Note: This walkthrough is for the two-player version of the game. For Single Player please go to: Pyramid of Osiris (Single Player)

First Steps

Shoot the vases in the corners left and right to obtain some gems. Head across the bridge. On the other side Lara or Carter can use the torch (PS4: L1; Xbox: LB.) to light the two braziers. Before you head up the two large squares that are raised from the ground, you may want to collect more gems in the chambers to the left and to the right. Upstairs are more vases with gems. Once everything is collected use Osiris' Staff to shoot at Set's Mark, the golden glowing orb. The orb vanishes and the door opens. Step through.

The Rotating Eye

In the next room you can light four more braziers, this time to get gems or other goods and break more vases. After you've collected all you want, have each player step on the pressure pads. The eye in the pit in the middle of the room will extend upwards and spears will extend from the ground separating you from your partner(s). The eye will fire at one of the players. Have him evade the fire bolt and return fire to hit the eye. The eye will turn towards the next player, who has to shoot it again. When every player has shot the eye, it explodes and the path opens. Continue onwards to be confronted by Set.

Sets Army

Shoot at the three skeletons attacking. Then light the brazier and collect all gems.

Red Skull (1/5):
Use the Staff of Osiris to shoot at Set's mark on the left side of the room before continuing onwards. This will open the barrier to the alcove with the Red Skull. Pick it up.

Next step onto the square platform with the Osiris glyph on the right side. Use the Staff of Osiris to raise it and all players standing on it. Jump to the upper walkway. Three more skeletons will attack you. Kill them and then once again clear the area of gems from vases and fire braziers. Afterwards use Lara's or Carter's grapple to get all players to the level above. (Either grapple up and pull all others up from above or span the rope and let all others tightrope-walk up before grappling up yourself.) Now have one of the Egyptians stand against the back wall and extend the energy shield, have a player with grapple stand on the shield and use it to jump up to the higher level. Use the grapple to get all other players up the wall, too. Here you will be attacked by scarabs. Kill them and then you can once again light braziers and shoot vases. You may also find a medkit.

Red Skull (2/5):
Step towards the left edge and grapple down to the Red Skull. (Have one player stand on the edge and hold to rope while the other grapples down.)

Now have one of the Egyptians stand on the upper edge of the room and extend his shield for Lara (or any other character) to stand upon and climb up to the higher level. Before stepping on the pressure plate to open the next door, bomb the two sarcophagi on the left for gems. (To use a bomb, stand where you want it placed, press the button for the bomb, leave the bomb radius and press the button again to detonate it.) Get back down and step through the opened gate.

Dart Emitters and Bombs

Dodge roll under the flying arrows. (Please note that these are not part of the arrow trap challenge.) In the next room there are again sarcophagi to bomb.

Challenge: Free a Skeleton from its sarcophagus
One of them might contain a skeleton for the challenge "Free a Skeleton from its sarcophagus".

Notice the glowing part of the floor when you come up the stairs just on your right. Use one of your bombs to destroy the floor panel and get to the gems. Two more of these spots can be found in this section, one near a pillar on the left and the third one also on the right, close to a tall burning torch right of the exit. There are also more sarcophagi (near the start) and two medkits (near the exit) on the left. Next use your bomb to destroy the dart emitters blocking the door.

Challenge: Destroy all the tomb's Arrow Traps (1-5/35)
Destroy all five dart emitters for part of the challenge.

Step though the opened path.

Spike Pits

In this next part you will be attacked by skeletons and scarabs.

Challenge: Knock three Skeletons onto spikes with your Remote Bombs
Here you can attempt another one of the challenges. Use your bombs to try and catapult the skeletons into the spike pits. You have to get three skeletons to land on the spikes. You will get more opportunities to try this throughout the level, but I recommend to try to get at least two here. You can restart the checkpoint and hope they respawn if you fail. Make sure that you do not have any items equipped that make your bombs more powerful, otherwise skeletons may get destroyed before being catapulted into the pit. The bomb radius won't matter.

Once all enemies are dealt with, you may light braziers and destroy crumbling floor tiles to get more gems. Afterwards use the grapple and attach it to the ring across the spike pit. Have another character (or all except the one providing the rope) walk across the rope to the other side. Have the one who walked across then run up the stairs to the part on the left and stand at the edge. Use the grapple with this character providing the anchor to get over to the other side.

Upgrade:
Collect the Max Health Upgrade on your way up.

On the next level there are more braziers and vases.

Challenge: Destroy all the tomb's Arrow Traps (6-8/35)
More importantly there are three more arrow traps here that have to be destroyed for the challenge.

Afterwards use the staff to hit Set's Mark which opens the next door.

Head down the stairs where not only two health kits but also a Vulnerable Iron Ring of Strength are waiting for you. Use a bomb and shoot the vases to free the gems. Head down the stairs to be greeted by more arrow shooters. Jump across the gap to the right and destroy the traps here.

Challenge: Destroy all the tomb's Arrow Traps (9-11/35)
Destroy all three traps.

Challenge: Knock three Skeletons onto spikes with your Remote Bombs
You also get another chance to knock a single skeleton into the spikes, if you don't have three already. Place your bomb so the immobile skeleton on the same platform as the three arrow shooters is within its radius. Detonate it so the skeleton is catapulted into the spikes. Once again: Remember not to raise the bombs power. Be warned: If you do not catapult the skeleton off the platform, towards certain death, it may awaken.

Next have one of the Egyptians raise their shield and walk along the path towards the next arrow shooters. Evade them to the left and then jump across to destroy them.

