The game has three main modes. Each of these will have will be explained in greater detail later in this book.

• General Exploration
• Hostile Environment Exploration
• Diplomatic Roleplay

In general exploration the characters are in an environment that is not actively trying to kill them. In a hostile environment, they are in an environment that taxes the strength of their spacesuit. Each round could bring disaster.

The game can measure the success of the players in one of two ways (or both): either the collection of Evidence Points, or in getting close to unlocking the Prime Matter.
