Star Trek: Bridge Commander is a space combat simulation game for the PC. The game allows two different styles of gameplay: storyline mode and quick battle mode. Quick battle mode allows for customized scenarios within a "simulated" environment, allowing the player to pick their allies/enemies, system, etc. With the advent of modding for Star Trek: Bridge Commander, custom missions and even campaigns have been made possible through this engine. The story line begins with the USS Dauntless in orbit of planet, Vesuvi 3. Her captain is piloting a shuttle to a research station orbiting the planet when the star goes supernova, destroying the planet, killing the captain, and severely damaging the Dauntless. After several months of repairs and refits, the Dauntless' first officer becomes her new captain, and after a brief resupply mission to the surviving Vesuvi colonies, an investigation into the star's destruction begins.
