Expansion Series - includes a new Flagship of the Titan class. This ship is massive but slow, only a single Titan ship can be in-play at one time. There is also a Capitalship known as a Dreadnought, a very large and powerful Capitalship that once at level six or beyond can be upgraded into a Super-Dreadnought. Dreadnought's are automatically and repeatedly built by a special factory ... only one unique factory is made available for each player at the start of the game. Also included in the expansion series are more aggressive Pirates capable of colonizing. Finally beware of dangerous asteroids which fill the gravity well of various planets, they can severely damage fleets through collisions.
