Tomb of Tihocan - Tomb Entrance, Atlantean Centaurs, and Pierre
(Again with All Kills and Pickups)

NOTE: In addition to the basic strategy shown here, There are a few details and alternate centaur strategies in a footnote following the main walkthrough.

After unlocking the "On Incredible Tales" achievement/trophy, as described earlier, reload the save you made outside the tomb. Now we need to kill those centaurs. Climb out of the water on the right side of the ledge.

Draw weapons and run toward the statue to the left of the entrance to bring the first Atlantean centaur (15) to life. If you approach at a slight angle, from the right side of the ledge, as shown here, you should have plenty of room to maneuver.

When it animates, start firing as you backflip away twice. (The centaur on the right does not animate yet.)

Side flip to the left...

...then back to the right. Then just keep leaping from side to side while shooting. The centaur will continue to hurl fireballs, but as long as you continue jumping, these will almost never hit Lara.

Once you've depleted its health, the centaur explodes, and you can continue into the tomb. (In NG+ you'll find another save crystal in the sandy area to the left of the tomb, in case you want to save again before taking on Pierre.)

Inside the building, move past the red pillars and take on Pierre (16), who appears on the far side of this large room.

This time, you can use the magnums or shotgun to take him down fairly quickly. Or, if you'd rather use pistols, run forward, get a lock on him, and keep firing as you backflip away. Then flip from side to side while firing continuously. As long as Lara keeps moving, most of Pierre's shots will miss. Or, run/jump straight past him, roll, and shoot at his back until he turns around. Repeat until he falls.

If this is your first time defeating him, the achievement/trophy "Not So Late for the Prize Giving!" should pop. Relieve the corpse of a SECOND GOLD KEY (21), the SECOND PIECE OF THE SCION (22), which he apparently took from the pedestal at the center of the room, and his MAGNUMS (23), or magnum ammo if you already have the guns.

If you want all kills, return to the tomb entrance to awaken the second centaur (17).

It's easy enough to kill it with pistols from the safety of the doorway. It won't come inside. Just get a lock on it, hold the Action button...

...and side flip out of the way whenever it launches a fireball.

Repeat until it explodes.

Return to the main room and use the square blocks to climb onto the ledges on the east and west sides of the room to pick up 2 sets of magnum clips (24-25).

Then jump over to the balcony at the north end. Pick up the large medi pack (26) behind the balustrade on the left. Use the GOLD KEY you lifted from Pierre in the keyhole in the middle of the north wall to open the door on the south wall.

Drop down and enter Tihocan's final resting place to finish the level.
