This is a continuation of the "TALL ROOM WITH POOL AND LEDGES" section in the main walkthrough. See here for Part 1.

Climb onto the ledge above.

This next jump is a little tricky, so you may want to save the game. Stand at the edge of the ledge with the protruding corner of the wall on Lara's left. Then take a standing jump to the next ledge. (You could also use a carefully angled running jump here, just be sure to press Left and Action while Lara is in the air in order to stick the landing. Otherwise it's easy to overshoot the edge and fall onto the ledge below.)

Now take a carefully angled running jump onto the ledge with the sleeping cobra. Take care to land on the left side of the ledge so the snake doesn't bite you. (Sorry for the bad screenshot here. It's hard to get a good angle with Lara squeezed into the corner.)

Turn to face the cobra and then hop back against the wall to put a little distance between Lara and the snake while you shoot it.

Move to the corner of the cobra ledge and take a standing jump to the next small, square ledge.

From there, jump into the doorway and immediately run forward and around the corner to avoid being flattened by a rolling boulder.

Alternatively, jump into the doorway. Then immediately hop back...

...and grab the doorsill. Wait there until the boulder rolls overhead and drops into the pool. Then pull up.

Move carefully past the poisoned darts and slicing blades or simply crawl under them to the edge of the pit lined with sharp blades.

Pick up the small medi pack around the corner on the left. To jump across the blade-lined pit either take a standing jump from one edge to grab the other and pull up, or take a running jump, being extra careful not to back up into the slicing blades beforehand.

NOTE: You may notice a crawlspace at the bottom of the pit. There's a secret down there, but ignore it for now. You'll return this way in a few minutes.
