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.
