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.

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. A 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. Note that because UnNetHack is a fork of NetHack 3.4.3, the limitations of Elbereth in NetHack 3.6.0 do not apply; It protects tiles you’re not standing on, there can be other text on the tile, it works in Gehennom and the Endgame, and attacking while standing on it does not erase the engraving or incur an alignment penalty (although attacking does have a chance to smudge the engraving if it’s not permanent)

Replaced Objects

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

  • (3.5.1) Uncursed scrolls of genocide only kill all monsters of the selected type on the current level, and blessed scrolls of genocide only let you globally genocide all monsters of one specific type, similar to a vanilla uncursed scroll. Cursed genocide remains unchanged
