KF2 Barmwich Collectibles: All Skull and Medallion Locations
Barmwich is the Halloween-themed Killing Floor 2 map released in autumn 2022, and its collectibles are a lot easier to find than on the previous event map. Only ten glowing skulls are needed for the achievements, but this guide, written by a Steam community author, lists them all together with the six coloured medallions that open the armory. Each spot below comes with a screenshot. For other collectible hunts see the video guide and the achievements page.
The map uses two kinds of items: skulls (the actual collectibles) and medallions (keys to the armory). Both are grouped by area below.
It smells Halloween... and with it, finally a map where collectibles are "easy to find", not like the last map.
You need only ten of these shiny skulls to unlock the achievements but as usual, I'm hunting them. I'm adding also the medaillons needed for accessing the armory.

Not Night Lamps
Medallions
Red: On the corpse in front of the tree on fire
Green: Forge
White: Restaurant
Blue: Inside a tree
Yellow: In a cell
Purple: In the boiler room, under the prison
Once you have all, you can access the armory for... basic weapons.
