You begin in the fairly deserted streets of a city. The cool winds add to the ominous feel of the place.

Go around the corner on your left, there will be a metal door on your left. Open the door and you'll see the spider key door in front of you. If you go down the passage to the right you'll find an art gallery. There are fanatics in the gallery and one is carrying the spider key. Terminate the fanatic and take his key. Go through the spider key door. Continue up the stairs and there will be a fire hydrant on the wall. Blow up the fire hydrant (preferably not with your pitchfork!) and you'll have blown a hole in the side of the building. You must jump into the next building. Get used to jumping between the buildings as you're going to have to do this a few times. Continue up the stairs in the next building and follow the path until you find a greyish room. Around the corner to the right will be the moon key. Once you pick up the moon key air strikes commence on the city. A hole will be blown in one of the buildings. Go through the hole and you'll find the moon key door to your left. Inside the room you'll find the fire key.

The fire key door is the entrance to the central building. Go through the door and go right. Jump over the overturned desk.

On the opposite side of the room you'll see two doors. Go in the left door and kill the manager. Take the key and go through the door on the right. Go up the spiral staircase. Now, if you look through the window on your right when you exit the spiral staircase, you'll see a crack in the building. Blow up the crack with explosives and then continue left. You'll see the skull key door on the opposite end of the room. Open the door, take the dagger key and go through the hole you blew in the other building. The dagger key door will be there. Go through the door and the seal of Tchernobog will be on the far right wall.

When you begin, proceed into the next room and use dynamite on the crack next to the grandfather clock. It is quite hard to see. When you go through the hole you blow in the wall, open the door on the right. Go left and eventually you'll see a hole in the wall that leads to 'Feinman meats' go through the large metal door on the left. The door on the left in the room leads to the second floor. Go through the door on the right and go to the right end of the courtyard and you'll find a gold metal door, go through it and you'll find the skull key.

Make your way back to the second floor of the building, the skull key door will be right in your face. Open the skull key door and you'll enter the room with the rotating chickens. There is a button on the opposite side of the room, at the bottom. Go and press the button and another button will appear near the rotating chickens. Push the button and stairs will form. Go up the stairs and another button will be there. Push the button and exit the room. On the other side of the second floor of the building, there will be a button, push it and then to your right a door will open. Exit through this door. You'll eventually find a water tower. Go into the window on the opposite side of the area. Kill the fanatic and take his key. Go through the door near the water tower and blow up the barrels at the end of the passage. A passage will present itself. Go through the passage and a nearby building will get bombed. Jump on top of the ruins and you'll find a ledge with a spinning fan on the one side. Break the fan and fall down the ventilation shaft. Stick to the right wall in this building and eventually you'll find the moon key door, that needs the key you took from the fanatic.

Go through the gate and hit the switches on the right wall until red lights light up the passage. Then proceed and a giant safe will open in the next room. If you go through the well-lit passage, you'll see two dials on your left, but don't strain your brain on these. Just turn the left dial twice and then go into the area with all the cabinets.

One of the cabinets will be destroyed, leading to a dirty passage. To the right of this passage will be the seal of Tchernobog.

This level is very straightforward.

When you begin, proceed forward until you find the pool. Swim through the underwater passage and you'll find two valves. Turn the two valves and the underwater passage will open further. Go through the passage and surface at the end of the water. Continue until you find a small river of water. Follow the water and turn left at your first chance. Continue along the passage and eventually there will be a small window with water trickling out. Jump through the window and fall into the water. Swim through the water and eventually, when you surface the skull key will be on the opposite end of the room. The rest of the level is very simple. Just stick to the path and keep moving forward. Eventually you'll find a room on the opposite side of the room with the eye key door. In the room there is a button which opens the large, round structure behind you in a very cool fashion.

The eye key will be revealed. Go through the eye key door. The rest of the level is simple.

You begin outside a hospital. There are two glass doors to enter the hospital. Smash the one on the left and go through it. You will come out in the emergency room. Go through the doors on the opposite end of the emergency room. You will come out into the main waiting room of the hospital. Go to the opposite side of the room and jump over the counter which has a sign above that reads : "Hospital information and admission". There will be a bloated butcher. Kill him and take the eye key. Go up the slopes in the main room and go through the eye key door. Continue down until you reach another waiting room. There will be a path just to the right of the counter. Go down this path.

To your right you'll see a sign that says : "Assisted suicide ward". Go in here and collect the fire key. Go back to the waiting room and go the left way. If you go down the passage you'll find the fire key door. Go through there and go left. You'll find a small chapel like structure.

Inside the chapel is the skull key. Collect the key and return to the waiting room. Go through the right passage and turn left. At the end of the passage will be the skull key door. This is in fact an elevator. Go up the elevator and go in the door to your left. The dagger key will be here. Collect the dagger key and pass through the morgue, preferably quickly. Go out the opposite door and on your right will be the gate to the dagger key area. Open the gate and go down the left passage when you find the fork. There will be a switch. Pull the switch and then go down the right passage of the fork. Enjoy watching those damn innocents get flamed.

Down the right passage is the seal of Tchernobog.

This level has a path to reach the secret level! Read the secret guide to find out where it is!

You begin in a crude factory-like setting with a button before you.

