Unreal is an old-school first-person shooter pc game. It was developed by Epic Games and Digital Extremes and published by GT Interactive and released in 1998. It still is one of my favourite out of the old-school shooters in that era.
Since its release the franchise has had one sequel, one expansion and two different series based on the Unreal Universe. Unreal Mission Pack: Return to Na Pali is the is the expansion developed by Legend Entertainment and released in June 1999. It added seventeen new missions to the single player campaign of Unreal. It still kept the same atmosphere/feel, gameplay and mechanics while adding a few things like enemies, weapons and environments.
It would later be bundled together with Unreal in a new package called Unreal Gold and re-released. The game was then updated to then run on the Unreal Tournament Version of the game engine.
Engine
Unreal and Unreal Mission Pack Return to Na Pali uses the first generation of the Unreal engine developed by the founder of Epic Games Tim Sweeney. It was designed to compete with the original Quake and Doom. The engine’s software renderer brought a host of new graphical features and improvements for its time. These things include coloured lighting, a limited form of texture filtering and the ability to utilise detailed texturing.
