(ABOUT THE PC DEMO: The playable demo includes the first half of this level.  Everything should be the same as the level in the full game, except the demo ends after the cut scene in the middle.)

OPEN AREA WITH WATERFALL AND HUGE MACHINE: When you drop down from the low stone platform near the entrance, 2 wolves emerge from the area to the right of the platform (left when facing it).  There's plenty of open space to move around as you fight, but you can also climb up on the rocks to the left of the pool and shoot the wolves from there.  Here you'll also pick up the FIRST COG, one of three you'll need to repair the huge wooden machine on the cave wall.  You could climb up and replace the first cog now, but it's not necessary yet.  Wait until you get the second.

For now, jump in the pool, turn to face the low platform where you entered the area and then swim down through an underwater tunnel.  Surface in the small cave at the end of the tunnel and pick up a small medipak.  (NOTE: When you enter the little cave, the secret chime sounds, but this is not a secret.) Swim back to the pool and climb out.

Now climb the rocks behind where you found the cog.  Jump to grab the stone handhold next to the waterfall.  Jump up to grab the handhold above.  Climb around to the left, pull up and vault onto the ledge ahead and pick up some shotgun ammo.  Grab the narrow ledge and climb as far as possible to the right then jump and grab the next handhold.  Climb all the way around toward the falls, jump up, then pull up onto a ledge.  Climb up straight ahead onto a wider ledge with steps leading up to the right.

ABOVE THE FALLS: Turn right, go up the steps and follow the short tunnel forward and around to the right.  You emerge near the rapidly flowing stream at CHECKPOINT 2.  Take a running jump across the stream to grab the ledge on the other side.  Pull up.  Climb up on the right and jump back to grab the wooden ledge behind.  Again pull up.

Follow the on-screen instructions to target the ropes holding the wooden platform above the stream.  (If you're using Advanced Hold or Advanced Toggle combat mode, Lara should target it automatically when you shoot in its general direction.  Otherwise, hold the Target Lock button to lock on, then shoot.) Shooting the ropes drops the rickety wooden platform into the water, leaving a horizontal bar.  Grab onto the light stone ledge, climb around to the left and jump back to grab the bar.  Swing around and jump to grab the next ledge.  Pull up and follow the tunnel around to the right.  Grapple-swing across the gap to the wooden platform ahead.

Go around the wall on the right, climb up three times, climb around to the right and then jump to grab the stone handhold on the other side of the wooden platform.  Pull up and follow the tunnel around to the right.  Cross the wooden bridge and pick up the SECOND COG.  Taking it triggers CHECKPOINT 3, as well as the appearance of 2 bats, which approach from near the wide waterfall near the wooden bridge.

If you didn't already do so accidentally while firing at the bats, shoot the ropes supporting the bridge.  This leaves a metal ring perfect for grapple swinging, but don't do that.  Instead go to the left side of the ledge, wait for the horizontal bar on the turning wheel to move toward you and then jump to grab it.  Swing around and, when the wheel turns so Lara is nearest wood-and-rock structure in the middle of the waterfall ahead, jump to grab it.  Climb around to the right and up to the highest rock handhold.  Then jump back to grab the ledge behind.  Follow the tunnel to a switch and use it to open a barred opening underwater somewhere.  CHECKPOINT 4 registers here.

Return to the higher tunnel opening, drop and hang from the edge, climb to the right and then drop to grab the handhold below.  Climb to the right and jump to grab the handhold on the other side of the wooden platform.  (You did this earlier on the way to the wooden bridge.) Pull up and follow the tunnel to the opening where the bridge was.  Ignore the metal ring and drop to grab the broken bridge hanging below the opening.  Climb down until Lara is level with the small opening on the right.  Jump to grab it and climb inside.  Follow the tunnel to where it opens out.  On the ground you'll find a large medipak and the SHOTGUN.  (Whoo hoo!) Drop into the water and float downstream and over the falls—Lara does a sweet, spontaneous cannonball—into the pool near the start.

NOTE: If you didn't get the small medipak in the underwater passage earlier, do that now.  (Refer to the start of the walkthrough for info.)