Firstly, you'll want to go through the door on your right. If you turn right and go around the corner, a stairway will be found. Go up the stairs and you'll enter a room with conveyor belts. One of the conveyor belts has pummeling machines on it. You have to go through this conveyor belt. When you reach the end, turn right and walk along the metal grates. You'll find a button. Press it and then return to the button you found at the beginning of the level and push it. Then go back up the stairs and go through the metal door found on your left. Once the room has scanned and found you to be expendible, exit through the other side. You'll see two white doors on the other side of the room. Pass through them and hit the switch inside. The room will rotate and open on the other side. Look up at the room with the fanatics. There is a button on either wall in the room. Go and push the buttons and then go to the tubes found on the other side of the room. Pull the switch near the tubes and once the red liquid (blood?) has filled the tubes you'll be able to enter a door found through the right passage.

Through the passage you'll find a switch. Push it and the floor will lower behind you, revealing a button. Push it and the door on the opposite side of the room will open. Go through there and you'll find a fairly dark room. The opposite side holds a button. Go push it and then a hole will open in the tube found in front of you. Drop through the hole and move through the lava. Eventually you'll find a large room with cultists on a metal ledge. Go to the room found on the right of them. There will be three red lines with three switches on the wall. Push the buttons until the red lines are horizontally situated. They will lower and the skull key will appear in the wall. Take the key and go along the metal ledge. You'll find a storage room on your right. Turn left as you enter the storage room and pass through the door. The skull key door will be before you. Open the door and activate the lift found through there. Walk along and you'll find another skull key door. Open it and the seal of Tchernobog will be in front of you.

This level contains a lot of shortcuts. Just use your jump boots.

You begin in a mechanical chamber alongside a flow of water.

Go into the next room when you start. Go to the right and cross the bridge. The bridge will explode and rocks will come tumbling down. Jump onto the platform that has presented itself. Stick to the path and you'll eventually enter a room with a button the table. Buttons, buttons and more buttons around here. First, push the button the table. A door to your right will open. Go into the little passage and walk to the end of it. A button will be up there. Push the button and the nearby platform will lower to present a button. Push the button and the door on the opposite side of the chamber will open. At the end of the passage will be a button. Push the button and a platform will lower and you'll find a... guess what?... a button. Push the button and the central panel will lower.

In the next room there are two buttons, push them both to open the door. If you enter the room, on your far right will be a lever. Pull the lever and the room will light up. Push the button against the wall and you'll be able to enter the lift. Go up the lift and cross the bridge. When you cross the bridge, go right and you'll find stairs. At the top of the stairs take a right turn and enter the large generator room. Enter the generator room and push both computer terminals you find between the large turbines, a lift on the opposite wall will open. Go up and collect the moon key, found at the end of the bridge. Go back the way you came in. Follow the river and jump onto the ledge on the right. There will be a moon key door on your right. Go through the door and on your right will be a puzzle. Pull the switch and the arrow will turn. There are two dials. There are three separate doors ahead of you, represented by the lines on the wall. A blue line represents an open door and a red line a closed one. If you can't solve it, here is the answer, follow these instructions:

- Hit the main switch to reveal the dial on the right side.
- Turn the right side dial twice, the middle red line is now blue.
- Hit the main switch twice to reveal the dial on the left side.
- Turn the left side dial once, the first line is now blue.
- Hit the main switch twice to reveal the dial on the right side.
- Turn the right side dial once, the third line is now blue.
- Hit the main switch and the puzzle is complete.

In the next room is a large central post. Go into the side control chamber and hit the switch. The post will rotate. Jump on the new ledge and push the back of the central post. The ledge will rotate so you can enter the door. Go through the door and on the far left of the room will be an elevator. Go up the elevator and go down the left passage. You'll find yourself in a storage area. Go through the storage area and keep going. Eventually you'll find an elevator. Go up it and you'll find yourself on a dam wall. Pick up the fire key and dive into the water. You'll see some TNT barrels at the base of the wall. Blow up the barrels and the water will reach a state of equilibrium on either side of the wall. You can now reach the dirt ledge on the other side of the water. Pass through the passage and push the obelisk. The door will open, step into the flames and the mission is complete.

You begin in a flaming, rocky area. Proceed forward until you pass through the metal doors. There are five skull switches to be found in this area. Push all five and the rocks in the central arena will be destroyed, revealing Cerberus.

Cerberus is very powerful, avoid his fireball attack at all costs. Tesla and voodoo doll work well on him. Resort to napalm launcher if you have to.

Kill Cerberus to win the level and complete the episode.

You begin in an eerie passage, leading to darkness.

Go to the opposite side of the room you start off in. Open the door and go into the main room with the bricks. Go through the passage found on the right and keep moving forward. Eventually you'll find the eye key door. Take note of it.

Go down the passage on the left and enter the catacombs. Go through the wooden doors and continue until you find earth passages with torches on stands. Go down the passage and eventually you'll see two torches. One in front of you and one off to the right. Go to the torch on the right and continue straight down that passage. Eventually when you go around the corners you'll find the skull key on your right. Return to the area where you can see the two torches at once. Stick to the left wall and eventually you'll find a pool area.

Go up either of the two staircases found in the pool area. Proceed to the far side of the passage and continue through the passage. An ambush will be waiting. One of the compartments that the enemies come out of will contain a button. Press it and then exit the room. A panel on the far side of the golden brick room will have opened to reveal a button. Push the button and the nearby wall will raise to reveal a room. Go up the stairs and go through the passage.

Eventually you'll find the eye key. You will be assaulted by zombies when you get the key. Contain their pathetic resistance and go back to the eye key door you saw in the beginning of the level. A fairly mechanical room will be through the door. Against the wall there will be a button. Push the button and another button will present itself in a very mechanical fashion. Push the button and the nearby wall will raise to show the seal of Tchernobog.
