NetHack is an open source roguelike adventure game. NetHack evolved from Hack, and has been in continuous development for nearly twenty years. The first version of NetHack was released on July 28, 1987.
NetHack is characterized by its many surprising events. Dipping, quaffing, scrawling, and many other actions can often have hilarious and/or infuriating results. This has yielded the popular phrase, "The Dev Team Thinks of Everything." (TDTTOE)
Nethack features 13 roles which serve as the base of your avatar's starting abilities.
Roles also restrict races and alignments that your avatar may pick from.
Nethack features 5 races which help determine your starting statistics and abilities, as well as how you get along with the various creatures that populate the Mazes of Menace.
