Cool thanks,

i collect all 10, but i still dont get the achievement
this game is broken i think

Would a medium game work? Or it has to be long?

found the last one in the boss map near the pond in the opposite side of the vendor on a ramp which is blocked by teeths outside of the map

found all 3 in the shrunk map
1. At the entrance door
2. Under the sofa
3. On the roof at a broken wall

the one ure talking about (Boss map) is on the otherside of the pond near the wall (not the wall with the heads) inside of some tissue

@Lunacy, see my (hopefully understandable) explanation for the third one.

Found the other two on the circus map:

-So the first one is shown in the video (in the center, on one of the corpses at the top impaled onto the fairground attraction)
-stay with me here: if you're standing under the large clown with acid or whatever the fuck is coming out of his face, under the stairs to the right of you is the second one
-Third one is on the lowest ''ring'' of the map, behind a group of boxes and barrels with stars on them (Location is diagonally opposite of the large, fat clown with a flare in his hand)

(part 3/2 xd)

''Boss Map''
-There are two large holes in the ground with tentacles/teeth/whatever in them, one collectible is located somewhere at the bottom of one of them (I had to jump to see it, I don't know if you can find it while walking)
-There's also one near the pond but I have no idea where since I accidentally got this one with a grenade launcher.

(part 2/2)

My explanations might be kinda vague but I'll try my best.

Spider Map
-If you walk up the ramp you see when you spawn and you look at the left part of the stone arch, you can see it inside of the stone ''leg'' in the center.
-One's located behind the first waterfall you see when you pass the large stone pillar with particles around it flying upwards (if you walk from spawn)
-The last one is hidden inside an egg, which is located next to the ramp, which is located next to the large (I hope dead) spider coming out of the wall (near the trader).

Colourless Creepy House (when you're shrunk)
-There's one under the sofa the huge clown is sitting on
