The Flagship
Nicknamed as the SIS — the name which the internal game code uses — the Super Integrated Starship is the flagship flown by The Captain. It is also known as the Vindicator, the default name on the 3DO version of Star Control II, though the name can be changed during the game. The initial structure was created by the automated Precursor base on Unzervalt.
The ship proper is just a framework that Modules can be attached to. The modules have varying effects from increasing the ship's manuverability and speed to storing crew and other supplies. The ship can also be fitted with a host of weapons and energy systems as well as having docking space for up to 12 other smaller ships.
This ship becomes the flagship of the New Alliance of Free Stars and is integral in that group's completion of its ultimate objective.
