Level 1
The Cold War.
The level begins with a drop into cold water. There's a great white shark in the pool. The chicken way is to swim to the square ledge with the flares near the each and climb out quickly and shoot him from here, then go and clear the pool of goodies.
The brave way is to grab the nearby harpoons and head for the underwater crates behind you to find the harpoon gun. The shark moves in quite quickly and has sharp teeth, so don't hang around. Once the shark is dead, swim to the back corner of the pool opposite the area where you found the harpoon gun.
Either way when it's safe.
You'll see two barrels on the bottom. Behind them and to the right there's an underwater tunnel in the ice containing Secret #1: gold coins. Retrieve the several loads of harpoons that you probably didn't bother to pick up earlier and head to the beach area. Climb out onto the small square ledge near the beach and pick up the flares.
Kill the leopard prancing around before hopping over onto the beach. Just inside the cave is a slope with 2 boxes of shotgun shells. When you take the one that's further in, a big snowball rolls down from inside the cave. Jump aside to avoid it. Push or pull the movable crate to find a small medikit underneath.
Turn towards where the snowball came from and you'll see two cave openings. Take the one on the right and prepare for a leopard charge. There are more shotgun shells at the rear of the cave. Go back towards the exit down the right hand side of the cave until you come to an opening on the right. There's another leopard in the cave beyond. Kill it and continue forward down the slope.
Turn left to face the flares on the ground. When you pick them up, immediately side flip to the left to avoid the rolling snowballs. Grab the shells from the back of the cave and the return to where you found the flares. Continue forward toward where the snowballs came from. As long as you don't stray to the right, the remaining snowballs will pass by harmlessly. Turn around and enter the cave to the left of where the last snowballs landed.
A leopard lurks on the left. Pick up some shotgun shells from here and return to the snowball slope. Go up the slope toward where the snowballs originated.
The gap ahead isn't deep; you can easily jump it.
Run up past the shallow alcove on the left to avoid more snowballs coming in from ahead and from the right. Ahead on the left you'll find more shotgun shells. Come back down the slope and turn left into the opening opposite the alcove where the snowballs landed.
Go to the back of this cave and climb the ice ladder to the top.
When you approach the large medikit on the ground, a door at the top of the room opens and a goon in a white suit enters. Take him out and proceed to the top of the room to fight it out with a mercenary, who comes in as you approach. Don't forget to search the bodies for 2 sets of M16 clips.
Go through the door and take a standing jump over the snow bank. There's a movable crate on the right. Pull it once, go around or over it to the other side and push it once. Behind it is another movable crate. Pull this one once to reveal a low, narrow cave containing a small medikit and shotgun shells.
Climb onto the first crate and up the ice ladder next to it. Grab the small medikit on the rock next to the zip line handle. Follow the zip line out to the edge of the cliff for a nice view and a pack of flares. If you hang around for a little while, a pesky eagle will fly in. Take a few pot shots at the leopard down below and head up to the start of the zip line while you wait.
Grab and hold the zip line.
Ride it all the way to the end to land in a shallow trench on the other side of the deep chasm. Kill 2 more eagles (plus another if you didn't meet the one at the top of the hill). Walk toward the building. If you didn't kill the leopard from up above you need to do it now... If you stay down in the trench, you can kill it safely.
Climb onto the icy ledge near the window. Turn around and look to the right. There's a flat ledge in the ice wall that you can jump to. Jump across, walk forward and turn left but walk forward slowly. As soon as you hear the snowball start to roll, hop back, and it will sail overhead. Continue down the trench. In the pit beyond the zip line you'll find the M16 assault rifle. Return over the ice wall to the trench on the other side. Near the end furthest from the building (on the left) is a flat spot you can jump up onto to get some shotgun shells. From there, jump into the depression ahead.
Climb onto the ice block ahead on the left. Below you is the deep chasm you passed over earlier. Hop down to the safe ledge below and then turn around, drop and hang from the ledge and climb the ice ladder to the bottom. Follow the long tunnel, killing a leopard along the way, to Secret #2: gold bars and 3 boxes of shotgun shells. Do not drop down the wood lined hole at the end of the passage. Backtrack down the long passageway and climb back up the ice ladder you just came down. Head right and take the short passage between the buildings, bearing right with the path. A guy in white comes in from up ahead. Kill him and take his M16 clips. At the far end of this path, behind some overturned barrels, you'll find the guard room key. Take it and return to the barred gate at the bottom end of the path.