OPEN AREA WITH WATERFALL AND HUGE MACHINE (again): When you climb out, 3 more wolves attack.  If you want, you can climb up on the rocks to the right, above where you found the first cog, and shoot them from above.

Now climb the wooden ladder to the first level of the big machine.  Place the FIRST COG on the shaft and use the nearby switch to activate the first stage of the device and trigger CHECKPOINT 5.

Stand beneath the small turning wheel and jump straight up to grab the horizontal bar on the wheel when it comes within reach.  Swing around and, when one of the horizontal bars on the big wheel comes within reach, jump to grab it.  When the big wheel approaches the ladder ahead, swing around and jump to grab it.  Climb up to the second platform and place the SECOND COG on its shaft and use the switch to activate the second part of the machine and trigger CHECKPOINT 6.

Grab the narrow ledge to the right of the switch and climb to the right.  Jump across the gap to grab on again where the ledge continues.  Climb around the corner and on to the right.  Jump up to the handhold above, then back to grab the wooden platform behind.  Pull up.

You're still missing the THIRD COG, so don't bother climbing over to the third switch yet.  Instead, turn around and locate the little stone building set into the valley wall below a big wooden structure.  (There's a dangling rope above and to the right of it.) Take a running jump from the point of the ledge to grab the narrow stone ledge on the front of this little building.  Climb around the corner and continue to the right as far as Lara will go.  There's another ledge above and the dangling rope is above and behind now.

If you don't mind missing a pick-up, you can jump up to the higher handhold and then to the dangling rope (and skip down to the next paragraph).  But if you want every item, instead drop down and grab the edge of the small opening below.  (If Lara starts to lose her grip, press Interact to do a saving grab.) Climb to the right, pull up into the opening and slide into the room below.  Climb onto the wooden platform and take the large medipak.  Slide down the ramp to emerge on the ground near the pool.  Repeat the climb up the ladder and moving bars to the wooden platform above the one where you placed the SECOND COG.  Repeat the jump from the point of the platform to grab the narrow ledge below the dangling rope.  Again climb all the way to the right, but this time jump up to grab the handhold above.  From there, jump back to grab the dangling rope.

While hanging onto the rope, turn right so Lara's back is toward the spot where you placed the SECOND COG.  Climb down the rope to the bottom.  Then swing, jump and grab the narrow ledge on the wall ahead.  Climb all the way around to the right, jump to grab the wooden lintel above the doorway and drop down.  Lara's weight shakes the wooden platform, causing the ladder to fall down and break away, leaving only a horizontal bar.  Ignore that for now unless, for some reason you need to get back to the area above the falls.

CAVES LEADING TO THE VALLEY: Go forward, climb over the boulder that's partially blocking the tunnel and continue past CHECKPOINT 7 to a low overhang.  Duck or roll under it and draw weapons—the shotgun is nice here—to kill the bear that charges at you.  If you want conserve shells, you can also roll back under the overhang and shoot the bear from safety.  It won't come through the low opening.  You can also climb onto the structure on the left side of the cave.  The bear also can't reach Lara there, but after taking a few hits, it will hide and you'll have to draw it out again by dropping down.

ARTIFACT #1: On the right side of the cave is a raised opening containing an artifact.  You can't reach the edge from below, so climb to the top of the wood and stone structure.  Pick up the 50 caliber pistol ammo.  Then turn left (so the cave opening where you entered is behind Lara and the wooden ramp is on her right) and walk to the edge of the wooden platform.

Now you need to position Lara carefully so she'll be able to make the next jump.  She should be standing at the edge of the wooden ledge just above the stone handhold on the structure below.  Shift the camera in front of her and point it downward to see if she's lined up with that handhold.  Now jump down onto the sloping wooden roof and, just as Lara starts to slide, immediately jump again to grab the stone handhold near the corner of the structure.  Climb around the corner to the left and jump back to grab the opening behind.  Pull up and get ARTIFACT #1.  Notice the medipak behind the wooden beams.  You can't get it from this side, but you'll have another chance soon.  So drop down to the ground and climb back up the wood and stone structure.

DEEPER INTO THE CAVES: Turn around to face the two vertical poles and take a running jump to grab the stone ledge to the left of the poles.  Climb around to the right, jump up to grab the higher handhold and then jump back to perch on top of the first pole.  Jump to the second, then to the doorway ahead.  Slide down the slope into another cave and go forward.

