KF2 Elysium: Snowglobe Collectibles, Roses and Books
Elysium is a Killing Floor 2 Christmas-event map made of several themed arenas. It has no collectible achievement, but it hides snowglobes that are fun to hunt, plus roses and books needed to unlock two hidden locations (Botanica and the Loremaster Sanctum). The author warns the list may be incomplete, and a commenter later pointed out one missing snowglobe in the main arena, which is included here. Locations are small and often busy with zeds, so expect to look quickly. Related: Elysium lore and arenas and the overview of KF2 collectible maps.
Roses: the Farm
Three roses lie in the Farm location: in a toilet, in front of a doghouse and near the cave. Carry them to the pots in the arena to unlock Botanica.

Books: Egyptian Ruins
Four books: near the spawn, in the left pool, in the cave and at the top of the stairs. Place them on the altars in the arena; a wall lowers to reveal a lever, and pulling it unlocks the second hidden location (Loremaster Sanctum).
