Gunner cage

The Gunner cage is a constructible item added to Fallout 4 by the Wasteland Workshop add-on.

Characteristics
A medium-sized cage, the Gunner cage will, when powered, capture and hold Gunners and their variants. A predominantly steel enclosure, the Gunner cage promises free caps, ammo, and guns to lure unsuspecting Gunners into the trap.

Upon release, the Gunner occupant immediately becomes hostile to the player character and any settlers.
