Cave

Pick up the flares on the right as well as the ones on the left. Follow the guide down into the cave. In the first pit, you will find a Shotgun. Pick it up. Get further down into the cave. Turn left. On the left wall you will find a ramp. Pull yourself up and run up the slope. Collect the red shotgun ammo and return to the ground. Shoot the scorpion in the next pit and collect the large medipack. Get further down. f Get further down into the cave. Shoot the dog you encounter. (If you've collected the secret, you might avoid the dog.) Run up the ramp to get the large medipack. Drop down to the right and collect the small medipack in the dark corner next to the entrance. Now enter the passage.

Sandpit/1st Half of Artefact

Shoot the two scorpions. Then grab into the hole on the right wall to find a large medipack. Grab into the hole opposite on the left wall to fill the sandpit with more sand. Now run back down to that chamber and cross the sand. Collect the first half of the eye, this will also open the door upstairs. Then pick up the small medipack. Run back up.

2nd Half of Artefact

Run into the next chamber. Run down the stairs behind the pedestal. You'll come to a room. Wait behind the guide till he has triggered the trap. Now run up the stairs. Pick up the artefact part from the pedestal.

Eye of Horus

Combine it with the other part to get the Eye of Horus. Run down the stairs and get back out. Run up the stairs on the left. Run to the big gate on the left and use the artefact to open it. Shoot the two dogs. (The guide will help you by burning them with his torch if he can.) Run up the ramp. Follow the passage to a huge chamber with a sphinx. Drop into the trench on the right to collect some Uzi Ammo. Now drop into the left trench to find a small medipack. (At this point, you can already collect Secret 12 and 13, but I'll explain that later. Scroll down if you want to read that now.)

Opening the door for the Guide

Follow the stairs to the left. Enter the passage. As soon as you enter, the guide will set the liquid in the trenches on fire. This will open the door. Follow him through. At the crossing, turn right. (If you follow the guide, you will come to a locked door.) Collect the small medipack in the pit. Climb out on the other side. You'll come to a room with a statue. This room is also filled with oil. (Behind the gate on the left, the guide is waiting.) Run into the passage on the right. Run up to the top and pull the rope. This will open the passage and the guide will set the room with the statue on fire.

Fire Riddle

Now you have to solve a little riddle. You have to jump exactly onto the lit spots. If you've done it correctly, the torches on the front wall will be lit. If you make a mistake, all of them will go out. Jump onto the square ahead, then the one on the right, the next one ahead, make a side sault to the left then jump onto the last square on the right. (As long as you hit all of them correctly and don't touch any other square, that includes the borders, you should be alright. If you've made a mistake, you have to go back into the passage. Slide down to the right. Follow the passage. In the chamber you'll also find a shotgun with some ammo. Pull the rope to reset the puzzle. Run up the other passage to get back to the puzzle.) If you've made it, the gate will open. Step through and collect the timeless sands. Leave the room on the other side.

Sphinx Chamber

You'll end up in the chamber with the sphinx again. Now run down into the passage you'll find on the left side of the sphinx. There you'll meet the guide again. He will open the door for you. (The guide will now look very terrified and run away.) Enter the passage and shoot the three scorpions. Drop down into the pit. Collect the red shotgun ammo in the middle of the room. Climb up on the other side. Use the timeless sand with the statue. The room will now be filled with sand. The chamber with the sphinx will be drained. Return to the other side. Shoot another scorpion. Return to the chamber with the sphinx. Crawl into the sphinx' head. (Keep in mind: You have to press the crouch button.) Slide down the passage.