Ahead, you'll see stone steps with some ammo.  Before heading that way, take a brief detour to pick up the medipak you saw near the artifact: Go to the right to the two vertical poles, one tall, one short.  Climb up the taller pole, jump onto the slope and quickly jump again to perch on the shorter pole.  From there, jump into the opening.  (Or climb the short pole, jump to the slope, jump back to perch on the pole and then jump to the opening.) Step out onto the wooden walkway and look to the left.  There's a hole with wooden handholds on the back wall.  jump to grab one of the handholds, climb down, pick up the small medipak and climb back up the same way.  Go to the right and drop down near the vertical poles.

Continue to the right toward the stone steps, crossing CHECKPOINT 8.  Climb up and take the shotgun ammo.

NOTE: If you already have 40 shells, Lara won't be able to carry any more.  However, if you have between 33 and 40 shells, you can shoot a few to get down to 32.  Then, when Lara reloads, you'll be able to pick up the new shells to top off your supply.  You'll also have another chance to get these on the return trip.

From the ledge where you got the shotgun ammo near CHECKPOINT 8, take a running jump onto the wooden slope that angles down to the left.  Slide and quickly jump to grab the handhold on the wall ahead.  Climb to the right and jump to grab the wooden platform.  Pull up and get another box of shotgun ammo.  (Again, if you already have 40 shells, you can get this one on the way back.) Take a running jump to grab the horizontal pole, swing, jump and grab the lower handhold on the wall ahead.  Jump up, climb around to the left and pull up near CHECKPOINT 9.

Turn right onto the wooden part of the ledge and jump to grab the handhold ahead.  Climb to the left then jump backward across the deep pit to grab the opposite wall.  Climb to the right.  (This is a good place to tap Interact repeatedly to climb faster.) Drop down near the large medipak and quickly draw guns to shoot 2 bats that fly in from the area from which you came.

Before going on, turn to face out over the pit.  On the opposite wall, you'll see some stone handholds.  Take a running jump to grab the upper handhold.  The one below is broken off on the left side, so climb to the right and then drop down twice.  Climb back to the left.  It's hard to see it but if you press the Down key to make Lara lean away from the wall, you can just glimpse an opening on the wall behind her.  Jump back to grab the edge.  Climb in and follow the tunnel to the end where you'll find another large medipak.  Return to the opening, take a running jump across the pit to grab the lowest handhold.  Climb to the right, then up twice, then to the left.  From the left end of the highest handhold, you can jump back to grab another handhold above and to the right of the tunnel opening.  Jump up to grab the ledge and pull up.

Now cross over the wooden part of the ledge and climb into the raised opening.  Follow the mossy tunnel to CHECKPOINT 10.  Just beyond the checkpoint is a wooden platform, which collapses as soon as Lara steps on it.  There's no way to avoid this.  Just slide down into the lower tunnel and continue forward to CHECKPOINT 11.

GREEN VALLEY WITH WATERFALLS & WOODEN BRIDGES: There are a few pick-ups to be had in this area, but as soon as you step into the open, 3 velociraptors charge from ahead on the left.  So you'll probably want to deal with them first.  If you prefer not to run out and go head to head, there are small boulders on both the right and left sides of the tunnel opening that Lara can climb on.  The one on the left is completely safe, as far as I know.  The one on the right is just beyond the 50 caliber ammo.  Most of the time the raptors will be unable to reach her if she's standing there, but sometimes one of them will climb up and bite her.  I found if you jump up there immediately before the raptors approach, they'll be less likely to attack Lara there.  You can take a chance or just run out into the open and concentrate on dodging and shooting as well as you can.

When the raptors are dead, pick up the ammo and the small medipak beneath the small waterfall near the boulder on the right.  But stay alert, since venturing out into the valley attracts the attention of 4 more raptors.  These dinos approach from the far end of the valley.

