The start of the level begins peacefully enough, collect the medikit and magnum clips either side of the entrance. A couple of squares on grab the Uzi clips from the currently dormant demon guards.

The next room is one huge boulder trap. Walk to the top step. As you do two warning boulders drop and roll harmlessly across the room. Any squares with the curved symbol are safe, this includes the first two rows you are standing on. There are two more safe squares to the right, halfway down the room. From them you can jump to the alcove.

Alternatively, it is not too difficult to trigger the rock traps and jump out of the way as the boulders drop.

The two alcoves both contain switches and as you pull them the relative demon at the other end of the room activates. Once they're dead run back down the middle row of tiles and enter the newly opened passageway on the right.

Jump through the metal jaws and turn right to pick up the two magnum clips. Jump back through the jaws and run over to the other passageway. Run past the darts and jump through the deadly jaws and stop at the edge. Take a breather and save the game, the next bit is tricky.

There are a number of sloping cliffs that you must jump off. Walk to the edge and take a couple of side steps to the right. What you are going to do is jump forwards, slide down a little way and jump off this slope onto another. Slide down this slope a little more and jump again, onto yet another slope. Jump again and keep jumping between two opposite slopes, while doing this hold the right direction key.

You will slowly make your way along the two slopes and at one point Lara will land on a flat slab on the left side. Stop to get your bearings and then head over to the area on the left and get your guns out, another demon needs dispatching.

At the end of this gully, where the demon first appeared, is a medikit. Back at the start of the gully is a flat ledge you can pull yourself up onto. As you do a demon pops up from the pit in front of you and requires dispatching.

Lower yourself down into the lava pit to the ledge below. Jump across to the other ledeg and drop down. You can now see a medikit and can either slide to it or jump and grab. After picking it up make your way out of the pit.

Now turn to look at the vast lake of lava running down the right hand side of the cavern. Make a standing jump onto the curved ledge to get a better view. There is a demon in the far left corner which can be picked off from here.

Make a jump onto the square block in front of you. From here you should be able to see two Uzi clips. Jump over to get the first and then make a series of standing jumps to get the other. Jump onto the square block with the symbol on it. This opens a door at the end of the room.

You have only a limited time to do a running jump off this block to the ledge at the side of the room, leg it to an outcrop opposite where the door is and finish with a jump, grab and sprint through the closing door. Go for it!

Do not worry about the demon pod just yet. Lower yourself down to the floor and follow the path around. Climb up to the top and turn around. You need to make a tricky jump onto the middle of the pulsating wall to your right. As you do the two demon pods will be triggered so get ready to unleash your firepower.

Stand with your back to the wall and use the look key to line yourself up, then do the run and jump. You may find pressing the right key mid-air will help. The two flying demons that now appear are unworthy adversaries, send their burning corpses to the ground. Another tricky jump is coming up. There is a fairly large exit to the room in the right wall. You need to do a running jump past the cream column on the right, and grab hold of the level part of the path that is sticking out. The angled part will not do, as you will just plummet to your death.

Once you have pulled yourself up you will see a centaur at the top of some stairs. It will not attack and you cannot shoot it, till you walk off the top step. So climb up the stairs and get your guns ready. When it does attack just keep jumping side to side whilst firing, it dies fairly quickly. Lower yourself down the hole to collect an Uzi clip, and head off down the steep slope into a large water filled cavern.

As you drop in try and spot the water level ledge on the right. There is medikit under this and you can climb out of the water onto it. Get your guns out and side-step a couple of times to the right. A demon is patrolling above, take care of it from where you are before climbing up. Grab the magnum clips and make your way to the end of the island. You should see a grotto slightly to the left inhabited by three demons that cannot harm you at the moment. Do a running jump and grab onto the far ledge that runs around to the grotto.

Walk onto the slightly higher brown block and take your time picking off the demons. Go in and climb to the back of the grotto, below are lots and lots of Uzi clips. As you climb back out from the end two new demons are waiting for you. On the right hand side to the mouth of the grotto is another brown block, climb onto this to collect a magnum clip and to get a clear shot at another demon on the other side of the cavern. Go back around and jump across to the starting island, head over to the cream coloured structure. Climb up it and collect the Uzi clip at the top. Scramble around this island on a ledge and climb down to the water's edge, you should be able to see a small ledge at water level opposite.

Do a running jump over to it and get ready to pull your shooters out. A demon is patrolling this corner of the cavern. Once you have taken care of it, jump onto the block slightly to your right and head over to the corner. Collect the Uzi clips in the two alcoves and then pull the two switches that open up a new exit. Before entering you may want to take a swim around the cavern and pick up a couple of medikits. Then enter the set of doors when you you have finished. This leads you into an arena style room wiih large archways overhead, as you walk down two nasty centaurs will attack.

The best thing is to run straight across the room and around the pillar at the other side. This helps split the two centaurs up. Use the column for cover and jump in and out picking the two centaurs off one at a time. Once you have dealt with them collect the Uzi clips from the middle section of the room and grab the two medikits from the end two corners.

Now for the switches, pull the two nearest the glass end of the room and then pull just one of the other two. They both open one of the doors to the end room. There is a reception committee waiting for you in the end room so have your guns ready. When it is safe enter the room and have a look around before walking anywhere.

If you run into the room, about halfway across the pods burst giving you two flying demons and a centaur to deal with. Your best bet is to back into the room and when the pods burst leg it out and take care of the beasts from the doorway.

Once you have, dive into the pool and pull both the levers at the bottom. Collect the goodies from the left side of the room. Grab a breather and head into the other doorway, there is loads of stuff to collect, so take a few breathers if you want to get everything.

An underwater switch opens the locked doorway that is to its left. Swim out to emerge back in the main water filled cavern. Swim straight-ahead and slightly round to the left. Climb up onto the central island and climb up the blocks to the top level. Run around the edge to enter the central structure, climb up the block you come to and again climb up to the left. Follow the path and enter one of the two open doors you come to, a demon prowls within so take care of it.

Head off down the black corridor picking up the shells as you go. At the end a door automatically opens for you. In this new room eight demons stand inactive, waiting for something to happen. Collect all the shells, saving the middle four till last.

Once you're stood on the middle section you're trapped. If you try to make a run for it you activate all eight demons at once, which is a bit of a handful even for a girl of Lara's abilities.

Carefully walk off the slab and walk straight ahead. As you reach the black area the first demon next to the door springs to life. Use the slab to make your stand, and take the demon out. Do the same again in a different direction and this should activate the other demon by the door. The remaining demons activate in pairs, as you get closer and closer to the door. Slowly back up until you see or hear them moving and leg it back to the slab. Once you have taken care of the final one leave the room and go in the other now open door.

Enter the next room that is lined with inactive pods, pull both the switches and make a dash for the door. Say hello to Mr Centaur and introduce him to Mr & Mrs Uzi 9 millimetre. The pods in here are, again, empty but do explode. Get to the end of the room and head down the ramp, more clips and health can be found in an alcove on the left side of the slope.

This final room has active pods with flying demons. If you are careful they will not explode so can be ignored. The switch opens the final door. Pull it once but do not go anywhere. The cut scene wastes valuable seconds and the timing is tight. When it resets pull it again and run for the door. Some pods may explode but ignore them and concentrate on that door. Dart through it and slide down the slope with pods bursting around your ears and swim off to your right.

Congratulations! You've taken care of that Unfinished Business.
