How to find black ducks and get to the DOOM level

The first thing we will do is collect black ducks.

Black duck #1

Head to the location marked in the screenshot below:

This is the observatory that you visit in the story of the game. To the right and left of the gate there are two identical towers. Go through the gate, climb onto the armored personnel carrier and jump higher. From the fence, jump onto the tower on the left, if you look towards the city. The first black duck is hidden in this tower.

Black duck #2

Head to the location marked in the screenshot below:

Near the river, on a concrete pier, there are metal supports (to which a cable is usually tied to hold the boat). On one of them stands a black duck.

Black duck #3

Head to the location marked in the screenshot below:

There will be a military base near the river. Jump over the fence and look for an item under the pillars of the destroyed bridge. There is a car there. Open the trunk and take the black duck.

Black duck #4

Head to the location marked in the screenshot below:

Climb the TV tower you visit in the story. To do this, use the elevator. Stand on the metal support that protrudes from the roof, jump down and fly to the floor below in the same building. This office has a note with a clue and a safe. Enter 666 and take the black duck.

Black duck #5

Head to the location marked in the screenshot below:

On the outskirts of the city there will be an area with a yellow zone. There is a black spot near the road in this area. Like oil spilled. There is a black duck there.

How to get to the DOOM level

Collecting five blacks fromcurrent, return to the TV tower and take the elevator not to the roof, but to the basement. Having done this, swim through the flooded tunnel. There will be an open door ahead. Open it and enter the elevator ahead. Go down below to get into the cave.

Arrange five black ducks on the tables, and then connect the generators to the shields so that you get a pentagram. Just connect the generators through one (not the adjacent right one, but the second one clockwise and so on). After that, a shotgun will appear and you can start the challenge with the secret DOOM level.

All secrets on the DOOM level

1. At the very beginning, go to the stairs on the left, where there is one exploding big man and a spitting zombie. To the right of the stairs, there is a green button on a pillar. Click on it. In the first room, a passage will open to the next room, where there is a blueprint in the center. This is the blueprint of Fading Power. By making this item, you will be able to lift enemies into the air. Reference to Star Wars.
2. Keep going through the level. When you find yourself on a path surrounded by green liquid, look for a passage on the left in the corner. Go there and at the end of the path you will find an exploding big man, as well as a box with a blueprint for another weapon. This is the "Sword of the Lady".
3. To the left there is a ladder. Climb up it and look at the end of the narrow corridor for a thank-you letter in which Techland mentions other cool video game developers.
4. Finally, if you start the test, but then?? exit to the main menu, when you return to the game, you will find that the 1993 shotgun from DOOM has ended up in your inventory.

What to do if the elevator in the basement does not work?

This happens if you have already passed the test or just discovered the secret, and then moved to another place. Perhaps in the future the developers will fix the bug, but for now the only option is to stand at the elevator, call a friend for help (select "Online menu" in the menu), and he will open this elevator for you.