If you're fast enough, you may be able to retrieve another large medipak, located behind the big manmade stone columns on the left side of the valley where the first raptors emerged.  There's also another small medipak concealed between the twin waterfalls.  You probably won't have time to get it before the raptors attack, but if you kill three of them, you may be able to outrun the fourth and retrieve the remaining health pack.  Just take care not to lose more heath than you gain from the pack.  When you've killed those four dinosaurs, CHECKPOINT 12 registers and a cut scene starts.  (NOTE: Don't worry if you don't get all the items now.  You'll have another chance later in the level.)

Interactive cut scene: As Lara surveys the valley before her, a single velociraptor emerges from the undergrowth, followed by the rest of its pack.  They seem more intent on fleeing something behind them than on attacking her.  The reason for their panic soon becomes clear: A massive Tyrannosaurus rex thunders into view.  It grabs one raptor in its massive jaws and flings it against the ruins before continuing the chase.  (NOTE: The PC demo ends here.)

As the action unfolds, you must press the keys that correspond to the icons that appear on screen.  When you press the correct key, a chime sounds and Lara manages to evade the danger heading her way—first the T.  rex itself, then one of the raptors, then the fallen body of the same raptor.  If you hesitate too long or press the wrong key, Lara doesn't make it.  The game reloads at the last checkpoint and you must try again.  The required controls in the PC game are Down, Up, Up.  In the PlayStation 2 game, press Circle, R1, then X.

TYRANNOSAURUS REX: You didn't think it would be that easy, did you? When the game resumes, Lara is standing in the middle of the clearing with the Tyrannosaurus practically breathing down her neck.  The chime for CHECKPOINT 13 sounds and the real fight begins.  Try to keep your distance from the big dinosaur, since not only can it bite Lara but also step on her and swat her with its tail.  You can use the shotgun or pistols.  I found the pistols much easier since Lara is more maneuverable when she's holding them.

There are a few items scattered around this area.  Ignore them for now, unless you're completely out of health packs, in which case, you can try and pick up the small medipak on the ground to the left of the temple.  Just don't hesitate too long or Lara will be lunch.

Try to keep the T.  rex in sight by shifting the camera as you circle around your target—using the left or right direction key and back key if necessary to keep moving away as you circle.  Or, back away while weaving from side to side.  This works well if you can keep enough distance between Lara and the T.  rex.  If it gets too close, roll or jump out of the way.  Then continue circling or weaving and shooting.  Keep blasting away until its rage meter (the lower of the two bars in the upper right corner of the screen) maxes out.

When that happens, the T.  rex becomes enraged, bellows loudly and then and charges.  The action shifts to slow motion and the screen blurs slightly.  Now you want to use the adrenaline dodge you learned in the previous level: Make sure you have a target lock on the enemy (right mouse button on the PC, L1 on the PS2) and plenty of room to maneuver, at least in the direction you plan to roll.  If Lara hits a wall or other obstacle before completing the move, it won't work.  To do the dodge, continue to hold the Left or Right direction key (or move the control stick in either direction) then press Duck, as though you were doing a regular evasive roll.  If your dodge is successful, you'll see two separate targeting reticules converge on the T.  rex's head.  In order to see this, you may need to move the camera to point directly at the enemy.  When the reticules meet, immediately shoot.  A brief cut scene will play, in which the T.  rex charges, hitting the nearest wall and (hopefully) losing some of its health (indicated by the upper bar at the top right).

How much damage is done each time depends on which wall the T.  rex hits.  If you can lure it into the spiky wooden barriers, that does the most damage, almost a third of the rex's health each time.  The hard stone walls of the temple do somewhat less damage, and the softer, greenery-covered areas, little or no damage.

I haven't experimented much with the different combat modes, but it may help to switch to Advanced Toggle mode for this fight.  When this mode is selected, pressing Target Lock causes Lara to draw weapons and target the nearest enemy—in this case the T.  rex.  She will keep that target locked and guns drawn until you press Target Lock again.  (You can change the combat mode in the Options menu under Controls.  Then change it back to your preferred mode after the fight.)

After the T.  rex smashes into something, it takes a moment to gather its wits.  So run away and then turn back to face it.  Lure it back across the arena and then toward one of the damaging surfaces.  Repeat the process—shoot to max out the rex's rage meter, wait for the charge, do the adrenaline dodge (Left or Right + Duck), watch the two targeting reticules converge and then shoot.  Each time the T.  rex charges and bangs its head, it will lose a bit more health until finally the last successful dodge-and-shoot maneuver triggers a second interactive cut scene (described after the alternate strategy).

