Xibalba | Walkthrough Deadfall Adventures Guide
Last update: 01 February 2017
Right after the chapter starts, you'll notice that you don't have any weapons. If you go downstairs then you can get a treasure map that's next to the dead mercenary.
Then go even lower and head forward, turn right by the big statue and continue along the way. After a moment you'll reach a place with explosives planted. Use the detonator that's close by and get through the hole you've just made.
After a while you'll reach a puzzle just like the one you've solved earlier. You have to light up two circles at the bottom and three rectangles at the top. Then you'll unlock a door you've passed before. Go back to the place where you destroyed the door with dynamite and go straight.
You'll reach a newly opened chamber, get inside. It turns out to be an elevator, but with a trap. As soon as you see the exit, move to that end and get out as soon as possible. Otherwise spears would kill you.
When you get out of the elevator, enter the chamber and a mummy will appear. Remember that you don't have a weapon. You have to quickly activate three switches on the skulls - the mummy will burn and the door will open.
On the left there will be another elevator with a switch and in front of it, a body of a soldier, you can take his guns. Take them and take the elevator down. Then go along the corridor while killing a few mummies. At the end of the corridor you'll see another switch. Use it to make all walls disappear and puzzle will show up.
Just shoot the turning switches to move the elevator up. Do the same thing when you're on the halfway.
When you're higher, get out of the elevator and walk up to the door with a little window. Shoot another switch to go higher. Enter the corridor and keep going.
At the end of the corridor you'll have access to one of the mirrors. Using it, light up one of the crystals below and you'll unlock the stairs. Go along the unlocked way to another mirror and kill some mummies.
When you reach the next mirror, turn it so it lights up another crystal and keep going next to it. A passage will open and more mummies will appear. The best way to get rid of them is using a shotgun and a trap that you'll see there.
After a while you'll reach three levers and a wheel. You have to turn two statues and a medallion above them like your notebook shows you. So the statues must face each other and the medallion has to face you. Try using the levers to understand how they work.
When you do it, a cutscene will start and a way through will unlock on the right side. Go along it. A lot of mummies will appear again, but you can easily defeat them with the traps. At the end of the corridor another cutscene will appear and you'll be able to jump down.
You'll witness a fight between the mummies and the mercenaries again. You have to kill them all to continue the storyline. When you do it, you'll see another puzzle. Go to the bridge in front of a giant burning skull and shoot the eyes of two masks on your sides. Another cutscene will occur.
A bridge will open. Go get the professor.
In the first part of the fight he'll shoot you with a rocket launcher and throw grenades. The strategy is simple, you just have to avoid his attacks and shoot him back. If you run out of ammo, there's a crate in one of the corners. It's not very challenging except that you have to move all the time.
When you hurt him enough, the second part of the fight begins. He'll summon two immortal mummies and become immortal himself. Don't mind them and pick up the rocket launcher that should be close by. You have to destroy four columns that support the temple to defeat the enemy. The crosshair turns red when you aim at them. When you destroy all four, you can relax and watch the final cutscene.
