ROOM WITH SQUARE PILLARS AND FIVE SWITCHES: Here you see a number of tall square pillars, a high platform with 5 switches, plus several doors. When all the apes are dead, enter the room. You can probably shoot them from the doorway by advancing to draw them out then backing up. Three more gorillas there need your attention. Go up, turn left and continue to a large room. Then return through the long passage to the north (the way you came) to the base of the stairs. Behind the building is a narrow alley with a gorilla and 2 sets of magnum clips in it. Pass it and continue to the other end of the room.
Turn around and head back toward the hallway where you entered. You'll get to the top later on from above. The sound of running water here suggests that this structure is actually an aqueduct. Kill 4 bats there and pick up a small medi pack on the floor on the left. When they're dead, continue to the far left end of the room where it's darker. You can also climb up on one of the low blocks near the entrance where the lions can't reach. If you go in slowly, you can probably draw them out one at a time. Give yourself room to back up while shooting at the 2 lions that emerge from the second to last alcove. ROOM WITH MANY ALCOVES BELOW AQUEDUCT: Advance slowly to the left with weapons drawn.
NOTE: For more information about the Minoan dolphin fresco in this room, as well as many other real-world items and locations featured in the games, check out the Artefactual series from Tomb Raider Horizons. Instead turn right and follow the long passageway to an open area with a tall building. Kill the crocodile in the hallway and continue to the base of a stairway. For now, draw weapons and head through the doorway on the north side, the same side as the underwater gate. There are three side passages leading out of this room at ground level (and more up above). Keep swimming, surface in a lovely pool decorated with dolphins and climb out of the water. The fourth door leads to the level exit, where you'll use the three gold bars to open the final door. The three lead bars must then be turned into gold by a magical process, which you must discover. Three of the doors lead to areas where you'll find lead bars. OBJECTIVES: Find the room with the five switches and use these in different combinations to open four different doors. Then hold Action (hand icon) to hang on as you traverse and release it to let go. You'll need to turn off auto-grab in the Controls menu. NOTE FOR iOS/ANDROID GAME: If you've come searching for help to drop down after traversing along a ledge or crevice, this seems to be a bug, but fortunately it's a minor one. Also note that one of the regular pickups in this level will be the MAGNUMS if you didn't find them earlier. See the section on the ROOM WITH SQUARE PILLARS AND FIVE SWITCHES, below, and the note at the end of the walkthrough. * NOTE: One of these pickups can only be had by cheating.
