Chambers of Tulun - Secret #2

After climbing to the upper level of the main building, as shown in the previous section, you can now go after a secret. Take a running jump to grab the small ledge that juts out over the west side of the room.

- OR -

Instead take a running jump to the ledge recessed into the west wall, then a standing jump onto the jutting ledge.

Walk to the edge and take a standing jump to grab the dangling rope.

Slide to the bottom and pivot slightly to the right.

Then swing and jump over to the high ledge on the opposite (east) side of the room.

This is SECRET #2 (57/70). Kill the giant beetle that flies up from the left side of the alcove. A second beetle, which normally spawns when you reach the south ledge, may appear at this time, so watch out. In the patched PC version of the game, this beetle may be invisible, but Lara will still aim at the empty air where it's hovering so you can shoot it. When the coast is clear, pick up wideshot shotgun ammo and a large medipack.
