Obelisk of Khamoon - Slides-Into-Steps Room (Second Visit)
and Seal of Anubis Switch
Re-enter this room from the OBELISK/DRAWBRIDGE area.
Climb the long row of block steps to reach the upper left side of the room.
If there's a slope here instead of steps, then you missed a switch. Return outside to the OBELISK/DRAWBRIDGE area. Turn right, and go up the stairs to the northeast corner. Use the switch there (also shown in the first screenshot, above) to change the slope into steps. Then return here and climb up.
At the top of the block steps, turn right and take a running jump to grab the narrow horizontal crevice high on the east wall. Traverse to the right and drop onto the golden blocks.
Go around to the far side and drop down onto a ledge at the base of another long slide. Enter the small room ahead...
...and throw the switch to change that slide into steps.
Climb the block steps just outside the switch room.
Another mummy (14) waits in the room above. To kill it safely, stand on the highest block step, draw pistols, and jump in place.
When Lara locks on, hold Action, then keep jumping and firing until the mummy explodes.
Climb up into a room overlooking the entire OBELISK WITH FOUR DRAWBRIDGES area. Pick up a small medi pack (22) behind the silver )O( ornament (plus a save crystal in NG+). Then use one switch to lower the BRIDGE TO THE SEAL OF ANUBIS...
...and the other switch to open the gold door next to it.
NOTE: You can now take a shortcut to the second and third secrets if you like. Doing so will save less than a minute but cost half Lara's health. Both the shortcut and the slightly longer, low-damage paths are covered in the next section.
DARK MODE: Even with brightness adjusted, dark images on a light background can be hard to see. May I suggest a reputable dark mode browser extension, such as Dark Reader? (Download only from trusted sites, like darkreader.org or your browser's web store.)
