The temple begins in a hostile intersection. Draw your weapon and look to the right. Blast the tribesmen in the hallway and then head up there watching out for more tribesmen. If you get poisoned, quickly clean the stairs of all the enemies before having a medikit. At the top of the long staircase, crawl through to the level's big puzzle and pick up the medikit.

The line of rolling blades rakes the room from end to end. You can see a Save Crystal in the middle of the room but can't see four switches (two on the wall to the left and two on the wall to the right). Beyond the Save Crystal is the closed exit door. Guess what you have to do!

Jump from the upper ledge (sliding slows you down) as the blades roll past to the right and sprint to the Save Crystal. After grabbing it arc around to the left and run up the slope. Position Lara against the wall on the join of two floor tiles to the right of the switch and duck. That was close!

When the blades roll away, stand up and press the switch. Sideflip left twice, position yourself in safety again and duck until the blades have gone (this is being brave - you may like to duck more often!). Stand up and press the second switch, roll and head down the slope. Aim to jump the rolling blades at an axle point as they head towards you. Once you're over keep going to the other two switches and repeat the previous manouevres until all four are pressed.

When you press the last switch duck until the blades have gone and then stand up, roll and run down the slope to the exit door and safety. Some people prefer dodging the blades by standing in the corners of the room - the general principle is the same but I found ducking down to be much easier.

Slide backwards down the slope, grab the edge for safety and drop to the ground. You shouldn't be too surprised to hear the ceiling start to come down on you - and it's spiked! Roll and head for the textured block on the left. Pull it out and the spikes will come to a halt. This also happens when you throw all three switches but that's very hard work.

Throw all three switches to open the exit door (don't leap around - the spikes are still above you!). Hang and drop down the hole and slide into the big room. Have a good look around and pick up the small medikit. The first of two boulders is poised for its downhill run. When you throw the switch underneath, the area lights up, and the entry door unseals.

Start running towards the exit. The boulder releases when you reach the different coloured floor tiles and by then you should be sprinting. Sprint down the run and out the door, back into the area you saw when the level began. Make a right turn and don't stop as there's another boulder! In the passageway, make for the Save Crystal. The flooring panels on either side of the main path will collapse so keep moving. As long as you don't start sprinting too soon, you should have just enough juice to make it to safety, underneath an archway.

Don't sweat it if you miss the Save Crystal on the first pass as you can crawl back and take it from beneath the rock. As you walk into the hallway, a tribesman appears on the right, near the boss's gate. Two more enemies appear moments later on the left. Take all of them out and then go back up the long staircase, picking up the small medikit from one of the dead tribesmen

At the point where the staircase switches back, you may hear a door open high above. You can barely see it in the dark. Continue to the top of the stairs and jump from the stairs to the wall and shimmy left to the opening. Secret #1 - In the dimly lit room, collect the flares from the middle, the Desert Eagle pistols, ammo and medikit from the corners and exit.

Return to the bottom of the stairs and go down the third passage. Once you slide down the slope behind the open gate, you enter the lair of Puna. The boss sits with his back to you on a high throne. You have to approach to get his attention. Once he turns round jump backwards off the stairs and jump from side to side, keeping those guns blazing.

It's not too difficult to kill him - I did it in 25 shots with the Desert Eagles and Puna never managed to create any helpers. You may find, during the fight, that Puna fires an odd colored bolt off to one side and summons some help. Take care of the hired help before turning back to the boss. The boss won't attack you until the summoned enemy is dearly departed. Don't worry too much about getting poisoned. If Puna tags you with a lightning bolt, no amount of health will save you anyway.
