KF2 Prison: Collectible Locations by Area (Screenshots)
On Prison the necklaces hide in cells, corners and on railings, cameras and light poles, which makes the hunt both fun and easy to botch. This area-by-area route has a screenshot for every location, from the courtyard through the cells, hospital and main hub to the mess and showers. For an alternative write-up of the same map see KF2 Prison collectibles. See also the overview of KF2 collectible maps.
