Turn around and climb down the wall to the bottom, then backflip to the hidden ledge where you will find a third switch. Flip this, then jump back to the ladder and climb to the ledge on the right. Jump to the slope near the middle of the large room, and grab the edge as you slide. Shimmy right until you can backflip to the central column, then jump up to the monkey-swing and exit into the new area with the plane. Jump to grab the limb, then again to reach the plane. Go inside and kill the raptor, then use the keys in the cockpit to turn on the power. Head further into the plane and flip the switch to extend the big gun and fire on the raptors outside. The gun will also blast holes into the walls in the building across the river - go through the hole in the wall to exit the level.
Start by exploring the starting area and taking care of the bats. Kill the dragon in the tree, and another one under the ledge in the gorge. Climb down the pillars, then jump over to the large block in the centre. You can now jump over to the rocks and grab on. Shimmy right and flip the switch to open a door back at the beginning of the level. Now shimmy left, then drop and grab the lower ledge. Jump over the sloped area and land on the flat ledge near the opening in the rocks. Head past the sealed door and do a safety drop to the ledge. Jump and do a backflip over the razor grass and crawl into the dark space. A dragon attacks as you collect the save gem - watch for another one as you leave. Head to the stairs and take care of any resistance you encounter. Push the button to open the sealed door, then go down the passage beyond the door to find a waterfall. Behind the falls you will find some ammo. A monkey swing provides access to the ledge above the slope. Slide down the slope then jump and grab the pillar, then jump to the middle pillar to get the save gem.
Leave this area and do a running leap and grab the face of the cliff. Climb to the top and head right. Backflip to the slope and grab the edge as you fall off. Shimmy to the right and drop down to the platform to search the shack for more ammo. Do a running jump from the platform back to the main path (grab in mid-air to avoid hitting your head). Return to the main trail and you will see a kayak behind closed gates. Kill the crocodiles, then dive in a flip the switch to open the gate. Climb in and practice your manoeuvring in the kayak. Back-paddle to slow yourself through the first stretch of whitewater and steer toward the pool to the right. Get the save gem, then back on the river, head over the first falls and keep to the right to miss a big rock and a trip line. Continue around the bend and start back-paddling when the current pulls you to the right. Trip the line to turn off the blades, then cruise over the next waterfall. Watch the rock to the left and back-paddle as you steer towards the dark cave and follow it around to the right. Avoid the trip lines and keep back-paddling to steer and monitor your speed. When you cross the final line, make a sharp turn around the corner, then paddle forward through the narrow gap. Dodge the patches of razor grass (keep to the left) then let the current take you to a large cavern. Paddle behind the waterfall to find a save gem and some other items on the shore you can get later.
Now paddle down the green passage and paddle fast away from the crocodile. Get onto the shore and kill him from there, then swing out over the cavern, using timing to avoid the flames. Jump to the ledge and get the rocket launcher, then go up and follow the passage back to the waterfall. Do a running jump over the falls to get the ammo, then head back down the shore and climb up to the left ledge. Jump and grab onto the monkey swing and climb out to the middle until you hear some bats. Turn left and drop down at the wall and get the ammo from the shore on the left. Monkey swing back across the stream and jump around the corner to the slope. Jump to the ledge then jump back and grab the wall and climb up. When you get outside, look to the right for a tunnel and go inside. Dodge the boulders by ducking. When you enter the room with the walkway, walk out a short distance then back off the walkway and shimmy over the fire and pull up at the opposite end to avoid triggering the boulder. Jump over the flames in the hall and avoid the boulder that drops down quickly. Back at the river, run and jump to the ledge on the right and climb into the crawlspace. Once you are through this, jump to the middle platform and then to the far ledge. Ride the cable-slide down to the lower ledge and jump off to land on the ledge. Climb the textured wall and watch for a dragon to attack from the right as you reach the top. Enter the hallway and flip the switch to pull the plug, light a torch and bring another dragon to kill. Return to your kayak and head down the whirlpool, staying on the edges to avoid dropping. When you reach the lower area, use the underwater switch to open the exit and bring 2 crocodiles towards you. Quickly get out of the water and kill them before exiting the level.
