This is a re-creation of the maps of all eight levels of Ultima Underworld for Unreal Tournament, made by Ryan “Zerker” Armstrong. Each map has been “enhanced,” according to the producer, over the original version, so expect your favourite areas from the classic game to have a great new feel to them. All of the maps support the Deathmatch play mode; a few of the maps also support other game modes. (Check the project’s website for a complete listing. And for a pretty concise summary of the game itself and the nuances of every level thereof.)
Of course, the maps also require Unreal Tournament to play. Copies of the game for Windows, Mac, and Linux can still be found online, though they won’t necessarily be cheap or in stock in large quantities. You can also find the game for direct download on Steam, and (for the same price) at Good Old Games.
Note: this is not a complete remake, in that it does not implement the various races or the plot of Ultima Underworld. That said, having a complete set of high quality maps to begin with would serve to cut down on the time it would take to develop a complete remake of the game using the Unreal Tournament engine.
