You begin in the roof of a mad scientist's lab. How you got there is something of a question, but Caleb seems to have a way of getting into every place he shouldn't.

Fall down into the operating room. You'll see two doors, one up stairs and one on the ground. Go up the stairs and collect the skull key, return to the door on the floor. Go through the door and take the passageway second on your right. Go up the stairs and go into the brain storage. Collect the eye key and go down into the original passage. Proceed to the end of the passage and take a right.

Feel free to step into the dining room. The guys who live here don't like company much though, so you'll have to silence them. Proceed through the electricity found on the left of the room. Continue down the passage and you'll find a room with innocents and a gill beast behind bars. Go through the door on the opposite side of the room, the seal of Tchernobog will be behind it.

When you begin the level, proceed through the passage until you find the skull door on your right. Go through the doors up ahead of you. The innocent is the ass carrying the key. Kill him.

When you enter the skull key door, go up the stairs and when you have the choice to go up or down the stairs, go up. Take note of the eye key door on your far left. Go up the stairs and take a left at the top. Climb the stairs and you'll find a peaceful sitting spot. Kill the cultist and take the eye key. Go through the eye key door and continue straight until you find a pool of water. Dive in and swim your way to the seal of Tchernobog.

You begin in water, so there's no time to waste! Swim forward and surface. Turn and you'll see a house. Enter the house and go through the hole found in the wall inside. Fall onto the questionable liquid found below, hit the switch and exit the room. You'll see a passage ahead and a bit to the left of you. Go into that passage and turn left. Walk to the end of it. There will be a passage to your right and a slope to your left. Go up the slope and take note of the bars found on your right. Now go back down and take the passage in front of you. Follow the small river and take a left when the passage shows itself.

Enter the room and go up the stairs. Take a right when you reach the top and continue moving until you have to take a left turn. You'll see a river on the opposite side of a large room. Go with the flow.

You'll find yourself in water. Swim until you can't swim any further. There will be a TNT barrel underwater. Blow it up and then jump out of the water using the platform you created. Jump into the small canal and push the button you find there.

The button opens a door underwater. Swim through it and you'll surface in a very watery area. Turn right at the first opportunity. Follow the passage and you'll end up near where you started. Go to the bars I pointed out earlier at the top of the slope, they will be open. Go through, turn right and go as far as you can. Then turn left, you'll enter an outside area. Go right toward the large water tower. Jump inside and walk to the other side of the valley. Go through the cave area and you'll find the seal of Tchernobog.

You begin in dark forest. Go into the building you find up ahead and to the left of you. There is a lift inside. Go up the lift and exit the building through the window. Go right and you'll find another building entrance. Go through the door and go up the stairs on your right. Move through the building. It it pretty simple. Stick to the grassy path and keep moving. Eventually you'll find another wooden building. Go in the door found on the left, you'll find the moon key.

Eventually, if you stick to the path, you'll find an outhouse. Open the moon key door and fall down the toilet. Delightful! When you fall into the water, move into the metallic passage and then take a left. When you reach the end of the passage take a right. Go to the end of the passage and take a left. Around the corner will be a switch. Hit the switch and the bars will open. Surface and you'll see a ledge. Climb onto it and the seal of Tchernobog will stand before you.

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

You begin in an evil, fiery place. The smell of death and decay surrounds you and you can hear monks humming in the distance. An ominous setting.

When you begin, proceed to the floating platforms on the lava. Go forward and take a left and go through the dark passage ahead. When you reach the end of the passage take a right. Climb the rock surface and eventually you'll reach a spot where you have to jump onto a brick surface. Jump across until you reach the next rock surface. The path is actually very straight from then on. You'll find the skull key in a cave, if you stick to the path and eventually you'll find the skull key door, passing through it, you'll find a brick structure with skeletons hanging before it. Tchernobog's presence can be felt about this place. The seal of Tchernobog is through the door.

There are tons of shortcuts on this level if you use jumping boots, they are easy to spot.

From the start you can tell that this is going to be one dangerous mission. It is very scary in appearance, but is in fact, not a very difficult level.

When you begin, cross that ominous bridge and go right. Push the skull button on the right to open the gate. I would recommend drawing that queen spider to those clouds and laughing as she falls to her doom. Go through the gate and continue along the path. Eventually you'll find a skull key door. Go through the door at the end of the passage. On the opposite side of this room there are two skull switches. Activate them and the center piece will lower the skull key. This is one crispy key though, as a trap awaits when you pick it up! The rest of the level is incredibly simple.You basically can't go wrong unless you turn backwards.

Just a note for when you fight the queen spiders in that room with the spider key - I think they put those there to trick you into wasting your ammo. It's really a waste of time killing them.

This mission takes place inside a body. This level is quite easy but the environment can make it seem a bit overwhelming at times.

When you begin. You'll see an elevator-like object ahead of you, pulsing up and down. Move onto the elevator and proceed down it. Go down the passage you find and take the first left possible. When you move down the passage, take a right There will be a few platforms over a body of ... water. Jump along them and fire at the skull switch at the end. Be patient and eventually the poles will open up ahead of you. Go through this newly created passage and continue until you find a pool of liquid.

There is a passage with gill beasts in. Go down the passage and push the button at the end of it. Go up the stairs and then enter the body of liquid. There will be a gap leading into the next chamber underwater. Go through the doorway found on your left underwater and surface there. There is a skull switch nearby. Press it and go through a nearby passage, on the opposite side of the room.

In the next room there will be pummeling objects. Avoid them and make your way to the opposite side of the room. There will be a passage in the wall, climb into the passage. At the end of the passage will be the seal of Tchernobog.

When you begin, move into the building and fire at the skull on the wall. You'll hear Tchernobog laugh and a wall to your left will open. Go through there and kill the stone gargoyle inside.

Upon the stone gargoyle's death, a doorway will open on the opposite side of the chamber. Go through there and fight the queen spider. When the queen spider dies two walls will open.

Go through the new passage and kill Cerberus. Then proceed into Tchernobog's throne room and push the obelisk in the center. It will lower, as will Tchernobog's throne and Tchernobog will come out to face you.

Tchernobog isn't as tough as you'd like him to be. Napalm launcher and conventional weapons work well on him.

Kill Tchernobog to finish the level complete the episode (and the original Blood!).

You begin with annoying, happy music in your ears. Proceed forward and enter the room with the pool in the middle. Exit the room, stage left. Go through the passage and you'll see the entrance to a large shop to your right. Enter the shop and take a left turn. Continue through the store and you'll find an escalator. Go up the escalator and you'll find a stone gargoyle. Kill the stone gargoyle and take his key. You'll see a ledge up ahead, go to it and take a right. Go down the passage you find on the right and then take a left at the end of it. You should be assaulted by a lot of zombie forces. At the end of the passage you'll find the skull key door.

Go through the door and move up the steps. Take note of the grate to your top left. Go to the end of the passage and take a right turn. In the room you find at the end of the passage there should be a button. Press it and break through the grate I pointed out earlier.

Pass through the grate and you'll end up in a storage room. There will be a hole in the ceiling, make your way towards that hole and jump through it. You'll find the seal of Tchernobog up there.
