0-Grav Games was an Australian video game developer company formed in 1992.
0-Grav Games supported the SNES and Sega Genesis as it started. They also released some games for the Sega CD, which didn't get a bunch of sales due to the Sega CD's failure.
In the pre-GTA era of 1995, 0-Grav released Street Scare for the PlayStation and Sega Saturn. It did not outsell GTA's first game from 1997, however. 0-Grav was even put in a lawsuit between them and Rockstar Games. Other than that, Street Scare has recieved negative feedback for its "lackluster quality." Despite being one of the earliest games on the PlayStation, that was little of an excuse.
