The Nova Box adds new modules, and new features to Startropolis including Secret Missions, Unique Player Abilities, and Advanced Modules Rules.

The Nova Box adds SIX new types of modules! Each operates differently from the six core game module types. This expansion also comes with advanced Modules cards to replace basic module cards, rendering each color of each module unique!

You can also now play with Mission Cards that provide new secret missions that give you extra revenue for the game end.

And finally, with the Nova box each player can be a different Alien Faction, each with its own unique permanent ability, as well as a once per game ability!
