The Goblin combines exotic engineering with Covenant manufacturing technology and a user interface designed specifically for an Unggoy. The vehicle's cockpit is equipped with an energy shield while the main body of the Goblin is made of thick armor plates. The vehicle has a needle cannon mounted on its right arm and a Shardstorm launcher, which releases huge volleys of needles at once, mounted on its back. The Goblin can also perform close-quarter combat maneuvers, using its fist and legs to fight. The legs can produce an EMP when stomping, and its fist doubles as a grenade launcher that fires plasma grenades.
A second variant of the Goblin, known as the Beam Goblin, has also been produced. The Beam Goblin has different armaments than the standard Goblin. Instead of the Heavy Needler, it sports focus beam similar to a Scarab's. In addition, it fires tracking plasma bolts that produce an EMP effect on detonation, rather than a rear-mounted Shardstorm launcher.
