KF2 Monster Ball Collectibles: Skeleton Achievement (10)

Monster Ball is the Halloween map for Killing Floor 2, and it hides ten collectibles that unlock a map achievement. This walkthrough, translated and paraphrased from a Spanish Steam guide, shows them in the order you reach them while moving from the spawn through the castle and down to Hans' disco. Other map routes are collected in the collectibles master guide.

Collectible 1

At the spawn, turn to the left. You will see a torch; the first collectible lies in the grass beneath it.
