UnNetHack

Screenshot of UnNetHack

UnNetHack 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 improvements designed to reduce tedium, and many gameplay-related changes. Since 3.6.1 it also bundles a graphical tiles UI for Windows. The 5.1.0 version's default Windows tiles are not that good but it is bundled with DawnHack tiles.

For discussion, join the IRC channel #unnethack on irc.libera.chat or post to rec.games.roguelike.nethack.

The latest development source code is available from the Git repository, and there are several public servers where it can be played online - the current stable version is UnNetHack 6.0.8.

For those curious what is added in UnNetHack, here is the Change Log that list major changes. If you want to see a complete list of changes, you can take a look at the commit browser.

Changes from NetHack 3.4.3

For the following changes, numbers in brackets before a change indicate the version the change was implemented, and game versions in brackets at the end of a change indicate if the change was inspired by or came from another fork of NetHack. Changes in each category are also listed in order of general relevance to gameplay instead of version number implemented.

In addition to all the listed patches and changes below, UnNetHack also fixes many vanilla bugs, such as the Astral call bug. Some of the changes made between 3.4.3 and 3.6.0 were taken from, or inspired by UnNetHack changes, and other variants incorporate content that originally appeared in UnNetHack.

Elbereth

UnNetHack makes several changes to how Elbereth is used and tracked in-game.

Replaced Objects

• (3.5.3) Replaced the scroll of amnesia with the scroll of flood, which creates pools around/under the player