Temple of Puna
Kill the natives quickly to avoid being hit by poison darts. If you do get hit, kill as many of them as you can before using the medkit. Go to the lower area and note the gate leading to the boss. Ignore this for now, and head into the larger room with the boulder on the ramp. Kill some more natives on your way up the stairs, and when you reach the top, crawl into the next room. Jump from the upper ledge and sprint towards the right corner as the rolling blades go past. Wait for the blades again, then run to the switch, flip it, and run back to the corner before they return. Now make your way to the next corner by jumping the gap between a set of blades, and repeat the process with the switch. Do this two more times, and the door will open.
Head to the door, then time a run back into the room to collect the save gem. Roll as you grab it and run back through the door. Slide down the slope into the next room with the spiked ceiling. Pull the box to stop the ceiling, then flip the 3 switches to open the door. Drop safely down the hole into the large chamber with the boulder. Flip the switch to turn on some lights and seal the door. Sprint down the passage as the boulder is released, and continue through the door and turn right. Keep to the centre of the room and get the save gem. Keep going to reach stable floor between the two ramps. You wll be attacked by 1 native on the right and 2 on the left. Start up the stairs, and when they reverse direction, you can spot an opening high above you. Jump from the steps to the wall, shimmy to the left and up into an opening to get some items. Go through the gate and slide down the slope to enter the boss' chamber. Keep running to avoid Puna, and take care of his helpers when they arrive, ignoring Puna for the time being. When he finally dies, get the medkit from the ledge, then the relic.
Kill the snake to your right and take the rocket. Wade across the water and enter the passage to find a block to push. Grab the ammo and head up the trail, where you can jump twice to reach the middle ledge, then drop safely to the area below. Kill the snakes here, then grab the ammo. Now go back and push the block from before, then jump down to the platform below. Do a running jump and grab, then continue until you see a metal chute. Head right and jump up to the ledge nearby. Kill the snake hiding in the bushes then run and jump to the next ledge. Run off the end of this ledge to drop to the one below and continue along until you can drop down and get a medkit. Climb back up and continue to the rocks, where you must run, jump and grab to reach the other rocks. Kill another snake and make your way to the top of the chute. Drop into the chute and fall into the water. Swim until you can surface for air and climb out.
Follow the trail leading away from the waterfalls, and kill the vultures that attack. Continue until you reach the high ledge at the same level as the rock formation. Do a running jump across the canyon and climb down the ladder, staying to the right. Drop and grab straight away to cling to a crack in the rock-face, and shimmy right until you can climb up and get some items. Jump into the water below and get all the items underwater, as well as those in alcoves near the waterfall. Exit the water via the red rock near the falls. At the top, jump to the slope opposite, then head down the trail again. Take the upper route this time and kill a snake hiding in the bushes. Jump past the rock and avoid the hole on the ledge. Drop and grab to the crack below and shimmy left to reach a ledge. Jump and cling to the rocks above and monkey swing to the cliff-face, then climb up to the left. Take the save gem, then find the flares and TNT on the ledge below. Head to the waterfall and jump across to the slope. Grab on as you slide off, then climb down and continue along the cliff until you can jump over to the rocky surface and climb to the top. Perform a backflip over to the flat rock, then jump and grab the slope between the pair of waterfalls. Pull up and you will start sliding - jump and grab to reach the ledge. Grab the ammo, then jump to the crack and shimmy right. Drop and jump to do another backflip across the water. Keep jumping along the platforms as you make your way upstream, and you will come across a large cave with a waterwheel. Kill the snake near the boulder on the left shore, then crawl under the opposite rock and go up the ladder to get another secret. Climb to the left, then drop down to the floor and kill the snake.
Return to the shore and find a small room with an elevator. Climb up the waterwheel and follow the channel to an open area, keeping an eye out for more vultures. Dive into the water and swim to the right to find a switch to use - this opens a door leading to some ammo. Flip the next switch to open the underwater passage and go inside to find another switch hidden along the dark wall above. Pull it, then swim back through the passage, pulling another switch as you make your way back to the hall above. Find the final switch and pull it to start the waterwheel. Head back and collect the items from the dry riverbed, and the ledge above it. There is a block here that will let you get behind the falls for some more items. Now return to the elevator room, kill the guard and take the detonator key. Now go back to the ledge with the TNT, and blow it up. Quickly jump left to avoid the boulder, then explore the demolished area and climb through to a new area.
