Cenote – Ancient Gate with Water Wheels and Spigots
West Side (part 1)

While standing in the area where you dug up survival cache #8, look across the pool toward the doorway with the green orb, and you'll spot one of the Yaaxil lurking there. You can shoot him from a distance or explode the orb to set the enemy on fire.

Swim across to that area, collect some cloth, mushrooms, and herbs, and loot the corpse. When you enter the room where the enemy came from and start up the stairs to the right...

...another enemy smashes through the wooden wall ahead and attacks. Blast him with the shotgun, a flare round from the pistol (if you've unlocked the Serpent's Glint skill), or use the Puma's Feint/Dodge Kill as described in the previous section.

When you've killed that one, a third enemy also approaches from the north. Take care of him.

Then turn around and pull down the effigy (4/5) in the southwest corner for the Respected Challenge.

NOTE: The annotated level map shows the Cenote Tomb Base Camp here, but it does not appear until you've finished the level and moved on. It will allow you to fast travel back to this area later in case you miss any collectibles.

Turn around again and move up the first set of steps to the north.

On the right is a wooden barrier you can pull down with a rope arrow. This isn't strictly necessary, but it'll make it easier to swim back to this area if you fall in the water later. There are also a few resources at the bottom of the pool here.

At the top of the second set of steps is a winch and several columns, one of which has shotgun, handgun, and rifle ammo arranged around its base. Grab what you can.

Stand near the winch and face south. Notice the 3 golden spigots shaped like serpents' heads. Each has a rope coil that you can tether to the winch in order to turn the spigot, but the the coil on the upper level is blocked by debris. The goal is to move the spigots to direct the flowing water down to the water wheel below.

Start by shooting a rope arrow into the coil on the middle spigot, tethering it to the winch.

Then crank the winch to rotate the middle spigot so it faces right.

Follow the wooden walkway along the right wall toward the end of the spigot you just moved.

As you near the green orb, another Yaaxil emerges from the opening next to it. Blast the enemy or the orb, or use the Dodge Kill maneuver.

Then continue to to the end of the walkway. Jump to grab the spigot you just turned and pull up.

Climb onto the ledge above...

...and use your axe to clear the wooden debris from around the upper spigot.

When you finish, another enemy charges from ahead on the right. Deal with him.

Then go into the area where he came from to find a resource canister.

Turn around and drop down on the right, behind the upper spigot...

...to find another resource canister. From there, you can drop down once more into the room where you shot the first Yaaxil and pulled down the effigy.

Then return up the stairs to the winch.
