Dark Horizon is a space combat simulation game developed by Quazar Studio and published by Paradox Interactive. The game was released on September 26, 2008 in Europe and in North America on October 13, 2008. Dark Horizon is the sequel to Tarr Chronicles.
Dark Horizon initially debuted with incomplete joystick support. The game appeared to be released (and apparently designed) with the mouse and keyboard as the primary control system. The 184.108.40.206 patch however introduces joystick axis mapping to any game actions.
