Hack 1.0.2

Hack 1.0.2 is the third public release of Hack. Andries Brouwer published it to the (now-obsolete) Usenet newsgroup net.sources.games in April 1985.


Google Groups has archived nine of the ten original postings to net.sources.games, but not part 2. This is possibly due to the same problem with the rumors file which affected part 15 of Hack 1.0:

These are mostly typical shar files. Part 10 is a bit different in that, after extracting its contents, it invokes ed to patch some of the files from previous parts.

A second archive also preserves Hack 1.0.2. Part 2 appears to be intact in this archive, but parts 1 and 8 are somewhat altered, most notably changing the wizard mode account to "kimery". Mrynet.com has another copy of the second archive of Hack 1.0.2. Andries Brouwer has mirrored both archives on his web site.

Ali Harlow[1] has a Hack 1.0.2 distribution at [2]. This distribution does not have the benefit of the second archive.

Significant changes

The swamp and the giant eel are drawn from PDP-11 Hack and the Hack 1.0.2 source credits the creators of that version, Michiel Huisjes and Fred de Wilde, for the inspiration.

The adventurer

The player may choose a Tourist, a Speleologist, a Fighter, a Knight, a Cave-(wo)man, or a Wizard. All classes permit male and female adventurers.

The adventurer has experience, hit points, armor class, and strength. He may advance to experience level 14.

The initial pet is a little dog.

Dungeon features

The dungeon in Hack 1.0.2 has no branches; there is one way up and one way down. The first 25 levels or so consist of rooms, and beyond that, the adventurer encounters mazes.

Dungeon level 30 and deeper are designated as "Hell". Entering hell without fire resistance is an instadeath. Due to a bug, fixed in Hack 1.0.3, one could enter hell with a ring of fire resistance and take it off once there. (Gremlins and self-polymorph did not yet exist.)

Special rooms are shops, beehives, crypts, swamps, treasure zoos, and vaults.

Traps are:

The Amulet of Yendor is found in the possession of the wizard of Yendor in a maze level. He is in a small room in the center of a maze level, surrounded by water and accompanied by a hell hound.

Other maze levels have wands of wishing tucked under a boulder in a dead-end square. (Yes, there's more than one.) Since NetHack 3.1.0, one version of Medusa's lair has a random wand in a similar spot, commemorating the former location of the wand of wishing.


Monsters that are new to this version are noted in boldface.

New objects to this version are indicated in boldface.


Hack 1.0.2 has only one artifact, Orcrist. Any two handed sword may be named Orcrist and will do d10 extra points damage to orcs. There can even be more than one Orcrist.


Only the Amulet of Yendor and the cheap plastic imitation exist in Hack 1.0.2.


Food items in Hack 1.0.2 are:

The tin did not contain the remains of monsters, but rather a randomly-chosen food such as peaches or, if the adventurer is lucky, spinach.

The dead lizard was a found object rather than a corpse; live lizards did not exist in Hack 1.0.2. It could reduce confusion and carrying it cancelled the effects of the new moon, but had no effect on stoning as this was still an instadeath.


Weapons in Hack 1.0.2 are:


Tools in Hack 1.0.2 are:

The ice box is the only container. Then as now, it preserved corpses, and was generally too heavy (and too rare) to be useful for inventory management.


Armor items in Hack 1.0.2 are:


Potions in Hack 1.0.2 are:


Scrolls in Hack 1.0.2 are:

The scroll of damage weapon acts as the modern scroll of enchant weapon does when cursed. The scroll of genocide acts, in all cases, as the modern blessed scroll; but most symbols refer to only one monster anyway.


Wands in Hack 1.0.2 are:


Rings in Hack 1.0.2 are:

Because charisma does not exist in Hack 1.0.2, the ring of adornment is a useless item.


Gems in Hack 1.0.2 are:

and worthless pieces of blue, red, yellow, and green glass.

Other items

Other items not appearing in the above categories are:

It is not possible to pick up an iron chain, nor can they be generated from iron golems, because these do not exist in Hack 1.0.2.