ALTERNATE STRATEGY: There is a semi-safe spot where Lara can hide from the T.  rex without it attacking her.  However, it's a bit tricky to get to, and you'll probably need to lure the T.  rex away from the spot by letting it attack Lara first.  The safe spot is on top of the boulder between the two spiked logs on the right side of the open area when facing the temple.  I found that when I ran directly to the "safe" spot at the start of the fight, it turned out to be not so safe.  The rex was able to reach Lara and chomp on her.  What worked for me was to run for the spiked log to the left of the safe spot, wait for the T.  rex to charge and then dodge it.  Even if the adrenaline dodge move doesn't work, and the rex gets a bite of Lara, it is momentarily distracted and you can then jump past it and run to the safe spot, climb onto the boulder and stay near the cave wall.  With any luck, the T.  rex won't notice Lara and you can then blast away at it with pistols.  Just watch that rage meter (the lower of the two bars at the top right).  If you shoot at the rex long enough, his rage meter will max out and he may charge.  Then Lara is in trouble.  Instead shoot until the rage meter almost reaches the maximum, then stop shooting, wait for the beast to calm down, then start shooting again.  Ellymelly and ac_troll, the players who told me about this safe spot, mentioned luring the T.  rex right up to the boulder without it being able to reach Lara.  Maybe this works in the PlayStation 2 game, but it did not work in my (PC) game.  Killing the big dinosaur this way takes a while, but when you have finally whittled its health bar down to near zero, the next cut scene starts.

Second interactive cut scene: The huge beast makes one last angry charge at Lara.  Press the keys indicated on-screen to evade it.  In the PC game, the keys are Down then Up.  On the PS2, it's Circle, then R1.  When you press the correct buttons, the Tyrannosaurus smashes into the temple creating a gaping hole in the wall.  If you fail, Lara dies and the battle restarts from the last checkpoint.

THE KING IS DEAD: After the cut scene, the game saves at CHECKPOINT 14.  Pick up the small medipak on the ground near the temple if you didn't get it earlier.  There are also 2 sets of 50 caliber pistol clips—one in the bushes to the left of the spiky wooden things and one in plain sight opposite the temple.

NOTE: If for whatever reason you can't manage to beat the T.  rex and you're playing on the PC, you're welcome to download my post-battle savegame file.  Instructions are included with the download.

Climb up into the temple, cross CHECKPOINT 15 and get the THIRD COG.  Turn right, hop into the pool and swim through the underwater tunnel, first forward then to the right, to a room where you can surface and climb out of the water.  Climb up the vertical pole and jump onto the wide ledge.  Grab onto the light-colored stone handhold on the wall.  Jump up to grab the next handhold, climb to the left, then jump to grab the bottom of the small alcove.  Jump back to perch on the vertical pole.  From there jump to grab the lower handhold on the opposite wall.  Jump up to the higher handhold, then climb to the left and jump to grab the doorsill.  Pull up and cross CHECKPOINT 16.

ON TOP OF THE TEMPLE: Vault up onto the darker stone ledge on the right and cross over to the front of the temple to find another small medipak.  Return to the doorway where you climbed up from inside.  Climb the rocks to the left of the doorway onto the roof of the temple and cross over to the other side.  Take a running jump to grab the edge of the ledge beyond.

Follow the ledges along the cliff wall above the spiky wooden things, jumping the gaps as you go.  On the last ledge, jump to grab the vertical pole, climb up and jump to the ledge on the right.  Cross between the high walls and jump to grab the light stone handhold on the ivy-covered wall ahead.  Jump to the left, climb around the corner, jump to the left again.  Don't climb any farther to the left.  Just jump back to grab the wooden platform behind and pull up.

GREEN VALLEY WITH WATERFALLS & WOODEN BRIDGES (again): Now you are above the valley where you encountered the first raptors.  Follow the wooden platform around to the right, slide down the slope and jump to grab the vertical pole.  Climb to the top and jump into the jagged opening in the wall ahead.  Drop down into the room ahead and continue forward to CHECKPOINT 17.  Pick up the small medipak in the fire pit ahead.  Go through the doorway on the right and continue over the uneven floor.  Where it starts to flatten out, turn right and go through a small opening overlooking the valley.

