Guard Room Key-
From where you drop into the water, turn around and then swim forward, into the far-right corner to find the Harpoon Gun. Scavenge the rest of the Harpoon ammo scattered at the bottom of the icy lake and then swim over to the giant cave entrance. Climb up onto the ice platform on your left while looking at the cave and then draw your guns and take out the Tiger in the cave and the Shark in the water. Jump towards the ground n front of the cave and then head forward and grab the two Shotgun Shells. When you grab the farthest Shotgun Shell, watch out for the rolling boulder, then enter the area that the boulder came from. Head to the left and take out the next Tiger you see and be prepared to dodge another two boulders near the area around a box of Flares. There will be two more Tigers in the cave, so be careful and take them out before they hunt you down. Don't forget to grab the extra Shotgun Shells in the cavern and then go back to where you encountered the two boulders. Run up the icy slope, either running around the pit of jumping over it, and then jump out of the way as two more boulders start their run towards you. Head into the next opening on your right and then run to the back of the area and climb up the icy wall to the top. Enter the building and then run up the sides to the top, taking out the two Goons along the way. Enter the open door and walk into the next icy area. Take a few steps back from the edge of the ice and then run and jump over to the other side. Grab the big box on your right and pull it backward once. Now, climb over the box to the other side and push the same block towards the ice wall. Now, turn around and pull the next box backward once and climb up on top of it. Finally, you can now jump down to your left and run around the box into a hidden alcove to find some goodies. Once you grab the loot, return to the very first box you pushed and climb up on top. Climb up the ice wall to the upper area and then turn around to find a "zip" line and a Medi Pak. Grab the Pak and climb up the wall to the "zip" line. Once you reach the line, a huge bird will swoop in for the kill. Take it out and finally grab onto the "zip" line and ride it to the end. Draw your guns and take out the two birds once your ride is over. Jump up onto the ice platform and grab the Shotgun Shells and then jump again to the ledge on your left. Walk to the end of the ledge and take out the Tiger you see prowling around. Drop down and follow the path to the right and then drop down again to the lower level. Follow the pathway past a switch and another Goon and enter the small room at the end to find the Guard Room Key.

Shaft B Key-
From where you grabbed the Guard Room Key, follow the hallway to the switch you passed on the way to the key and activate the switch. Return to the two glass windows located at the end of the "zip" line and then shoot out the right window. Head to the left and then push the box forward and enter the new area on your right. Walk forward to the edge of a large pit and then make a running jump across to the far side. Grab onto the edge and then haul yourself up and jump over the ice slopes to an area at the side of a building. Grab the Automatic Pistols and then climb up into the building. Run forward and then you'll be back at the broken window again. Now, use your Guard Room Key on the lock and enter the next room. Take out the Goon and grab the ammo in the room, then exit through the next door. Run to the right and grab the Medi Pak and then climb up onto the ice ledge on your left. Walk to the left until the view changes and then slide down the slope to the narrow ledge below. Take out the Goon in the cave, the bird attacking you from about and the Tiger in the cave. Once you're safe, head into the cave and grab the Medi Pak. In the cave, you'll also find a Snowmobile. Instead of hopping on the Snowmobile, drop onto the next lower ledge to the right of the cave. From here, climb down the icy wall to the ground below. Take out the Tiger and then head to the far side of the area. Climb up the next icy wall you find and take out the Goon when you reach the top. Now, look around and you'll see three icy windows across the way. Shoot out the windows and then jump across the gap and enter the area behind the windows. Head to the left and then climb up onto the ledge and enter the next area. If you want, turn around and try and shoot the Snowmobile Goon that appears near the icy windows. Now, jump across to the platform on your left and enter the small alcove on your left to find a switch. Activate the switch and then turn around and shoot the next Goon that comes out of the building. Enter the building and then activate the switch in the room. Once done, you can leave the room to find the room full of water. Dive in and then swim down the underwater tunnel. Follow it through the door before it closes and then surface into the next room. Walk to the left and climb up the ice blocks to find two break-away ice platforms. Run across these platforms and quickly jump to the next series of break-away platforms just below and to the right. Run across these to the end and grab the treasure on the ledge and then shoot the "Ice Phantom" on the high ledge. This will cause two giant boulders to crash through the ice floor, revealing a new area far below. Now, return to the beginning of the area and you'll see a sloping ledge leading down to the area below. Start the slide and then jump onto the ledge on your right, just before you reach the end. Now, draw your guns and take out the three Ice Phantoms roaming around from the safety of the high ledge. Once they are gone, drop down to the ground and enter the icy hallway to your right. Take out the Tiger in the area and then return to the big area. Search the area and grab the Golden Skull from the floor. Once you do this, three Goons will appear in the area. Quickly take them out and then return to the long hallway where the Tiger was found. Find the ice wall in the hallway and climb up to the top. Now, return all the way to the Snowmobile Goon that you destroyed earlier and run into the next area through the open door. Take out the two Goons in the area before they take you out and you'll see another closed door. Climb up onto the ledge on your right and then head to the right and activate the next switch to open that door. Return to the Snowmobile and then hop on board and follow the icy passage to the end. Take out the two Goons and then grab the Shaft B Key from one of the Goons.

Completing the Level-
From where you grabbed the Shaft B Key, run to the end of the area and then use your Shaft B Key to open the door. Take out the Tiger and then run into the next room and activate the switch in the room. Now return to the Snowmobile and run into the new open door. Shoot the Goon behind the door and then run further into the building to find two more Goons. After taking them out, proceed outside to the huge building. Take out the bird and then head to the center of the building and activate the switch on the wall. Now, run to the opening at the far side of the building and jump down into the hole and into the water below. Swim along the waterway and then shoot the Ice Phantom on the ledge and finally jump up onto the ledge to complete the level!
