Slordax: The Unknown Enemy is a vertically scrolling shooter for MS-DOS, published by the software company Softdisk in 1991. The game has 16-color graphics that scroll smoothly across the screen, which was technically impressive for a PC game at that time. Slordax was developed at Softdisk in September and October 1990 by programmers John Carmack and John Romero, game designer Tom Hall and artist Adrian Carmack. It was the first game that they developed as a team. Soon after they would leave Softdisk to form their own game company, called id Software.
