Interstellar Marines, the sci-fi FPS title from developer Zero Point Software, has surpassed the 100,000 copies sold mark through their Steam Early Access program.
According to the devs, the game has earned them "more than $1.5 million in revenue," a feat that many indie developers only dream of. Still in "heavy development," the tactical FPS will soon be adding cooperative multiplayer to celebrate the milestone, come an update on September 18th.
Zero Point Software revealed the game way back in 2006, receiving a number of "we are still alive" assurances from the developer until its release last year on Steam Early Access. Those eager can pick it up on Steam
for $18.99, which include both Early Access and its upcoming expansions and updates.
