OpenBSD

OpenBSD is a variant of BSD, one form of Unix. The project maintains the OpenSSH protocol which has been ported to other operating systems such as Windows and Linux. The base operating system includes Hack 1.0.3, and the OpenBSD Packages Collection includes copies of NetHack, Falcon's Eye, SLASH, and SLASH'EM. The description for NetHack reads as follows:

"P.S. This is a very addictive game, with its whole wacky culture. And even a newsgroup dedicated to it (rec.games.roguelike.nethack). Don't say we didn't warn you !"

Latest release

The current latest release of OpenBSD is version 7.6, which should include Hack 1.0.3 at the location /usr/games/hack if the system has the install set games-XX.tgz installed, and can be played by typing /usr/games/hack at the command line. The OpenSSH Secure Shell implementation is also included, which allows the user to play NetHack through connection to a public server.

OpenBSD 3.9

For OpenBSD 3.9, there are packages of Falcon's Eye 1.9.3, NetHack 3.4.3, SLASH E8 and SLASH'EM 0.0.7E7F1. (Note that the latest version of SLASH'EM is 0.0.7E7F2.) The easiest way to install them is to go to the package lists, choose your architecture, look for packages called "nethack", "falconseye", "slash", and "slash-em", then give their FTP urls to the pkg_add command.

Ports Tree (Advanced Users)

Users wishing to play NetHack with patches will need to compile the game themselves—/usr/ports/games/nethack/patches is worth consulting for hints on how to configure the sources.