Head around the fence to the left and climb into the dark passage. Continue until the path splits, and pull up to the upper ledge. Jump into the water and swim around to find a pair of switches hidden in the tunnel, behind the pillar. Flip them both then return to the outside area by the fence. Head down the large cave and kill the snakes before flipping the next switch inside the building. Now climb into the dark passage but take the low path. Kill some guards, then jump across the fence to the box and head away from the fence, killing more guards as they appear. Enter the building and dispose of the guards. Use the box and the grating to climb on to the roof of the next building and get the generator access pass. Unlock the door using the access pass, then do a backflip and kill the power to the electric fence. Push the button next to the main gate, then get on the quad-bike and ride out of the area. Head down the cave and jump the fence.
High Security Compound
You start without your possessions - jump into the window to get the guard's attention, and when he comes near, sprint past him and jump the railing outside. When he starts to chase you, run back upstairs toward your cell and flip the switch nearby to release a fellow prisoner (who will kill the guard). Open all the remaining doors to release the rest of the inmates, then return to the cell that was already open and you will find a box to push. Enter the crawlspace and push the next box, so you can push the first one back down the passage and reveal another crawlspace to the right. Pull the second box twice, then crawl through to get a medkit. Take the passage out of this cell and jump and grab the walkway above. Do a running leap over the barbed wire and keep going. Walk through some barbed wire to reach the next switch, then use the ledge nearby to reach the trapdoor. You should see a ledge about halfway down to the left. Head down the dark passage and jump over the first trapdoor, then enter a small room and drop through the trapdoor to enter the Control Centre. Press the button here, and after the battle, get the Security Pass.
Find the dining room and take the door to the left to find some large boxes. Push the moveable box under the hole in the ceiling, and climb up. Jump over the pipe to flip the switch, so you can swim into the room with the boxes and swim into another hole in the ceiling to arrive at the kitchen. Make your way to the room with the red floor, and continue down the walkway avoiding the pits, until you reach a pair of doors. Flip the switch in the yellow room to turn off a fire in the kitchen, then return and drop into the kitchen and open the door at the other end. Go around the corner and open the door on the right. When the guard comes out, sprint back to the kitchen and head right then left into the hall. Run all the way back to the prisoners, so they can take care of the guard. Now return to the door where the guard came from and use the switch to open a vent above the grill. Jump to the crack so you can shimmy left and jump from the slope to the ledge across the pit. Pull up into the crawlspace, then follow the corridor until you spot an inmate in the hall. Continue to the green passage and wait. When the guard moves to the left, sprint to the right and get out of sight before he turns. Head right and dodge the next guard as you cross the open area and make your way to the lower prison area.
Open the cell to free another prisoner and he will run down the hall. Follow him, and get the Security Pass after the guard is dead. This opens a nearby door, which you should go through and continue down the large passage. When the guard sees you, run down the left hall and open the cell to get some help. After the beating, take the key and use it to unlock the door back in the open area. When you come across the guard below, duck and enter the crawlspace and head toward the switch. Wait for the guard to go left, then flip the switch and jump over the red laser to get into the hall before the guard shoots you. Continue down this hall to the next room. Drop from the lowest walkway support beam to the ground, then climb the ladder to enter the corridor with the guard on duty. Ignore the guard for now and return to the red passage. Use the security pass in the lock and climb up the ladder, then push the button to open the small door. Don't flip the switch in this area. Dive into the water and get the save gem, and swim through the passage until you can climb out and jump the lasers to reach the ledge. In the cargo room, climb some boxes to the left to find your pistols and desert eagle in a small room. Watch out for a gun turret as you leave - turn right and sprint to safety until the gun shuts down. Now climb up the boxes, and head through the door to make your way to the main floor by the big dish. Go and kill the guard you ignored previously and take his security pass so you can open the door at the end of the hall. Go through and get the grenade launcher. Return to the cargo room and go up the slope, killing the guards. Climb the ladder and push the button on the right (ignore the left one). Climb on to the box to reach the upper ledge in the cargo area, then monkey swing across to the next ledge. Kill the guard and take his security pass to open the locked gate. Kill the last few guards and climb into the truck to leave this level.
