Behind you is a locker with painkillers. Door to the left is closed, take the door to your right. You pass a ventilation shaft on the left, which you can smash, but we’ll get back to that later. You enter a room with four cabinets. There are two flares on the left. Get out the way you came from and go right. You pass another ventilation shaft. Go forward and you enter another room with cabinets. You find a flare, batteries and beef jerky on one cabinet. On the right there’s a green box hanging on the wall, in which there’s a key you must take (approach the box from the right and move the cover to the left). Go back and smash the first ventilation shaft you see (on the right). Crouch and move forward. Smash another shaft in front of you. You enter a room with a box hanging from a machine. Go to the control room on the right. There’s an artifact, so you can save your game. There’s a book in one of the lockers. Now use the controls to move the box to the far left side of the room, so that when you jump on another box you will reach the ventilation shaft under the ceiling. After you reach and smash the shaft move forward and don’t fall down after you turn left. Keep crawling until you see another shaft. Smash it and fall in the room. Pick up the gasoline canister. Watch out for the steam. Now you must get out of the Storage.
Remember the fence blocked with a wooden plank? It’s near the place where you first walked into this part of the mine. Anyway, use the saw on the plank and cut it. Walk through the door. Go left and kill the dog. Head to the Auxiliary shaft. Before you take the last left there’s a table and a note on it in front of you. Go into the Auxiliary shaft. Save the game using the artifact on the far left. Grab each ends of the power cable and stick it to both sockets (the power cabinet and the table). Insert the key you found in the Storage into the hole on the table next to the joystick. In the inventory use the hammer on the gasoline canister to open it and then use the canister on the big digging machine. Use the key to start the machine and push the joystick up. The machine will dig through the wall and uncover a door on the right. You enter a new part of the mine…

Use the wooden planks to get to the other side without falling down. Turn right and approach the door. Now here’s the scary part: you hear some noises and after a few seconds the door will be smashed by a HUGE worm. Run back and step on the planks. The worm will fall down. Walk into the room the worm just came out. The door on the left is closed. Go right through the tunnel. Take the first left and kill two spiders. I hope you have at least one dynamite to destroy all eggs and spiders on the left. Go forward and turn left, there’s a room. Pull the lever in front of you and run back to the room where the worm came from. The closed door is now open. You enter a new part of the mine again…
Go forward and take the first left. There’s a map on the wall. Go to Shaft 13 and kill the dog on your way. On the bridge turn right into the tunnel. It collapses after you walk in. Go forward and always stick to the left side. There is a lot of spiders and spider eggs, but you don’t have to kill them all. Eventually you walk into a room with some lockers. Roll the big rock on the left to block the way you came from (spiders won’t go in). There’s a note on the bench. Pick up all things from the lockers. In one locker on the right there’s a helmet under which there’s a blank note you must take. Get out of Shaft 13.
Look at the map and go to the Tool storage. From there pick up a screwdriver and wire cutters. Opposite the Tool storage is Section C, but you don’t have the code yet.
Look at the map again and go to the Refinery. Kill the dog while you’re at it. In the Refinery go up the stairs on the left. Push the buttons until all three crushers are up. Crawl under them. Pick up some things from the little room on the right. Grab one rock and put it on the rubber tape under the crushers. Go after it. Now put the rock on the other tape and go back to the other side. If you’re quick enough, you’ll see how the rock drops down the ladder. Go up the ladder and push the button to the left. A tape at the bottom to the left of the crushers will be uncovered. Go to the little room under the ladder and pick up the red object from the cabinet on the left. It’s a motor. Drop it onto the uncovered tape. Go up the ladder and use the rock to block the fan so that it will eventually explode. Go through the shaft. Put the motor that arrived on the tape into the space opposite the sign. Use the button and get on the tape. Now you must get to the other side of the room without being killed by the steam. Each time the steam shows it appears at different squares. You can count them and find a safe route to the other side. After you successfully get to the other side, move the barrels to uncover the shaft, because the door upstairs is closed. Smash the shaft and crawl inside. Take the first right and go a little way up. Use another shaft to get out. You are now in Shaft 12 that was previously closed. Move the cart blocking the door, but don’t go outside. Turn around and go down. Jump onto another cart and use the wire cutters to cut the wires blocking the cart. Push the cart down. The cart smashes a wall. Go inside. You enter a room that looks like a classroom. There is an artifact on a desk. In one of the shelves of the desk there’s a newspaper you must take. Go to the closed door on the right and use the newspaper to slide it under the door. Next use the screwdriver to push the key from the door. It will land on the paper, so pull it and gather the key. Walk inside the room. On the left there’s a switch. Use it to turn on an UV lamp. Now use the blank note you picked up earlier to reveal the code (1371). Go back to Section C and use the code…

There’s a map on the wall on the left. Go to the Chemical storage. Kill the dog on your way. Use the left door of the storage from the map, because the other one’s closed. Walk inside. Go forward and you’ll see that something is smashing the door which you came from. It’s that huge worm again. You must be very quick now: run through the first door and use the button on the left. Run right and jump through the green slime. Push another button on the right. Smash the wooden planks with your axe. Put two boxes in the green slime and jump to another side. Smash the wooden column with your axe. You’re safe now. Turn the valve to open the door and walk inside. Save the game using the artifact. In this room you must find six glasses containing some chemical stuff. You’ll also find flares and beef jerky. Use the door to get out of this room.
Find Lake Utuqao on the map and go there. Go through the tunnel until you see two barrels, a backpack and a note. There are painkillers in the backpack. Save the game using the artifact. You must now get to the far other end of the frozen lake. Be careful, because the ice will break if you walk too long on it. Walk slow and stop when the ice starts to break. After you manage to get to the other side you see a frozen hand carrying a crowbar. Use your saw on the hand and pick up the crowbar. Go back through the lake and to the exit.
The last stop is the Incinerator. Find it on the map and go there. Use the crowbar on the door and go inside. Turn left and use the wooden planks to go forward and of course don’t fall down. At the end open the door and go inside. There are painkillers on the right. Pick up a fuse from the desk’s drawer. Pick up the glass from another desk and use it on the little three legged handle on the desk. Turn the valve on the gas tank. Use the lighter to light the gas. From the inventory use the glass with the chemical marked D on the glass on the desk. Then use the chemical marked F. You’ve just created an explosive. Pick it up and go all the way back through the wooden planks. Remember that you’re carrying explosive, so don’t throw it anywhere. After walking down the planks go left and put the explosive on the rocks. Use the fuse on it, light it and stay back! Go down…
The doors on the left and center are closed, so go right. Open the next door and… you found Red. He’s locked in the Incinerator. He will ask you to kill him by pushing the button on the right and setting fire in the Incinerator. There is no other way, you must push the button. After Red burns, look down and get the key. Go back and open the door on the left. This is his room. Look around. Use the artifact to save the game. Use the door on the right and walk inside another room. On the far right move the wardrobe to reveal a power box. Use the screwdriver to open it. Cut the wires with the wire cutter, go back and use the crowbar on the center door…
Pick up the note and go down. Open the door, and turn right. You’re in a long tunnel. You see somebody far away. The rest I leave to you…
