|NetHack is a free game. This means that the source code is available to be studied, modified, and distributed. Most projects look for help with testing, documentation, graphics, etc., as well.|
The player moves in turns in a dungeon, finding items and killing monsters to retrieve the fabled amulet of Yendor.
Nethack has a high replay value as every game is unique; essentially every level is randomly generated, items and treasure are randomly placed with unique and functional descriptions, and monsters are generated continually and randomly. There are thirteen different roles, 5 different races, and 3 different alignments. Nethack is extremely difficult, nearly impossible. The vast majority of its players have never beaten the game.
See NetHack release history for more details.
The most popular variant of Nethack is SLASH'EM (Super Lotsa Added Stuff Hack - Extended Magic). It features many new monsters, roles, races, items, levels, etc. It is also considered much more difficult than the original Nethack.
