Players of Tomb Raider 3 will recognise Sophia Leigh from the earlier game. It seems that Lara's best endeavours in London didn't quite rid the world of Sophia for good and now she's returned to take her revenge...

Squished! Lara has only a second or two to react to the sound of a huge meteorite rolling towards her. The correct reaction is to sideflip to the left or right and let the massive rock fall into the pit. After that bit of excitement, take a walk around the central pool and note the windows in the rock wall on one side. A quick peek through these will show you at least one big guy with a hole in his chest (there's actually two).

If you stare at them too long they'll come outside and start beating Lara up, so don't hang around since we'll be back here soon enough. On two other side of the central pool are long, high passageways leading to the outside. One of them has another huge meteorite suspended at the end. Approach this passageway with care and note the translucent walkway leading along it. Step onto the walkway to trigger the meteorite and immediately backflip and sideflip out of it's way.

Follow the walkway to the end, picking up 3 pairs of grenades as you go and then return to the central pool. Go around the pool to the other side and follow the translucent walkway down this passageway to retrieve a rocket and more grenades. Again return to the central pool. Climb up through the opening in the cave wall opposte the windows and go around the pillar here to pick up some flares. Take care not to fall in the toxic gloop and return to the central pool.

Climb into the doorway between the barred windows and head up the stairs to where they widen out. You'll now have to take care of those two big guys you saw earlier. When they're both dead (again!), return to the bottom of the stairs and pick up some flares and some MP5 clips on the bottom step. Walk back up the stairs and enter the first doorway on the right. Hop down to a lower level and enter the room on the right with the barred window.

Take care to avoid the sparkly areas of floor and collect a small medikit. Climb out back to the stairs. Go across to the opening on the opposite side and drop down to the second room with a barred window. There is more sparkly gloop here but you can walk around the edge and pick up the small medikit in safety. Exit the room and climb the twisting steps on the left. These actually take you to the same place as the central staircase - a deep pool with several corpses dangling from the ceiling and a swinging burner off in the distance.

Pick up a rocket behind the pillar on the right side of the main staircase and then walk along the edge of the deep pool, lighting flares to locate the series of small, translucent platforms that will enable Lara to cross it. Take a standing jump from the ledge to the first of these platforms and then hop from one to another until Lara is one hop from the far side of the pool.

The ledge on the other side of the pool has a short slope on the other side. Be sure to angle the final jump so that Lara doesn't slide into the path of the swinging burner. Pick up some more flares at the right hand end of the ledge. After getting the flares, go to the left hand end of the ledge and position Lara at the middle of the ledge facing the small, square ledge ahead. Take a standing jump to that ledge, timing the jump to avoid the swinging burner.

When Lara lands on the ledge, you get a wide angle view from the opposite side of the cavern ahead, showing Sophia Leigh running into view and climbing up a large block. Get control of Lara and take a jump across the gap ahead. Sophia may be firing at you now, but ignore her and run around the corner to the right. Climb onto the low step with the small medikit and then jump to the grated ledge on the left (below the dangling mutant) and climb to the next ledge for another small medikit.

Return back to the grating and jump diagonally back to the ledge you were on earlier. Take a running jump across the wide gap towards the area where Sophia is standing. Grab the large medikit near where you land and then run forward and drop into the lower area on the left - it's safe here and there's a hiding place in the far left corner. Roll when you get there as you'll have attracted the attention of one of Sophia's heartless goons and you'll need to take him out.

Sophia fires around 10 energey bolts and then pauses to recharge her energy (you hear the recharge - she also pauses to cackle wildly, but don't confuse the two!). During one of her recharges, climb out of the low section and take a running jump back across the pit to the other side. Climb up onto the low ledge and jump from there to the grating and up to the higher ledge. Go around the square pillar to another safe place.

When you're ready to move, climb onto the low ledge to the right of the sqauare pillar. Walk to the far side and jump/grab and haul up onto the higher ledge. A meteorite drops out of the sky harmlessly at this point and Sophia stops shooting at you and starts climbing to a higher vantage point. This gives you time to explore.

Climb onto the low flagstone walkway to the left and run around it into the cave in the far left corner of the cavern. There's a large medikit in here, guarded by another of Sophia's heartless brutes. Exit the cave and run across to the far side of the flagstone covered area, taking care to hug the cave wall with your left shoulder. There's a set of wide steps on the far side but as you get near them, you'll probably be distracted by a flickering flame between two square columns.

Go round the right hand side of the closest pillar and up onto the altar area inside the colonnade. Shoot the heartless guy who approaches you and watch out for the relatively harmless falling meteorite. When the meteorite has gone, go to the bottom of the wide steps and pick up a large medikit. At the top of these steps, throw the switch to open the nearby doors.

Once through the doors, Lara is immediately jumped by four of the heartless guys. Three come from in front and one from behind. They're very quick but the Desert Eagle make short work of them. When the dust has settled, pick up a small medikit near one of the bodies and another small medikit and some flares at the back of the room under a barred window. Go through the doorway on the left just beyond the corpse with the red light shining out of it's forehead and go around to the left.

Slip past the swinging burner and use the switch to the left of the stairs to open a trapdoor above. Climb up the ladder to the fresh air and to meet up with Sophia again. You enter this area on a ledge: run forward and drop off this to a much lower area and run forward onto a grating covered section. Pick up the rocket at the far end of this area and get ready for the final confrontation!

when you're ready to go, climb onto the wall overlooking the area that Sophia is standing on. There's a huge pool of radioactive gloop far below and a large medikit on a block to Lara's left. Climb onto the block to retrieve the medikit. You need to do this to force Sophia to move into the position from which she can be killed and also to release another meteorite that falls harmlessly into the pool below.

Jump back down to the low wall and then to the grating covered area. Duck behind the pillar, where it's safe, and catch your breath. Head over to the low step near where you picked up the last rocket. Lara is safe here even when she's able to see Sophia. Take out the rocket launcher and count out Sophia's energy blasts. When she stops firing and starts recharging, let her have a rocket.

You need to get the timing right, but when you hit her dead on as she's just starting to recharge, you'll notice static energy swirl around Lara. Then Sophia will let out a groan and fall down. Now go to the far end of the low wall and climb onto it. Jump down onto the low stone wall at the end of the pool. Turn around and take a running jump oto the ledge nearby to pick up two rockets.

Return to the low stone wall and run to the far end of it. Climb up into the structure above and ransack the room beyond and the one to the right. Then cross the back of the building to the small room on the far side and drop onto the second low stone wall that cuts across the pool. At the far end of this is another ledge containing 2 more rockets. Pick them up, return to the low wall and cross back to the building at the end.

Jump from the end of the stone wall to the long room below Sophia's final position. Climb up to where she was standing and pick up the Hand of Rathmore again. When you do, a small door opens in the back wall of the room below. Drop down to floor level and go through this door to a ramp. Slide down the ramp into a pool and climb out of that to make your way towards the beach. As you do, a hot air balloon begins to drop down.
