Interstellar Marines has sold over 100,000 copies since it launched in July 2013 on Steam Early Access, developer Zero Point Software announced this week. The sci-fi game has generated "more than $1.5 million in revenue" for the studio. Still in "heavy development," the tactical FPS will also receive an update on September 18 that adds cooperative multiplayer to the game.
Zero Point Software first revealed Interstellar Marines in 2006, and the game received multiple "it's still alive" reassurances over the years. Players can pick up the game on PC, Mac or Linux via Steam for $18.99, which grants access to both the Early Access version of the game and its upcoming expansions and updates, such as the "Project Co-Op" one scheduled for next month. The developer will showcase its spacey shooter at PAX Prime in Seattle this weekend at Alienware's booth (#1246).
