You enter down a short hall that has four pictures. Above each picture is a symbol and below each picture is an open area. You need to find the four crystals to place in the correct slots. When you first enter the large circular room, you will see a knight to your right. It takes about 5 shotgun shots to kill him. Do not shoot him while he has his shield up. You can run behind him and shoot him from behind. He regenerates so try to do as much as you can while he is “dead" or simply run around to avoid him. The circle floor has four quarter circles in the middle. Each one of the quarters will lead you to a different challenge. By stepping on one of the quarters, three doors will open. Each door has a lever at the end of the hall. Pull the wrong lever and you will be dropped into the Firey Doom (TM LaraCroft709). If this happens, you need to find the room with the dumbwaiter and pull yourself up to the main level. The walkthrough will tell you at the beginning of each challenge which lever to pull.
After you have gotten all the crystals, step on any one of the quarters and run to one of the doors that will allow you to pull the lever and drop a level below. We chose step on the water symbol and drop down. Slide down into the firey doom (TM LaraCroft 709). There is a large medback at the base. Go out and turn left. Crawl under the rolling spike. Jump across and stop.
Time your run under the big crushing rock. We used a run and jump move. Be careful to run just far enough or you will get sliced by the knives/hooks. Start running forward when the knives are right in front of you. There are little knives that open up like flowers right past the knives/ hooks. You should be able to run by those. There are more knives that come out of the walls. Walk next to the wall right to the knife and wait for it to fall and then walk past it. Past those knives is a small door with dumbwaiter. Remember this as it will take you to the top floor. There is a horizontal/vertical spinning machete. Walk up to it and wait for it to be horizontal and walk underneath it. Go forward and jump across the chasm.
Walk slowly. Metal spikes will appear. Walk, zigzagging, to avoid being struck. Continue to walk and jump across a chasm. Continue to walk forward and jump across another chasm. Be careful because the tracks on the cement are for a rolling spike. Jump across another chasm. There is a door to the right. Enter and go down the stairs.
Pull the lever. Walk into the circular room. Turn to the right. There is a symbol of the wind. Turn the valve. Walk to the end of the platform where the ladder is. Take a running jump to the platform opposite you. Take the ladder that goes up. This will take you to the symbol that represents the Wrath of the Beast. Turn the valve.
Return down the ladder. Jump back across to the platform that you were on originally. Jump forward to the top part of the middle unit. Find the zip line and pull yourself across. Go left and up a ladder to the valve for the water symbol. Return on the zip line to the center unit. Hang off the ledge above the area that has a ladder and drop and grab the ladder below. Pull up and walk around to the rear of the unit by the symbol. Turn the valve. The furnace is now heated. The poles around the unit have swinging blades. Go to the right. Walk up to the blades and wait until the bottom blade swings right by you. Get to the ladder that goes down. (You actually have enough time to run around the circular opening and avoid the spinning blades altogether. You may lose a little bit of life, but not much).
There are swinging blades and rotating spikes. You need to jump over the spikes and run by the blades to the right. Keep going around and you should see a ladder that goes up. Take the ladder up and walk across the platform. Take the next ladder up. You should be a the platform you were on when you first entered the room. Go up the stairs, press the lever and wait for the door to raise. Go back up to the circle of fire.
You can go either way back to the room with the dumbwaiter. Each way has its own perils. I think the way to the left is easier. The dumbwaiter room is the one right past the horizontal/vertical spinning machete. Pull up one time and get health and shotgun shells. Return to the dumbwaiter and pull on the chain again to return to the main level. Exit and enter the circular room. Four of the sections are now pillars that raise and lower. Look for the lowest one. It is the one closest to the pile of rubble. Jump on it. Turn to the right and jump on the next one. Turn again to your right and jump. You should now be on the last and tallest pillar. Face the center circular support, grab it. Walk around until you see the flat horizontal pillar.
This was a very buggy part of the game. Lara ran around in slow motion and the loading caused the game to freeze. We could not reload the saved game at the 3d level and had to return to repeat some of our actions to get up to this spot again. My suggestion is to save often and at different spots even though you may not be in any danger because of the bugs. Cross to the second level. Knights will break out of the wall. Continue around the room to the right until you get to the stairs. Go up the stairs. At the top of the stairs is another knight.
At the top of the stairs turn right and walk to the end. Back up (be careful not to fall off). Run and jump toward the opening in the wall to the right. Grab the ledge and pull up. There is a lever there. Pull the lever. Face the wall. Alternatively, you can run around the balcony, all the way to the left. At the end of the balcony, there is a wall to the left in the dark. You can climb up and to the right to get to the ledge with the lever. Climb back down and run back to the alcove where you originally entered the 3d floor. The door at the rear of the alcove is now open.
Go through and pick up the ammo and push the wall. You will gain an upgrade in strength and a big med pack. Shoot the Knight that comes down the hall. Go back to the ledge with the lever. You should have enough strength to climb up the wall and to your right and then to your left where there is a small green stone platform.
Gather your strength. Turn Lara so that she is facing parallel to the ledge where the lever is. You want to climb the ceiling forward and to the left. At the end of the ceiling area, Lara will climb upward until you get to a small ledge to the left and a room. You must position Lara correctly or you will not have enough strength to make it to the top. Go through the door and enter the door the left. Go up the stairs. There is a cut scene. Inside this room are hooded figures. One of the figures is holding a blue light. The light switches from statue to statue. You are trying to go to the blue light. To do this, you must shoot the Spirit Boss until he is stationary. Once he is stationary, holster your weapon and run to the blue light. Our best results occurred when we stood in one place and shoot the Spirit Boss until the light eventually came to the statue closest to us. You are actually going to be grabbing one of the Obscura Paintings. Once you have the painting, run out the door where you first entered. This is the end of the Hall of Seasons level.
Note: there is ammo in the perimeter of the room with the Spirit Boss.
