Lara Croft and the Temple of Osiris/Walkthrough/Chapter 1

Chapter 1: The Pyramid of Osiris
This is the first chapter of the game, where you will start learning all gameplay essentials. Once you are revealed the background of your story, you will start your adventure. Start moving Lara around to get to know about her actions, movements and others, and once you feel confident by only moving around and not prompting any special interactions, go ahead and start playing more ambitiously.

To do so, first cross the bridge and turn on both brasiers by lighting up your own hand torch. Once you do so, a new bridge formed by two pillars will raise. Go up these pillars and you will see a tip message telling you about using your gun to burst jars to get all treasures hidden in the map. Now that you know about that, go down the pillars again and start looking for various jars. Break them with your guns and recover the diamonds from within.

Secret: At the end of the zone on the right side of the area where the pillars stand, there is a small hidden area if you jump down to the botton right corner of your screen (you will see some shiny spots to guide your jump).

Once you've finished smashing the vases, use the Staff of Osiris to destroy Set's Mark and to remove the forcefield blocking the passage to continue. You'll reach an area with a huge mechanical eye that will rise out of the spike pit in the middle of the room, launching damaging fireballs to you. This is the first enemy of the game that will inflict damage to you, so be careful and learn about the mechanics to move and dodge. There is a small perdiod between fireballs in which the eye is vulnerable, so use that time wisely and shoot the eye with your weapons to get it out of the way. Once you destroy it once, it will rotate the direction it faces onto, and a gate in that direction will open. You'll need to destroy the eye once again following the same process. This occurs up to 4 times, with the eye lookin in all cardinal directions, so repeat the methodology until the eye is destroyed. YOu should break the vases you encounter in the corridor of each cardinal point to gather diamonds as the eye rotates, since the previous sections will be closed once you beat the eye facing in a certain direction; however, once you beat the eye completely, all sections will be open again, and you can reclaim whatever you left behind. In co-op mode, each player must stand on a pressure pad and wait for the eye to focus on them before blasting it. Otherwise the trap mechanics are about the same.

After the cutscene revealing the intentions of Seth to revive his army, various skeletons will animate and attack you. Attack them with whatever you've got at hand (although the staff of Osiris is much better for constant damage output). SECRET: Before raising your staff to continue, shoot the orb that you will see floating in the top left corner over the void. That will open the forcefield that was right behind the point where the skeletons raised, revealing a secret area where you can collect a red skull. Once you gather it, go to the square with the glowing green markings in the right corner, and follow the instructions to raise the staff and activate Osiris's glyphs. After doing this, a pillar will raise beneath you, letting you continue by jumping to the ledge ahead.

In the next room, fight some more skeletons and break the vases you find on the way. There is also a stone sarcophagus in the lower corner of this area, which you can open with a remote bomb. After the detonation, you will need to destroy another skeleton raising from the generated rubble. By doing so, you will complete the challenge "Free a Skeleton from its Sarcophagus", earning a Max Health Upgrade. There is a chance that no skeleton will appear here; if that happens, you must proceed further and find another sarcophagus to repeat the process.
