 Development of Sinistar : Unleashed , originally titled Out of the Void , began in 1997 . It was handled by GameFX , a small game developer consisting of former members of Looking Glass Studios . At first , the project had no connection , or gameplay similarities , to the Sinistar franchise . When the studio acquired the rights for the Sinistar franchise that year , it decided to refocus the development of the title to fit into the newly acquired property . It altered the game to introduce similarities to Sinistar , although the graphic structure remained unchanged . During development of the game , AGH noted that the final product was expected to be " a combination of Out of the Void 's graphical flash with Sinistar 's fast and frenzied action . "
