NetHackWiki

NetHackWiki is the largest wiki about nethack on the internet. It contains game information, spoilers, and other information related to both NetHack, and related games such as SLASH'EM. It's actually the successor site of wikihack when the editors voted to leave by >80%, due to Wikia forcing obnoxious formatting changes onto the site.

NetHackWiki, like most NetHack sites on the Internet, has no official affiliation with NetHack or  NetHack' s DevTeam.
