After using the switch to open the THIRD GOLD DOOR, as shown in the previous section, drop into the pool and retrieve 2 sets of magnum clips (46-47) on the bottom. (In this screenshot, Lara is treading water in the southwest corner, opposite the switch. The ammo is almost directly below.)
Now approach the 2 underwater levers. These open each of two red webbed doors nearby. They are on short timers and they're set up so that if you open one door and then the other, the first one closes. Pull the left lever first and go through the left door.
Pick up some Uzi ammo and shotgun shells (48-49).
The door closes behind you after a few seconds but reopens when you approach the shotgun ammo. Swim back out to the levers and get air.
Next, pull the right lever and go through the right door.
Pick up more shotgun shells (50) sitting on a tan block. Then continue along the passageway, forward, right...
...then right again, to find some magnum ammunition (51). If you're running out of air, leave the ammo for now and continue forward and around the corner to the left.
There's an opening in the ceiling just above the fleshy block. Take a breath, then go back for the ammo. Then return to the air hole to continue. (Note the location of other webbed door near the fleshy block.)
NOTE: The webbed door back at the two levers closes behind you but re-opens once you pass the shotgun ammo. You don't need to go back there, but you can if you want to.
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.)
