Missions goals include scouting, stealing enemy data and destroying major enemy craft. Mission targets are automatically indicated and locked onto on approach by the Artemis targeting device, and are usually described. Prior to each mission, the player may choose their primary and secondary weapons (other than standard energy-expensive homing torpedoes that come with the craft) from a virtual armory that is added to when research comes up with new weapons (helped along by aforementioned stolen data). Research also comes up with useful devices from time to time, such as one that converts energy to shields, and so on.
