Combat Two is the sequel to Combat, but never saw the light of day like so many other Atari prototypes.
Retrodesign decided to release Combat Two to the public in grand style by creating an Atari style box, manual, and label for the game. 200 copies of the game were made available at Classic Gaming Expo 2001 and were sold for $30 each. An additional 50 copies were made available to collectors outside of the United States.
