"Ground Control II: Operation Exodus is a 2004 computer game developed by Massive Entertainment and by them classified as a real-time tactics game. It is a sequel to Ground Control, the award winning game of the same genre. Units in the game include various types of tanks, hovercraft, aircraft, and infantry, and are delivered to the battlefield by orbital dropships. However, once in battle, the player is not able to summon reinforcements, so proper troop selection between levels is a key to success. The game features a three-sided conflict. However only two of the factions, the Northern Star Alliance and the Viron Nomads, are actually playable."
