"A video showcasing the classic game Duke Nukem 3D with the High Resolution Pack (which can be downloaded at this address: http://hrp.planetduke.gamespy.com/ , however you need the fullversion of Duke Nukem 3D in order to play it).
HRP is still in the beta-stage, so there are still characters and plenty of textures that need to be remade.

This video are showing a big part of the opening level of Episode 1, with the HRP plenty of the world-textures have been replaced with a much more higher-resolution texture as well as all of the weapons/key cards and also the characters have gone from sprites to completely 3D, including Duke Nukem himself."
