 Sinistar : Unleashed is a 1999 action space shooter video game for Microsoft Windows . It was designed by Marc Michalik and Walter Wright and developed at GameFX , a small studio composed of former members of Looking Glass Studios . Originally titled Out of the Void , development of the project began in 1997 and had no relationship with the Sinistar franchise . After licensing the franchise from Midway Games that year , GameFX shifted the focus of the game and developed it as a sequel to the original Sinistar , which was released by Williams in 1982 .
