This expansion allows a player to use a radioactive core module in "Startropolis" instead of the ordinary one included in the base game. It comes with a glow-in-the-dark radioactive core module component and a rules card describing how using it affects gameplay. Essentially, with a radioactive core, adjacent modules start with enhanced abilities but burn out during the course of the game.
A spaceship turn marker component is also included with the expansion.
