Diorama Museum

The wiki's dedicated page for this map is titled simply "Museum" (its Diorama charm is called "Diorama Museum"). It's described as a relatively large, Medium-difficulty, two-floor map. The lower floor has purple fossils with ropes marking an out-of-bounds area behind them, and a big staircase leading up to the second floor. A second route upstairs runs through two artifact-filled hallways on the first floor, each ending in a ladder that can be knocked down but still allows climbing to the second floor.