Throughout this level, try to kill the enemies quickly before they can use an alarm switch to call for backup. Get out of the truck and get some items from the crates. Kill the guard, then get the MP5 and use the button to open a grate leading to a medkit. Watch out for laser traps in the next area (and the rest of the level). Enter the crawlspace and head left to get another medkit, then go back to the tunnel as the lasers move away. Wait until they move above you, then run to the ledge and grab and pull up out of their returning path. When the guard moves off to the right, crawl out of the passage and kill him quickly. When you see the laser-trigger turret, avoid it by crawling through the hole in the wall. Continue along the passage and kill another guard, and continue until you find the switch to flip. After you fall, turn left and head to the right of the pillar. Kill the guard quickly or you won't get the next secret. Take the grenades, then drop to the mesh floor and flip the switch to open another trapdoor. Kill the next guard and go through the open gate leading to the crawlspace. Collect the ammo and drop through the trapdoor to the hall below. Dispose of another guard, before heading around the corner. Flip the switch to release a prisoner, then get the medkit from his cell.
Back in the long passage, use the crawlspace to avoid the laser traps, and get another medkit and the shotgun in the process. Kill the guard next to the buttons, then kill guards from both sides as you approach the door. When they are dead, search their hiding places to find a switch, which opens a crawlspace in the other. Continue up the corridor and trip the green laser to activate the alarm - kill the guard who arrives. Head right at the fork, and kill the sniper over by the missile. Now get the code clearance disk and go back to the fork. Take the left passage, and jump over the lasers to reach the console. Use the disk to get the missile out of the way, so you can get the ammo from the ledge. Do a running jump to the ladder between the missiles and climb up. Backflip from the top and kill the sniper in the corner, then jump over to his location to get the hangar access key. Drop on to the platform at the other end of this ledge. Shoot the grating and crawl into the tunnel to get a save gem. Return to the missile bay and find the passage on the ground floor. Avoid the hole in the floor (you'll come back here later), and use the hangar key when you reach the lock. Kill the guard on the train platform before dropping down near the electric rail (which you don't want to touch). Climb up the mesh and push the button to call the train. Jump from the ledge to the train then jump to the hall above to monkey swing over the gratings that open up as you pass by. Keep an eye on the lasers and wait for them to move away before dropping down just as they reverse and come back at you. Kill the guard who is running away, then continue up the hall into the next area.
Go around the UFO, avoiding the green electric eyes. When you reach the boxes, climb up to the opposite passage and kill the guard. Press both buttons and kill both guards who arrive. Now push the left button, then quickly jump right and roll and press the right button. Now use the white top of the console to get to the other walkway, drop to the floor and run out the door. Kill the next guard, then flip the two switches on the right, then the second switch from the left to access the UFO. Return to the UFO and push the button before climbing the ladder. Backflip from the ladder to the rafters then run and jump across the rafters until you reach the catwalk above the UFO. Get the launch code and go through the hole in the floor from before. Use the code to access the button. Push it, then quickly jump left and roll, and start sprinting. Return to the area where the missile used to be and kill the guard who arrived. Open the passage and enter as the door seals behind you. Continue past the laser trap and kill the sniper and some more guards. Get the key to the UFO and finally flip the switch below to open the trapdoor. Return to the area with the UFO and climb back into the rafters. Head past the walkway leading to the UFO and do a running jump and grab to the open door. Get the save gem, then go outside and use the UFO key to get inside. Kill the guards, then get the relic from the upper area.
Dive down and get the ammo, then exit to the shore and follow the coast past the locked hut. Jump over the water near the ship, then swim and pull up to the icy ledge. Swim once more to reach land near the front of the ship, then climb the cliff to find a monkey swing. Use this to cross over, then drop to the ledge an enter the ship via a hole in the deck. Kill the sailors and make your way to the mechanical room. Flip the switch on the left of the machine to open a trapdoor, then drop through and continue killing people. At the next junction, note a hole in the ceiling, then continue toward the orange pipe and kill another sailor. Drop through the trapdoor and continue fighting. You will eventually see a small boat (Zodiac) outside - press the button to release it into the water. Now return and climb through the hole in the ceiling, then turn right and follow the cliff. You should spot an opening in the cliff, where you will find some ammo. Make your way to the rear of the ship and jump into the Zodiac.
Manoeuvre the craft around the ship, past the cliff and down the channel past the hut then get out when you reach the ledge inside the tunnel. Light a flare and then slide, jump and grab the ledge. Climb up into the crawlspace and head right to find a medkit. Go back and drop into the water, then swim down to get some ammo, and back up to get into the boat. Drive further down the tunnel until you reach a gate. Exit to the shore and kill the approaching enemies, then monkey swing using the bars and head right at the junction. Drop down and continue, killing more men and dogs, and you will reach a building. Press the button on the wall, then circle left around the building. Drop into the hole, then swim left and exit near the fuel valves. Wade through the water to the ladder and climb up to the generator room (which is locked).
