- Enrichment Sphere 1 is made out of two enrichment spheres. The first one is dark, most of the props have no textures and puzzles aren't existent, and the second one is the one playable in-game. The player gets teleported from the first one to the second one during the activation of lights. A similar solution is used in Chapter 4, Test Chamber 21.
