The Void Ray is a new unit to Starcraft 2. It functions as a aerial siege weapon, dealing higher damage the longer it fires on a target. The Void Ray is available from the Stargate, yet has an upgrade that increases movement speed and acceleration at the Fleet Beacon. This unit is great to use in combination with the Phoenix, as it can immobilize a target with Graviton Beam, and the Void Ray can unleash its full powerful attack on the target.
