Unreal (demo)
Unreal is a demo created by Future Crew in 1992.
It was created for the Assembly 1992 PC demo competition which it won, defeating Overload by Hysteria. It's widely considered the first megademo (a demo that consists of multiple parts) ever on the PC and essentially opened the floodgates for the PC scene.
System requirements
The demo states that "[it] requires a 386 computer [and] runs perfectly on a 486/33Mhz with Tseng Labs SuperVGA". It supports various sound devices, such as the SoundBlaster, SoundBlaster Pro and the then ascending Gravis Ultrasound 9to which the demo defaults.
