NetHack

NetHack is a roguelike computer game. It is an evolution of an earlier game called Hack which was itself an evolution of the much more famous Rogue. The name NetHack stems from the fact that its development was originally coordinated through the Internet; it is not a network/multiplayer game. NetHack is traditionally played using text-only graphics (in a manner similar to ASCII art). You take the part of a dungeon-delving hero in search of the Amulet of Yendor. The quest is played through at least 40 randomly created levels, each containing many monsters, items, magical artifacts, and much, much more. The current version of NetHack is 3.4.3, released on December 8, 2003.

Game

Before playing the game, you are invited to select a race, class, and alignment for your character, or allow the game to create a random character for you. There are traditional character roles such as knights, wizards, rogues, and rangers, but there are also unusual ones, including tourists and cavemen. Your character's class and alignment dictate what god you serve in the game; if you keep your god happy you can receive aid and gifts.

After contructing your character, your task is introduced:

After the Creation, the cruel god Moloch rebelled against the authority of Marduk the Creator. Moloch stole from Marduk the most powerful of all the artifacts of the gods, the Amulet of Yendor, and he hid it in the dark cavities of Gehennom, the Under World, where he now lurks, and bides his time.

Your character is initially accompanied by a pet kitten / little dog, or if you are playing a Knight, a pony. You can name your pet, and you can tame more pets along the way - domestic animals can be tamed by feeding them, and other monsters can sometimes be tamed by magic. Pets are very useful, not only for assisting you in combat, but also for detecting cursed items and stealing from shops.

This game is unparalleled in scope: hundreds of unique items, situations, monsters, and personages provide opportunities for interaction with the gameworld. Some interactions (and bugs) are rare and occasionally amusing. For example:

(This would be referred to as YAAD or Yet Another Annoying Death.)

It is often said that "the DevTeam thinks of everything" - whatever you can think of for your character to do, they will probably have thought of a plausible response.

For example, attempting to dip a potion into itself would produce:

Or, being burdened while going down the stairs would produce:

Bugs, funny messages, stories, experiences, and ideas for the next version are discussed on the Usenet newsgroup, [news:rec.games.roguelike.nethack].

Part of what marks the game is its constant improvement and growth, with new versions released whenever the DevTeam, a group of unpaid programmers, feels like it.

To win the game, a player would ascend and become a demigod or a demigoddess. This is achieved by sacrificing the Amulet of Yendor to a player's deity after playing some of the hardest levels in the game.

Graphics

The following is a sample from a typical game session with what would be considered "improved graphics" with extended ASCII symbols:

Key:

• @ - you
• d - your dog
• $ - money
• ` - boulder or statue
• < - staircase up
• ? - scroll
• _ - altar
• + - closed door
• ( - tool (lamp, pick-axe, bag, etc.)

Below the map is the status line. First there is your name and professional ranking that is based on your experience. St stands for strength, Dx for dexterity, Co for constitution, In for intelligence, Wi for wisdom, Ch for charisma and Chaotic is your alignment. The next line shows the dungeon level you're on (increasing when you go deeper), money, hit points, magical power, armor class, experience and elapsed time (number of turns). Your hunger status, ranging from Satiated down to Fainting, would be shown next but it's currenly normal and thus not displayed.

Apart from the original text mode, there are interfaces that replace text mode screen representations with images called tiles. For example, instead of the symbol "?", a picture of a scroll is shown.

Notable (non-player) characters

• The Wizard of Yendor, also known as Rodney (which is "Yendor" spelled backwards)
• King Croesus, lord of Fort Ludios.
• the Oracle of Delphi.
• Vlad the Impaler, a figure based on Vlad III Dracula and the Dracula story.
• The Gorgon Medusa, also from Greek mythology.
• Various demons, like Asmodeus, Demogorgon and Orcus.
• The Shopkeeper Izchak. (The character is named after one of the founding members of the DevTeam, who passed away in 1994.)

Notable creatures

• The cockatrice: a typical example of a complex Nethack monster. Its touch can turn you to stone, so attacking it with your bare hands is not recommended. If you kill one and it leaves a corpse, you could wield it as a weapon, and turn other monsters to stone—but you'd better be wearing gloves. Again, "the DevTeam thinks of everything".

• The floating eye: a monster without any active form of attack, this is one of the most dangerous creatures to the freshling nethacker. If you attack (run into) a floating eye when not blind and not reflecting, there is a very high chance of it immobilizing you for many turns, leaving you open to attacks from other creatures that roam the Dungeons of Doom.

• The soldier ant: even though this creature has no special attacks whatsoever, it often comes as a surprise for the unprepared hacker. These critters move in herds, are very fast, hard to hit and hit hard themselves. On the alt.org public nethack server, they are the top death reason for players.

• The nymph: taking its origin in Greek mythology, these creatures are females of astounding charm. They manage to entice men and women alike into helplessness, stealing the belongings of an adventurer who has fallen into their hands, and leaving him bait for the more deadly creatures of the Dungeons, or, in the worst case, to die at the hands of their own equipment wielded by the nymph.

Other versions

There was a commercial version called Dungeon Hack with a first-person view, but it left out many of the little features that makes NetHack worthwhile even after years of playing (and it usually takes years and years of playing to win).

One variant, Falcon's Eye, offers an graphical isometric view of the dungeon map. However, Falcon's Eye is now an abandoned project and replaced by its successor, "noeGNUd".

Many experienced NetHack players prefer the original text mode interface, as they feel the graphical alternatives deter attention from playability and the use of one's imagination.

NetHack is an open source game, so anybody can fool around with the insides and make up new variants. As of June 2002, the only variant which is under active development is Slash'EM (Super Lots of Added Stuff Hack - Extended Magic).

Nethack-el is an emacs major mode for playing nethack.
