Are you still there?
Licensed replica of one of the cute-but-deadly sentient machine guns that populate the Aperture Science Enrichment Center.
Polystone on a metal armature. Gun arms are permanently deployed; gun shields are magnetically latched and removable. Motion-activated red optic sensor. Sound chip with multiple in-game turret activation, search, disabled, and tipped-over exclamations and phrases.
