This is a re-creation of “the entire first floor of Ultima Underworld for Unreal” created by Ryan “Zerker” Armstrong. The level fully supports all of Unreal’s default gaming modes, including co-operative play and botmatches.
It also implements some of the conditions present in the Abyss in Ultima Underworld. Zerker warns: “[d]on’t kill everything you see. Most of the humanoids are in fact, not hostile in this map, to be true to the original. There are still a few hostile Skaarj away from the settlements, but inside the settlements, they’re friendly. The secret door by the silver sapling must be shot to be opened, the one by the fountain of strength only opens from inside, and the one in the Grey Goblin settlement is unopenable. Oh, and if you get sick of trying to jump up the steps in the jumping puzzle, I sympathise with you, but there is some worthwhile stuff up there, if you can spare the minute needed to get it right.”
Naturally, the maps also require Unreal to play. Copies of the game for Windows and Mac 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, however, and you can also get it at Good Old Games.
