Darkstar One is an action-packed game that offers enormous freedom of choice. The game is in a vast, simulated universe with many unique races and spaceships. You play as Kayron Jarvis, a young adventurer who inherits a powerful spaceship, the Darkstar One, from his father. As you progress through the game, you will explore new solar systems, encounter new races, and upgrade your ship with artifacts and better equipment.

The game features an elaborate story related to more than fifty minutes of video sequences. You can configure and upgrade your ship any way you choose, whether to build a fast attack ship with many light weapons or a near-invincible cruiser with heavy weaponry. Darkstar One offers over two hundred different weapons, shields, and equipment items, including rockets, torpedoes, and mines with special tactical uses. You can even acquire weapons from other races, each featuring unique functions that require different battle tactics. Embark on special missions, explore canyons, or even underground on unknown worlds. Darkstar One offers a fantastic amount of freedom of choice, allowing you to play as the "good" or the "bad" guy and take advantage of political disputes.