Drop down on the right onto a wooden ledge with another small medipak.  If you want to, you can now hop down to the ground and pick up any goodies you may have missed earlier.  Otherwise, skip the next three paragraphs.

As you explore, do not drop down into the area with the dead T.  rex.  It's too high to climb back up, so you'll have to go back through the temple, across the ledges, etc., to get back to this side of the valley.  Or save, the game manually and reload to place Lara back at CHECKPOINT 17.

Pick up a large medipak in the recess behind the stone columns on the right just beyond the broken bridge.  (This is the spot where the first 3 raptors originated.) You can also catch a glimpse of the second artifact on a ledge high above that area.  You'll be getting that shortly.

If you continue to the end of the valley, you will cross CHECKPOINT 11 again, near the tunnel opening where you entered this area.  There's a set of 50-caliber clips here and a small medipak beneath the waterfall to the left (if you didn't get them earlier) and another small medipak on the ground between the twin falls on the other side of the valley.  When you have everything, return to the square, carved stone block and wooden ledge where you dropped down earlier.  Jump onto the carved block—or climb onto the rounded rock to the left then take a running jump onto the carved block—and then jump to grab the wooden platform.  Pull up and then climb up onto the ledge above.

Enter the room with the uneven floor, where you were before, and climb the ledges on the right.  Step out onto the broken wooden bridge.  Take a running jump to grab the other side (press Interact for a saving grab if Lara only grabs with one hand) and then pull up.  Go into the ruined room ahead to get a large medipak.  Then return to the opening.

Go around the hexagonal column on the right and grab onto the lowest handhold.  Climb around to the left and drop to grab the handhold below.  Climb to the left just a little and jump up once.  Climb to the left then jump to grab the handhold in the corner.  Climb around the corner to the left, jump up, then jump back to grab the ledge behind.  Climb to the left, jump to grab the ledge above and pull up.

ARTIFACT #2: Now a small side trip to claim an artifact.  Turn right and take a running jump over the slope to land on the dark hexagonal stone ledge beyond.  If you jump right at the edge of this ledge, Lara will make it past the slope.  If Lara falls short and starts to slide, either complete the sliding sequence (below), climb back up and try again.  Or, save manually, reload at the previous checkpoint and try again.

Once you make it to the dark hexagonal ledge, look down to spot the artifact.  Hop down onto the stick-covered wall with the light stone edges.  (Lara won't grab the edge.) Then drop down and take ARTIFACT #2.  Climb over the wall to where you got the large medipak earlier.  Go around to the right and repeat the climb back to the ledge near the slope.

This time jump onto the slope, slide and jump to the next slope, then slide nearly to the end of the second slope, jump and grab the horizontal pole ahead.  If you miss and Lara lives, you can climb back up via the carved block and wooden ledge, cross the broken bridge, climb up and try again.  Once you master the slopes and reach the horizontal poles, swing from the first pole to the second, then to the wooden ledge ahead.  Pull up and jump to the next wooden ledge.  Enter the tunnel and cross CHECKPOINT 18.

BACK THROUGH THE CAVES TOWARD THE START: Ahead, between the rocks, is the tunnel where you slid down into the valley earlier.  You can't reach it now.  So head to the left and follow the tunnel through various twists and turns to an opening on the right.  Pass it and continue up the slope and around to the right to a higher opening and CHECKPOINT 19.  Slide down the ramp and jump across the deep pit to grab the handhold on the wall ahead.  Jump back to grab another handhold below the slope.  Drop down once and traverse around the corner to the right.  Jump back to land on the wooden ledge.  (On the far side of the pit, you can see the ledge where you got the large medipak and killed 2 bats earlier.)

Go around the corner to CHECKPOINT 20, on the ledge overlooking the wooden ramps.  (This is the same as CHECKPOINT 9 on the trip toward the valley.) Drop and hang from the ledge.  Climb to the right and around onto the small stone handhold.  Drop to grab the handhold below.  Jump back to grab the wooden pole.  Then swing over to the wooden ledge.  Get that shotgun ammo now if you have room for it.

