Solitary

"The security spire's damaged interior only hints at the terrifying power of its previous inhabitant."

- Halo Waypoint - Halo Bulletin 11/9/11

Solitary is a multiplayer map included in Halo: Combat Evolved Anniversary for Halo: Reach. It is a remake of Prisoner from Halo: Combat Evolved with several alterations to layout such as new gravity lifts and walkways on the backsides of the map. The game space is placed inside a recently outbreaked Forerunner prison in a big rotating structure in a snowy region.

Trivia

 * If you look out the window on the side of the map where the Sniper Rifle spawns you can see other large rotating structures, possibly other prison complexes.
 * The structures are built atop very tall spires, making escape highly unlikely.
 * There is a large hole in one of the walls of the prison alluding to the fact that the former occupant(s) may have escaped, despite the large fall that would be needed to survive and escape.
 * In the room with the blue stasis tanks there is a Spartan doll.
