UnNetHack and
NetHack-De are roguelike, single-player role-playing games for Windows/Linux/BSD
About
UnNetHack is a fork of NetHack, a single-player roguelike video game in development since 1987.
It features more randomness, more levels, more challenges and more fun than vanilla NetHack, trying to be the game NetHack would be if it were still in development.
There is a project page on sourceforge and a public server at un.nethack.nu.
For discussion, join the IRC channel #unnethack on irc.freenode.net or post to rec.games.roguelike.nethack.
The current released version of UnNetHack can be downloaded there. The development code is available from the subversion repository.
NetHack-De is a German translation of NetHack.
Its project page is on sourceforge and the current version can be downloaded there.