Pull the switch in the barred alcove to open the door on the other side of the bars. This scares up a mercenary, but neither of you can shoot each other at present. Return to the icy path by the side of the zip line chasm. Go down the path to the first ice window. Shoot it out, enter and unlock the guard room door. Kill the mercenary who turned up earlier. Pick up automatic pistol clips and shotgun shells from the floor of the guard room. Exit through the door where the mercenary entered and follow the path to the small medikit.
Return back through the guard room and continue straight ahead to a movable box. Push it out of the way and go into the dark, snowy area on the right. Take a standing jump up the slope, then a running jump across a hard to see deep pit to grab the opposite edge. Pull up and continue forward. Climb onto the step, turn right, and jump over the ice hill to land in a depression where you'll find the automatic pistols. The exit door opens when you pick up the guns. Take the automatic pistol clips on the nearby ledge and go through this room to the snowy area between the buildings. Ahead and to the right, through an opening in the rocks, is the door to the guard room.
Go through the guard room, out the door opposite the barrels, and along the snowy path (toward where you got the small medikit). Along the left side of this path is a snow ledge that dips down it the middle. Step up onto this ledge for a panoramic view. Get Lara's viewpoint back and check out the three mercenaries below: one in a cave on the left, one behind the wooden structure away to your right (walk up the bank to see him), and a white suited one below to the right. You can take a few pot shots at them if you like, but they're not easy to kill from up here, so it's easier to take the battle to them...
From the lowest part of the snow bank, look down and you'll see a short ramp between the cliff side and the longer ramp leading from the cave on the left. Jump backwards off the snow bank, slide and grab the edge to safety drop down onto it. Shoot the eagle that comes in from above and take out the mercenary in the cave. Don't rush in to search his body as there's a leopard inside. When it's dead, pick up the M16 clips from the mercenary and a small medikit lying on the ground. Pull the switch to open a door in the back of the cave on the other side of the chasm. You'll also find a snowmobile parked in a room off to the left.
Before taking the snowmobile ride, climb down the ice ladder on the left side of the ramp. At the bottom are shotgun shells and flares, being guarded by a leopard. Back flip over the leopard's head from the ladder, drawing your guns as you go. This should help you avoid being torn to pieces... If you want you can go to the end of the ramp and kill the baddies over the other side with the M-16 from long distance. (I found it easier than fighting at close quarters) Now climb back up to the snowmobile and jump it across the gap (using turbo power), or climb up the ice ladder on the other side of the chasm (in which case, you'll need to be ready for another mercenary at the top).
Assuming you jumped the snowmobile across to the other ramp; take out the white-suited mercenary if you didn't kill him from above. Dismount and pick up his M16 clips. On foot go through the open gate. Climb onto the first block and await the arrival of another goon on a snowmobile. Take him out from up on the block, since he can easily follow Lara through the door and run her over. One block has M16 clips on top; there are automatic pistol clips on a snow ledge next to the door on the right, and more M16 clips and a large medikit on one of the other blocks. Take your snowmobile of choice and exit through the door on the left. Follow the path to the top, killing the mercenary there, if you didn't do it earlier. Take his automatic pistol clips.
Ahead is a ramp with three ice windows. Drive the snowmobile up the ramp (mind the gap between you and the ramp or you'll crash into the pit), bust through the windows to the area on the other side. You can ride through the single ice window opposite to take on another armed snowmobile. In this case be sure you've got one of the snowmobiles with guns and not the unarmed one.
OR
Dismount and climb into the wooden opening without windows on the left. Soon the snowmobile will ride in and you can kill him from here.
Climb through the wooden opening on the left side of the first open area. Beyond is a building and a frozen pool. Find the switch in the dark corner on the left. Pull it to cause an avalanche that breaks the ice on the surface of the pool. This also alerts the mercenary inside the building, who comes out to investigate. Kill him and take his small medikit and M16 clips. Go into the building and pull the switch to open the wall of ice back in the snowmobile area. Exit the building and wade into the pool. At the deep end, swim down and follow the underwater passageway. The door opens as you approach and closes behind you. Surface in an underground cave and note the items on the shelf above the water. Climb out on the rocky shelf opposite and check out the ice cavern.
At the far side of the cavern, there's a large medikit up on a tall block of ice. Find the angled wall to the left of the block with the medikit. Stand Lara with her back to the slope and her chest against the medikit block. Back flip onto the slope and then quickly jump and grab to catch the edge of the block. Pull up. When you pick up the medikit an avalanche redistributes the landscape around you in a big way – but you're safe where you are. You may have noticed a few ghostly men walking around below your feet or standing up near the medikit before the avalanche. These "restless spirits", will help Lara fight her enemies and generally try to lead her in the right direction, so don't harm them. If you do, they will attack.
