UnNetHack 3.5.3 is a variant of NetHack 3.4.3, maintained by Patric Mueller and others.

The main intent of this fork is to put more randomness, challenges and fun into NetHack.

It features more levels, several UI changes like automatically opened doors and the pickup thrown patch and a lot of game play related changes.[1]

This is the start of a writeup similar to those for vanilla NetHack. It is a preliminary report and currently incomplete.

Significant changes Edit

UnNetHack incorporates a number of previously issued patches, among them the Heck² patch, menucolors, statuscolors, the dump patch with additional HTML output, the color alchemy patch and portions of the Lethe patch. It also has a few features of SLASH'EM, and fixes the Astral call bug among others. It also adds the town branch from nethack brass.

The Adventurer Edit

UnNetHack introduces no new roles but adds the vampire race from SLASH'EM as a playable race. Cavemen and Rangers, who in vanilla always start with a dog, can also start with a cat in UnNetHack.

Dungeon features Edit

UnNetHack adds to NetHack 3.4.3 several dungeon features, among them the Aphrodite level and the Black Market from SLASH'EM and various levels introduced by the Heck² patch. It also randomizes the order of the Elemental Planes.
