The Cobra Terror Drome was the largest of the Cobra playsets produced for the 3 3/4" line.
Acting as a portable, temporary headquarters for Cobra, the Terror Drome featured various communication arrays for soldiers, refueling stations for vehicles, and a cell for holding G.I.Joe prisoners.
The playset also featured a 'secret launch mechanism that activate silo doors, elevator and raises the Firebat for launch.' The Firebat was a one-man vehicle used for short-range attacks or fast escapes from G.I.Joe. This Firebat was never sold by itself, but is now available in the 25th Anniversary line of G.I.Joe vehicles.
The Terror Drome came with blueprints/instructions for assembly, sticker sheet(s), multiple small accessories, and A.V.A.C. figure with filecard.