Challenge: Destroy all the tomb's Arrow Traps (12-14/35)
Once again destroy all three traps.

Challenge: Knock three Skeletons onto spikes with your Remote Bombs
And there is also another immobile skeleton here, in case you are still missing one.

Once the path is safe you may want to clear the vases and open up the floor panel for gems. Then jump across the gap to the platform on the right. Once again use the shield to approach the arrow shooters. You will be surprised by a horde of seven (?) skeletons. (By now you should have completed the skeleton challenge, if not, go wild with bombs.) Then jump across to the arrow shooters and use a bomb to destroy them.

Challenge: Destroy all the tomb's Arrow Traps (15-17/35)
Destroy all three traps.

Shoot vases and destroy the floor for gems.

Red Skull (3/5):
Stand on the pillar with the Osiris glyph and raise it with the staff to reach the next red skull. (Or do it like we did in our "Let's Play": raise the shield, have the other character stand on top and simply jump up.)

Now jump across the gap and find the gate closed. Hurry past the flying arrows. (In replay you may use a rocket-launcher or similar to destroy these traps by the way.) Have Lara (or Carter) attach the grapple to the golden ring and walk across the rope with another character.

Challenge: Destroy all the tomb's Arrow Traps (18-20/35)
Have him destroy all three arrow shooters.

Step onto the pressure plate to open the gate. Step through.

Crumbling Bridge

Run across the bridge and jump the gaps till the cutscene starts. After the scene keep on running and jumping till you reach the walled passage. Here you can take it a little slower, use bombs on the sarcophagi, jump over the first spike roller, dodge under the next set and jump across the single one at the end.

Fire Balls Puzzle

In this next chamber you have to get two balls onto the starting platform, it does not matter if you begin left or right. Collect the crystals lying around, placed on pillars or hidden in braziers or vases whenever you like.

Go down the stairs on the right. At the end of the walkway you will find a fire ball. Roll it up the stairs and into the receptacle.

Now head over to the left.

Red Skull (4/5):
Approach the spiky pillar on the left and have one of the Egyptians raise the shield. Jump onto it and up onto the column to reach the red skull.

Now either raise the shield while standing near the right spiky column or stand on the square with the Osiris glyph to raise the platform. Either way jump on top of the spiky column and from there towards the upper level. Push down the flaming ball. Now just like with the first move this up the stairs to the receptacle.

Once both balls are placed the walkway will be extended. Collect the Submachine Gun. Then head across. Three flaming skeletons will come down the stairs. Fight them as well as the countless scarabs. Then head up the stairs. Don't forget to loot vases for gems. At the top use your bombs to search the sarcophagi. Near the one at the end you can find an amulet, the Iron Fire Flail. Head down to the left, there are more sarcophagi - sometimes with skeletons inside - to destroy and gems to collect. Climb up onto the next level on the right and you will raise a new kind of enemy: firebolt-shooting skeletons. Evade their projectiles while shooting them. They will soon be joined by more regular skeletons and scarabs. After all enemies have been dealt with, attach the grapple to the gold ring and have another character walk up to the top. Then stand on the left where there are no spikes and grapple up with the help of your partner.

Red Skull (5/5):
Approach the column and have one of the characters with shield raise it to give the other one a leg up. Collect the final Red Skull of the level.

Next use the shield and grapple tactics on the wall to get all characters up to the next platform. Collect the gems and then have everyone stand on the square with the Osiris glyph before raising it upwards to reach the top. Collect the three gems on the left edge before running to the right.

Ammit Chase

Now Ammit will be chasing you so continue running. Please note that rolling will make your character move faster. Collect gems at your own risk. First you need to jump over a spiky barrel trap, than roll under one, than jump one again and roll under the next before you come to a spot where you have to evade two moving spiky columns.

Challenge: Destroy all the tomb's Arrow Traps (21-23/35)
On the left a set of three arrow shooters comes up. Make sure you've gained a good headstart by rolling and then quickly use a bomb (or if you're in replay a rocket launcher or similar might work better for you; I'm a bomb person, but my partner preferred the heavy weapons) to destroy all. (Since they keep alternating left and right during the chase scene, it is probably best to play this with at least two players so one can take care of the arrow traps on the left and the other of the ones on the right.)

Next you will have to evade first a moving spike column, then a pit with a moving spike roll and another moving spike column.

Challenge: Destroy all the tomb's Arrow Traps (24-26/35)
After that another set of three arrow traps comes up on the right.

In the next part you have to get past some columns with shooting skeletons on top. After those you will come up to a square with an Osiris glyph.

Upgrade:
Stand on the glyph and raise it quickly. From there jump across the tops of the moving spiky columns. There are five of those and on top of the last one is the Max Ammo Upgrade.

Next you need to jump over a moving spike roll, run past a set of columns with shooting skeletons on top and jump another set of two moving spike rolls.

Challenge: Destroy all the tomb's Arrow Traps (27-29/35)
Now head over to the right side because the next set of three arrow shooters is coming up. Once again use a bomb (or if you prefer any other suitable weapon if in replay).

Then comes a combination of spiky columns and spike rolls.

Challenge: Destroy all the tomb's Arrow Traps (30-32/35)
Immediately after that are the next three arrow shooters on the left.

Run past more spike rolls.

Challenge: Destroy all the tomb's Arrow Traps (33-35/35)
The next three arrow shooters are back on the right.

Continue along the crumbling walkway. At the end have your Egyptian raise the shield and have the grapple character climb up and use the grapple to pull the other one up. This is where the level ends. You will be transported to the hub level.