Head outside and follow the path to the left, past the kennels, and kill the men. Get the ammo under the bridge, then head back to the area with the hole you dropped into earlier. Enter the nearby cave and kill more guards, then roll to get through the doors, and head upstairs to get the crowbar. Return to the hole again and backtrack down the dark passage. Climb up into the raised building and flip the switch, then pry open the door with the crowbar. Drop down and check out the map which shows which valves need to be adjusted. Return to the generator room and flip the switch to start the machines, then go to the kennels and kill the dogs before entering the building. Press all three buttons and get the gate key from the desk, then return to the monkey swing where you left the Zodiac. Go to the building you opened with the crowbar and use the gate key, then press the button. Kill the extra guards as you leave the building. Get back in the boat and continue down the passage, until you can leave it at a landing to the left. Look for a hidden alcove below and to the right that contains the hut key. Get back into the Zodiac and retrace your route all the way back to the hut at the beginning of the level. Use the key to get some flares and a save gem. Now head all the way back through the waterway, through the gate, and exit to shore when you spot the cabin. Fight the guards as you make your way to the cabin at the top.
Proceed down the hall and run right through each of the gates until you hear a second clicking noise, then turn around to find an open passage and head out. Don't attack the guys with flamethrowers and they won't attack you. Head to the first room and turn on the lights in the control room. Kill the mutant, then climb to the top of the control room and drop off the back to shimmy over to the ladder. Climb down the ladder almost to the bottom, then backflip and twist to grab a ledge behind you. Enter the small room to get some ammo. Head back to the previous room and use the middle mine cart. Keep your speed up by leaning into the turns and keeping off the brake, and you will make the jump. Hit the switch track as you go past, and exit the cart when it stops. Crawl under the drills and search the crack over in the left wall, then head around to the left. Kill another mutant then drop to the walkway before dropping safely to the ledge below. Shimmy along each of the cracks as far as you can go before dropping to the next one and reversing direction. When you reach the left side of the lowest crack, pull up into a passage and move forward. Kill the hiding enemies on the way to the open area, where you can get a new crowbar from the metal ledge. Find the crawlspace in the wall near the mutants and investigate.
Go to the rocks on the right, then jump over to the cliff, shimmy to the crawlspace and flip the switch inside. Now proceed up the snowy slopes, finding all the flat areas to make your way out of this area. Enter the passage and duck to avoid obstacles and machines, then head up the slope and kill the mutant at the top. Return to the mine cart and flip the track switch so you can return to the main room with the other carts. Use the crowbar to open the door and get the lead acid battery. Go back to the area where you got the first secret, and go through the newly opened door for some more ammo. Return to the main room and get into the lower mine cart. Head left, building up speed for the big jump, and be sure to duck appropriately. When the cart stops, jump out and head down the passage to the lower hall. Kill all the mutants and search the crawlspace under the walkway with the steam. Crawl through and kill the mutant, and swim quickly down to get the winch starter and back up again before you freeze. Return to the mine cart room and take a final ride on the top mine cart. At the end, you will find a crane holding a mini-sub. Stick the battery in the slot and use the winch starter on the controls to lower the sub into the water. Dive in and get into the sub - reach the surface of the next safe area, then continue down between the lights and around to the right. Ignore the flamethrower guy and drop to the ledge below the bridge, killing the mutants behind you. Keep jumping between the ledges until you reach the corner of the lower ledge. Head back to the bridge and jump up and grab, then pull up to enter the small building.
Lost City of Tinnos
Head to the upper level via the nearby ladder, then flip the switch to open the door below. Jump to the central column to get the save gem, then go down, through the door and get the uli key from the niche off the short hall. Use this key near the black grate in the courtyard to open the next area. Flip another switch (on a ledge near the first one you flipped), then climb up into the building and cross over to the sloped hall. Head down to find and flip another switch, and 5 more will be revealed. Flip switches, 1, 2 then 5 to access the next area near the broken bridge.