You'll have trouble if you try to jump all the way to the lower wooden slope.  So jump to grab the handhold on the right, which is a little closer.  Jump up to the handhold above, climb to the left and drop onto the slope.  Slide and jump to grab one of the handholds on the wall ahead.  Jump up to grab the one above.  Climb around the corner and jump up twice to reach the ledge above.

Cross this ledge, pick up the other box of shotgun shells if you didn't get it earlier and head down the steps to CHECKPOINT 21 (same as CHECKPOINT 8).  Ahead on the left are 2 vertical poles, one tall, one short, a wooden slope and an opening.  Climb up the taller pole, jump onto the slope, jump to perch on the shorter pole and from there jump into the opening.  (Or climb the short pole, jump to the slope, jump back to perch on the pole and then jump to the opening.)

Cross the wooden ledge toward the slope.  If you didn't get the small medipak in the area below on the left the last time you passed this way, you can climb down the wooden handholds on the wall to get it now.  Climb back up the same way and slide down the ramp.  Drop to the ground, taking a little of damage, or jump across to the stone and wood structure and climb down.  (This is the area where you killed the bear earlier.)

Duck to pass under the low rock overhang and follow the tunnel to CHECKPOINT 22 (same as CHECKPOINT 7).  Climb through the raised opening to emerge above the pool.

OPEN AREA WITH WATERFALL AND HUGE MACHINE (again): Now that you have the THIRD COG, you'll need to take it to the top of the machine.  From here, dive or jump into the pool, climb out of the water and then climb up the ladder.  Use the moving wheels to swing across to the ledge where you placed the second cog.  CHECKPOINT 23 registers here.  Grab the narrow ledge and climb around the corner to the right.  Jump up, then jump back to grab the higher wooden ledge.  With the second part of the machine running, there's a rotating wooden platform protruding from the big wheel ahead.  Wait until the platform is almost level and then run and jump onto it.  Keep running and jump to the small wooden ledge beyond.  Place the THIRD COG on its shaft and pull the final switch to fully activate the machine.

A cut scene shows the massive stone sluice gate being lowered into place, damming the stream above the falls.  With the flow of water slowed, the passageway behind the waterfall is now accessible.

CHECKPOINT 24 registers after the movie.  Dive or jump into the pool but don't head for the exit yet.  Instead get out of the water and climb the rocks above where you got the first cog (to the left of the falls when facing them).  Climb the handholds and ledges to the top of the falls.  Roll under the big wooden log and follow the path forward and around the corner to CHECKPOINT 25 (same as CHECKPOINT 2).

UNDERWATER TUNNEL TO RELIC: Now that the stream isn't running quite so quickly, you can jump into the water and not be swept downstream.  Find the underwater tunnel opposite the stairs near the checkpoint.  Swim through to a small room where you'll find RELIC #1, the Kero Mug.

NOTE: If the tunnel opening has bars across it, then you missed a switch earlier.  Surface, swim downstream toward the sluice gate and climb out on the right.  Turn right and follow the path back to the steps.  Now follow the instructions at the beginning of the walkthrough to get from CHECKPOINT 2 (now 25) to where the SECOND COG was.  If you destroyed the wooden bridge earlier, just grapple-swing across to the ledge.  You'll get another CHECKPOINT there.  Continue to the switch, as described.  Use it to raise the bars blocking the underwater tunnel.  Then drop into the water, head downstream to the tunnel and get the relic.

After obtaining the relic, swim back out to the stream.  Surface and head downstream to the sluice gate.  Climb out of the water on the right, roll under the log and then jump or swan dive into the pool below.  Climb out on the steps between the waterfalls and follow the passage to the end of the level.

*ABOUT ARTIFACTS & RELICS: Finding artifacts and relics (formerly known as "secrets") unlocks various extras like outfits and concept art.  A complete list of these bonuses and how to get them will be added soon.

**ABOUT TIME TRIALS: After completing a level, you will be able to replay it in Time Trial mode to unlock cheat codes.  Again, more info will be added about this once the main walkthrough is done.
