Break the glass above the door using alt fire. There’s you first 0-1 secret

In the third room with glass panels and a large fan, climb up the pipes. There’s you second 0-1 secret
[/previewimg]

Right after the last room. Keep climbing up the wall to find the secret. There’s you third 0-1 secret

This secret is in a room with a lot of pipes. You can see it under the ceiling if you look up. There’s you forth 0-1 secret

This secret is in the room where the game teaches you groud slam. Break the vent and take the secret.There’s you fifth and last 0-1 secret.

This challenge is so simple that it’s easy to do by accident. Just make a lot of enemies crowd on one glass pane and blow it up.

In the first room with the statue, climb the pipes.

In a room with big pipes pouring blood.

After passing Crushers, turn around to see the ventilation. Break it and go through the only open door
Good luck 🙂
IMPORTANT: YOU ONLY HAVE TO COLLECT EACH SECRET ONLY ONCE, MEANING THAT IF YOU DIE ON THE WAY BACK, YOUR SECRET WILL STILL BE MARKED AS COLLECTED

After passing the Crushers, go through the left door
Break the Ventilation and go through.
(Sorry, picked that secret up by accident)

Go through the blood waterfall in the last room

From the 4th secret, turn to the right and crawl along the ventilation.
At the fork, turn right. Break the vent and go into the room with the boss.
Defeat the boss to complete the challenge

To find the Secret Mission you first need to find the skull. It is located in the open vent above the statue before the room with crushers.
Pick up the skull (on the F button if you don’t already know) and go to the room just before the 4th secret

Put the skull on the pedestal (on the F button) and one of the walls will open, revealing the way to the secret mission

This secret is in the room where you are introduced to the new enemy. Break the glass ceiling and turn around to find the secret

This secret is in the room which entrance you blew up with your shotgun. Right above the archway

The last secret is in the room in front of the boss (second encounter). Turn around and find the wall with a crack. Break it by using the alternate shotgun fire

You won’t be able to simply complete the challenge, because at a certain point the game blocks the door and requires you to kill the enemies. In fact, in the first room there is a not quite obvious shortcut. You need to break the glass ceiling and use any technique to get up, such as slam storage. After you get up there just defeat the boss and the challenge is over.

In the first room on the right column under the ceiling.

In the room with the spinning killer thing. break the glass on the right and enter the room. Note: you will have to kill 🗿x2 before you can get your secret.

Under the glass in the last room

There are several ways to complete the challenge in this level, but I recommend completing the level as normal, killing all the enemies but not breaking the glass in the last room. After passing, go back to the beginning, try to rotate your camera exactly in the center and just Slide until the end of the level

Cerberus attacks will damage them if you dodge in time. The easiest way to complete the challenge is to deal damage, but leave the Cerberus with very little HP, then just dodge until they kill themselves

This ♥♥♥♥ is actually unreasonably scary, so prepare to ♥♥♥♥ yourself.
(by the way in the game files on this level the challenge is “don’t ♥♥♥♥ yourself”, but don’t worry you can’t complete it)
and before me locked_dream has already made the most detailed guide to this level, you can read it here.
The level is very dark, you will need a map.
As soon as you take the skull Something Wicked will wake up. Don’t waste a second and use your bunny hop skills to move along the path marked on the map by the blue line. Put the skull on the pedestal, while Something Wicked should disappear for a while until you take the red skull. When you do, bunny hop along the red line on the map and immediately place the skull on the pedestal.
Tip: Use F to temporarily increase the skull’s lighting power.

On this layer, in addition to the usual secrets and challenges, there is also an Alternate Revolver that you can get if you press 4 tiles on each level in limbo.

Here’s my crappy map that will (probably) help you with the secrets.

The first secret is to the right of the red pedestal. there will be nothing in the room but a tower, climb it and get your secret.

The second secret is above the fallen column in the room with the red pedestal. You’ll have to go through the wall

Behind the waterfall in the room where you first meet the drones

Behind the painting in the room where you are introduced to the alternate minigun attack

Under the ceiling in the room before the final battle.

To find the secret mission toss a revolver marksman coin into the fountain at the start of the level.
To complete the chellege do it in 10 seconds, it’s simple

As I mentioned earlier on the Limbo layer, it is possible to get an alternate revolver. The first tile is on the roof of the last room, just break the glass and use the alternate shotgun fire to jump

The first secret is in the room where you fight for the first time on this level. Go to any side passage
and take the secret under the ceiling.

The second secret is in the section with the flamethrowers.

The third secret is in the room with the blue skull. Go to the passage under the stairs and get the secret

The fourth secret is behind this door
There’s not much to explain

The fifth secret is under the stairs again. Careful: as soon as you collect it, the Cerberus wakes up.

In the cosnote with the fourth secret, turn around to find a cracked wall.
Break it, go further and find another cracked wall. Behind it will be a small “village” where you will meet Cancerous Rodent. Defeat him and go back to meet the Very Cancerous Rodent! After defeating him, the grate will open and you will be able to press the button.

First secret in the first room, break the glass and get to the roof.

The second secret is in the first room with the red skull. You need to slide on the slope.

The third secret is easy to get if you have already taken the red skull, go through the hole in the wall and drop down

The fourth secret is behind the stream near the blue skull.

The fifth secret under the stairs in the blue skull’s path.

How convenient, all in one place!
Put both skulls on their pedestals and the picture will take you to the Secret encounter.
Defeat the Swords machines to complete the chellege and unlock the slab.

In the room to the right in the path of the blue skull, you can punch through the ceiling and get out.
On the roof of the room there will be a very scary soap that everyone is afraid of. Just pick it up on F and hit any enemy to kill it instantly. Soap is only enough for one enemy, so choose wisely who you will kill with it.

The last slab and alternitve revolver is at that level. Turn right in the main hallway.
You will see a large door and the last slab in front of it.
Press slab to open the door and take the revolver.

The window above the pedestals is glass (what a shame) break it with any weapon and you’re in the room with the boss.

This level is a major disappointment if you went into the game to mindlessly kill anything that moves.
Either way, here are all the solutions:

Break the wall near the ramp

Under the first bridge

Good luck
but seriously, use rocket surfing or other movement technique.

Under the end of the first bridge

To the left of the exit of the second tower

To complete the challenge you need to go outside to the first secret and fly to the end of the level using rocket surfing

In the window above the cerberus. Break the glass to get through

At the place where the soldiers are on your left. Go to them and go downs to get secret

There are no secrets here, just learn the movement techniques and speedrun the level

Slide under the wall by the red pedestal.

Slide under the bridge

In a room with a lot of crushers. To the left of the entrance under the ceiling

Above the bridge

In the crusher room by the left wall

The challenge cannot simply be completed, as the final door is behind the waterfall. Don’t worry, this guide will tell you how to complete this challenge.
You can drain all the water in the level and also disable the dangerous traps if you break three breakers. All the breakers can be found near the secrets.
After defeating all the breakers go to the exit of your choice: vector or normal.

To get to the secret mission you need to drain all the water on the level and go through the door behind the volopad
