SLASH 6 was the last of six releases of SLASH that were based on NetHack 3.1.3.

Availability Edit

The source code is archived on Ali Harlow's website at [1]. It includes only the files needed to build for MS-DOS on the old Watcom compiler; it might be possible to build with Open Watcom after tweaking the code (it doesn't compile as is).

Various obscure FTP sites have binaries and earlier versions.

The adventurer Edit

SLASH 6 inherits the twelve roles of NetHack 3.1.3 and six roles from NetHack Plus, and adds two of its own; it also allows certain roles to have the player's choice of alignment, something new at that time:

All classes permit male and female adventurers, except the Valkyrie which must be female. Chaotic elves are called drow and get a different Quest from lawful or neutral ones.

Dungeon features Edit

Levels and branches Edit

The Dungeons of Doom are lengthened, to accommodate a number of new levels and branches, all of which are new to SLASH:

Code is present to implement the Black Market, inherited from NetHack Plus, and for The Wyrm Caves, but is commented out.

Gehennom is shortened, to reduce the number of mazes, and Yeenoghu, Demogorgon, Geryon, and Dispater are all given lairs.

Rooms Edit

New special rooms are:

giant courtNetHack--
leprechaun courtNetHack--
bad food shopNetHack--
real zooNetHack--
dragon lairnew
cockatrice nestnew

The bad food shop is not a shop in the usual sense. The wasp hive and "Room 11" from NetHack-- were removed.

There is one additional type of shop, a pet shop inherited from NetHack Plus.

Traps and fixtures Edit

The optional water weird fountain from NetHack Plus was removed. New fixtures, all new to SLASH, are the grave and the toilet.

SLASH 6 adds no new traps to NetHack 3.1.3.

The bestiary Edit

Most monsters that had their appearances changed in NetHack-- 3.1.3 are restored to their appearances in NetHack-- 3.0.10.

Potions have randomized appearances (except for water), appearing as one of ! ! ! ! ! ! ! ! ! ! ! ! !. SLASH 6 has these potions in addition to the ones in NetHack 3.1.3; the potion of polymorph is from NetHack-- 3.1.3, and all others are new:


All scrolls appear as ?.

SLASH 6 has one scroll not present in NetHack 3.1.3, a scroll of trap detection. It is new to SLASH.


Wands have randomized appearances, appearing as one of / / / / / / /. SLASH 6 has the following wands, in addition to those in NetHack 3.1.3:

wand of enlightenmentNetHack-- 3.1.3
wand of create hordenew

It should be noted here that spells in SLASH 6 (as in NetHack 3.1.3) work rather like wands, having a limited number of charges per read of a spellbook, and that spellbooks can only be read once. Many of these spells, among them enlighten, enchant armor, and enchant weapon, would be unbalancing if combined with the modern spellcasting system.
