Pinnacle Highrise is an unmarked location in Fallout 4.
The interior of the skyscraper has three accessible floors:
- Ground floor is a confusing maze of corridors, with Gunners encroaching on the super mutant turf.
- The middle one (11th floor), is mostly a skybridge with adjoining storage rooms and plenty of Gunners engaged in a running battle with the super mutants.
- The upper one (21st floor), with the exit to the highway, contains a small office with super mutants and several gunner corpses.
This highrise is just west of Postal Square, and is accessed with a fire escape on the western side of the building. The entrance hallway on the fifth story leads to a two-tiered reception room with an elevator in the southeast corner. This elevator leads up to the eleventh floor, which contains a long hallway that is the site of a super mutant-Gunner gunfight. Another elevator at the end of this hallway ascends to the the twenty-first floor, where a door leads to the fallen skybridge.
- Despite the fact that this location consists of two buildings, both local maps are marked "Ruined Skyscraper."
Pinnacle Highrise appears only in Fallout 4.