Kill the giant wasps, then get the save gem. Climb the ledges here, then jump over to the bridge and find the invisible ledges leading to the wasp nest. Do a running jump to get inside the nest, being careful not to fall into the hole. Return to the bridge and jump over the break, following the passage to the right, and taking the medkit as you leave. Enter the green passage and kill everything. Time your running past the swinging pots, then in the next area, head to the ledge on the left to kill more wasps. Further down the hall is another switch - flip it then kill 3 more monsters. Now head to the next switch, then use the pillar to access a new crawlspace outside. Drop to the walkway and find the switch on the left wall - remember this secret switch. Now flip the switch on the ground floor then climb to the ledge that raises up. Flip that switch and move on to the next ledge until you can spot the platform under the walkway near the entrance. Make your way to this platform then jump up and monkey swing using the bottom of the walkway. Flip the switch here to open the exit. Now flip the secret switch, then immediately run back down the hall and drop off the walkway to the ledge on the left. Drop safely to the floor then move down the hall to flip the next switch. Run quickly towards the column of light and head up the stairs to the right of the bright light. Follow the passage down and to the left, returning past the swinging pots and head across the bridge. Jump off to the right and slide down the cliff to the bottom, running through the door before it shuts. Get the save gem, then flip the switch several times to get back out.
Return to the room with the column of light, and note the rooms surrounding this light. Enter the Earth room, and keep to the right to avoid the quicksand.

Jump along the ledges on the wall and flip the switch, then make one more jump around the corner to the sloped ledge and leave the room. Return to the swinging pots room and you will see a new block to run and climb on to. Do this and get the ammo, then return to the column of light.
Go into the Air room next. Take the first right, then left, right and left again. Head down the angled passage to the right, taking the first left to find a crystal. Turn left here and follow the hall to the next junction, turning right into a wider hall. Head up the ramp to the left, and jump between the ledges to trigger a log trap. Head to the other end to get mask #2, then note the map above your head, which shows the layout of the area. Now start jumping to the ledges and blocks, making your way to the ledge with the switch, which reveals mask #3. Note that some of the ledges are only visible with the aid of the flames from the dragon heads.
Finally go into the Water room. Swim through the blades in the direction they are moving to minimise damage, note the clock, then head to the left alcove to flip a switch and get some air. Head back to the clock and go through the right hole to find a new area. Flip the next switch to open another door, revealing mask #4. Get this and flip another switch, before going to the clock and the left alcove for more air. Now go through the hole at the bottom and the current will pull you to the exit.
Now go to the lower room and place the four masks on the four statues. Get the key from the pool room and use it to open the nearby hall, leading to the next level.
Run in circles around the meteorite so that the spider doesn't get a clear shot at you. Keep shooting it until it collapses, then quickly run down a side passage and get one of the four fragments, sprinting back to the circular path before it awakens. Do this four times, then the next time the spider collapses, it will be for good. Climb the ladder to the top. Walk past the carved face, then drop down and backflip to the hand of the statue. Jump to the middle ledge, and follow the passage to the left. Monkey-swing to the next ledge, then jump around and up to the surface. Slide down the slope and turn right, being prepared to kill a whole lot of bad guys. Push the button on the wall, then follow the path to the left, go through the gate and run to the helicopter.
Climb the metal ledges and make your way to the centre structure. Jump to the slope for some flares, then jump to the centre platform and monkey-swing out over the cathedral ceiling and drop. Get the medkit from the landing (and use it!) and some more flares from the purple platform. Head to the walkway above the bookshelf and use the switch in the alcove. Drop to the floor, then climb and jump to the centre structure. Do a running jump and grab the ledge, then shimmy left to flip the next switch in the upper alcove. Head down the hall from the floor, and keep running to reach another switch at the end. Return to the main room using a monkey-swing over the spikes. Return to the bookcase and swing to the left. Drop and grab so you can climb into the small area at the other end of the monkey-swing, and up above the cable slide. Get the Vault Key, then use the slide, dropping off as you enter the light. Climb on to the area above the pillar, then drop and hang from the other side to see an open door. Monkey-swing across, and drop into the water after you catch on fire. Swim past the piston and push the button, the grab the medkit from the ledge to the right. Above the ladder, do a quick roll and grab the edge to trigger (but not fall through) the trap door. Jump across the hole and head to the vault. Use the key to open it up and shoot out the grates before dropping into the water. After you surface, kill the man and his dog, then collect the items to end the level.
