Supernova is the first expansion for Armada 2526 and gives you more to explore, more to exploit, two new races to exterminate and lets you challenge your friends over a local area network, or by email. The exploration side of the game has been greatly enhanced with new types of stars and planets and a wide variety of special characteristics that a system may possess. There’s a new trade system that lets you build up a trading network, a system for espionage and special operations, new technologies to research and lots of new units types.
