street. There's a sniper on the opposite rooftop (above where you got the medipak). You can take him out from here or wait until you get up on the ROOFTOPS. Open the trapdoor above the lower part of this alcove by standing at the edge facing it and jumping straight up to grab the switch. Climb through the crawlspace above to drop into the small room beyond. Pick up a quiver of poisoned arrows. Go through the next crawlspace to an opening above the STREET WITH THE PALM TREE. Turn right, crawl up the ramp a little ways, draw pistols while crouching, and shoot the gray block obstructing the crevice. Drop back and grab the edge of the opening. Traverse to the left (this isn't possible without first destroying the obstacle) and around the corner, and drop onto the ledge. Use the overhead bars to traverse above the street to the opening on the opposite building. Use a medipak beforehand if necessary, since a swarm of locusts attacks on the way. ROOFTOPS: Enter the next area cautiously so you're not ambushed by the soldier inside on the left. He drops a small medipak when he dies. Use the ROOF KEY to unlock the doors in the corner. Go through to another ledge above the street. Take a running jump to grab the horizontal crevice on the next building. (Aim for the right end, where there's no overhang.) Traverse to the left until you can pull up. Climb up the blocks to a small, rectangular opening. If you didn't kill that sniper earlier from below, he'll start shooting at Lara through the opening, and you'll need to take care of him. Look through the opening and locate the electrical box across the street. The crossbow fitted with the laser sight works well here. Hit the red light squarely and one normal arrow should do it. Or, you can use the pistols and just keep firing. (Lara won't auto-aim, so you'll have to turn her until she's shooting in the right direction.) When the box starts to smoke (as shown in this screenshot), you'll know you've disabled it. This opens a door elsewhere. Return to the opening above the street and safety drop to the ground. TWO STAIRWAYS AND LONG JUMP TO STREET BAZAAR LEVEL ENTRANCE: Get back on the motorcycle and drive around the corner to the northwest. You'll see two sets of stairs leading up to the north. To clear the area, first drive up the stairs on the left. Run over a soldier at the top and continue downhill, running over another soldier at the bottom. Notice the huge pile of sand. At the top of the pile is a ladder. You can't reach the ladder on foot since the sand pile is too steep. But, in the corner to the right of the pile is the big door you just opened by shooting the electrical box. You can jump the motorcycle through here: Ride back up the hill to the two sets of stairs. Set up a long, straight run from the top of the hill up the left side of the right stairway. Use the nitro boost (Sprint key) for extra power. Race up the stairs and through the door you opened, landing on top of the sand pile. (IMPORTANT: Later on, you will return to this area through the small, silver door in the corner. Be sure not to park the motorcycle in front of that door or you may have trouble getting through.) Dismount near the small closed door and climb the ladder to the STREET BAZAAR level.
