High Quality Content by WIKIPEDIA articles! 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.
