Overview
This guide will show you how to get all the secrets on every level.Some of them are very tricky and requires lots of jumping and bunny hopping.Feel free to comment if I missed something.Additional thanks to pkrus.ru for the screenshots.
Cemetery (C1L1)
As soon as you passed the checkpoint run to the barrel and push it away so the roof wouldn’t crush it. Once you finished with the enemies take the barrel to the next checkpoint and place it behind a construction.
Atrium Complex (C1L2)
Right before the first checkpoint take right to the secret room.
Use a Painkiller weapon to break the big chest.
After opening the exit portal go back to room where the burning barrel were rolled at you.
Same as #3 but in the first open area.
Catacombs (C1L3)
Follow the jumping route on the screenshot.
One of the pillars have a rope on the side.
Climb up and bunny hop off the roots to the holy item.
Get the dynamite box and push it to the screenshot 2 location.
Cathedral (C1L4)
Bunny hop all the way.
This area opens after completing a level (getting an exit portal).
To go back look for the stairs on the wall.
Enclave (C1L5)
No secrets here.
Just kill the boss and collect all ammo.
Prison (C2L1)
This one requires a little bit of your patience.
Opera House (C2L2)
Bunny hop off the ledge.
Here you can bunny hop off the pillar or use any breakables.
Another practice in bunny hopping. Make sure to clear the area.
Asylum (C2L3)
Climb up and bunny hop around the window.
This one is next to the first checkpoint.
This room will open only after completing the level.
Snowy Bridge (C2L4)
Next to the first checkpoint at the end of a pipe.
On the other side of a same pipe. It will open after completing the level.
Climb up the first ladder and then bunny hop around.
Stick to a wall under the stairs.
After a warehouse climb down the ladder.
Town (C2L5)
This is a tricky one. You can use Painkiller alt. attack on a cart to get up or place it the way it shown on the 3rd screenshot.
Stand on the cart and use Painkiller alt. attack to reach the second floor.
Another shenanigans with a cart.

Docks (C5L2)