The avalanche caused the pool where you entered the cavern to freeze over, allowing to reach the goodies you noticed earlier. The hard route back to the frozen pool either take the zigzag path made up of thin ice sheets leading from the medikit tower (the corners of the zigzag are solid).
OR
The easy route is to take a running jump to the snow ledge on the right (Lara's right when she's facing out into the cavern) and go right at the mound of clear ice and follow the path counter-clockwise along the wall of the cavern. Jump over the gap halfway round and continue on to the frozen pool. Get the Uzi clips and grenades from the ledge. Slide down the ramp of bluish ice to the floor of the cavern. There are 3 more ice men here to assist you later. Head across the floor of the cavern to the ice cubicle containing Secret #3, a gold skull. Shoot an ice panel to get at it.
When you pick up the skull, 3 mercenaries enter from the tunnel to the left of the ramp. The ice men will help you fight them. Once the mercenaries are history, search the bodies for shotgun shells, 2 sets of Uzi clips and a small medikit. Go through the right hand ice window on the left of the entrance slopes into a long, U-shaped tunnel. A leopard will charge, but you should have plenty of time to bring it down before it gets to Lara. Be careful not to hit the spirit men, who are also in the tunnel.
Continue along the tunnel to the top. Turn right and climb the ice ladder to the top. You emerge inside the building beside the pool. The door opens automatically. Go through the building, cross the pool and climb out through the wooden opening. Continue straight on to the area with the ramp, which was previously concealed behind the ice windows. Two bad guys - one in yellow ahead on the right, one in white just inside the entrance on the left make things difficult for you. Kill them, and take their stuff: M16 and automatic pistol clips. Pick up the flares on the block near the wooden gate.
There's another white-suited guy beyond the gate. Open it using the switch up on the ledge to the left of the opening where you entered (looking back from the gate). Kill the goon, and pick up another small medikit. Now return through the wooden gate and climb onto the stone wall to the right. Get Lara's health up to 100% - you're about to take a long drop. Position Lara on top of the wall (near the gate) so the gate is on the right and the low, flat section of the jagged wall of snow is in front of her.
Take a running jump and when you land, immediately jump right to spring off the slope, land on the sloping ice wall to the right, and slide down backwards. Grab the edge, shimmy as far as you can to the left and drop. You can also manage this by simply jumping forwards as you land from the first running jump, but the margin for error is much less... Once you've made it to the floor of the chasm alive, pick up Uzi clips, a large medikit and the Uzi's. Climb the ice ladder near where you picked up the Uzi's and you'll emerge on the other side of the ice window in the snowmobile area.
Head to the left, then left again to trek back to where you killed the last white suited mercenary. Grab a snowmobile on the way (although it's possible to continue on foot) and as you head through the gate and up the steep slope, give the snowmobile some gas to jump the hidden pit. You'll land on the other side near a wooden block. Stop here.
(NOTE: If you're on foot, you can climb up the wall on the right to jump to the top of the steep slope.
Then drop down or jump across the pit.) The next area, a slope down to the right, is also a snowball trap. Stay in the middle of the slope and the rolling snow will miss you. Go through the doorway into a series of connected rooms. As you go up the hill, a mercenary in white comes to meet you. Kill him; take his automatic pistol clips and the large medikit on the ground a little further on. When you pick up the medikit, another mercenary comes in from the snowball trap area, so stay alert. Dispatch him and take some grenades and the shaft B key off the body.
Continue to the top of this series of rooms. Use the key to open the wooden door next to the lock. Enter carefully - there's a leopard just inside. If you accidentally fall off the walkway, it's not a long drop, but it puts you way back at the guard room area. Cross the walkway to the room beyond. Admire the view, and then pull the switch to open the metal door back near the shaft B lock. Return there and take on yet another angry mercenary. He's carrying a pair of grenades.
There's a box of shotgun shells on a box in the next room, but you'll probably need to take out 2 more mercenaries in the room beyond before getting them. One of these guys has a small medikit, the other shotgun shells. An eagle flies in from above as you're ransacking the last two corpses. Further along, is a covered structure with a switch. This opens a nearby trapdoor. There's a sniper on top of the high structure beyond the switch area and a second sniper appears when you throw the switch. You can take them out together, or kill one, throw the switch and kill the second.
Drop through the open trapdoor into an icy pool below. Swim through the wooden opening toward the ledge with the ice man to end the level.
