Zero Sum Game's StarDrive, an action strategy game where players build a space empire, is now available for pre-order on Steam. Those who pre-order the game will receive a 17 percent discount and be given immediate access to the game's beta.

StarDrive is a "4x strategy game," a subgenre of strategy games where players control an empire and explore, expand, exploit and exterminate. The game plays out in real-time and allows players to choose from eight alien races, or design their own. Players can also colonize different planets and build them into specialized centers of trade or industry. Space bears are among the races that exist in the game.

StarDrive will be available on Steam for Windows PC on April 19. The pre-order offer ends on the same day.
