GruntHack is a variant of NetHack, with the objective of extending and enhancing gameplay that exists in vanilla NetHack. It a compilation of many third-party patches and some of the author's own best work. Some of the changes are similar to those in SLASH'EM or in NetHack brass, but GruntHack takes a different direction from either.
The current release is 0.2.0 alpha 4, released on 30 April 2012.
A public GruntHack server is available at http://grunthack.org/, monitored on IRC on #grunthack at freenode.net.
GruntHack is distributed through its GitHub repository found at https://github.com/sgrunt/GruntHack/.
This variant is no longer being developed.

Additional changes from NetHack 3.4.3
Changes include, but aren't limited to the following:
Added in 0.1.x
- Most areas of the status line acquire colours when an important change happens, e.g. your attributes turn green if they've just increased or red if they've decreased.
- In the tty windowing system, areas of the map not in your current line of sight now take on a darker colour.
- Hallucination causes the entire map to take on strange colours (in tty GruntHack) and also distorts your perception of items. Fortunately as it times out its effects are gradually reduced.
Added in 0.2.x
- showrace has been split into showrace (with the vanilla showrace behaviour of only affecting the player) and showmonrace (for racial monsters).
Added in 0.1.x
- Gehennom has been remodelled - instead of a series of mazes, it is now a series of caverns complete with rivers of lava and hordes of demons.
- The Gnomish Mines contain pools of water and the occasional river.
- The Elemental Planes appear in random order in the end game.
Added in 0.2.x
- Some additional Sokoban levels are present.
- You now can obtain one of three rewards from Sokoban. (Whether this is random or not depends on how clever you are.)
- Yeenoghu, Geryon, Dispater, and Demogorgon now have their own fortresses in Gehennom. Gehennom has been extended by five levels to allow room for this.
- Killing the quest leader opens the stairway to the rest of the quest (thus accidental conversion is less likely to render the game permanently unwinnable).
Added in 0.1.x
- Optionally, players can play as a kobold, ogre, or giant, each of which brings unique problems due to their respective sizes.
- The arbitrary alignment restriction on elves has been removed; they can now play any alignment (and can play a few new roles as well).
- You can cast monster spells while polymorphed into a spell-casting form.
- Low dexterity causes fumbling on an intermittent basis. Gauntlets of fumbling and fumble boots set dexterity to 6 as a consequence.
- Wearing greased gauntlets grants "slippery fingers" extrinsically.
- Death messages while immobile now reflect the reason for immobility.
- Death messages while stuck in creature form now reflect the method of death as opposed to plain "stuck in creature form".
- Wizards can identify objects with abnormal magical properties as having a magical aura, e.g. "a magical helm".
Added in 0.2.x
- Several new spells, such as the monster-inspired "touch of death" and "psi bolt" and the deferred "flame sphere" and "freeze sphere".
- Casting a spell successfully adds 50-149 turns until the spell is forgotten; without casting a spell at all, it is now forgotten in 10000 turns instead of 20000.
- When prompted for a direction, entering an invalid direction will now prompt the player again for a direction; cancelling requires the player to press Esc.
- The travel command now finds dungeon features (most notably stairs) even if an item is on top of them.
- If the player is a giant, they can force-move onto a boulder rather than push it.
- If the player is a giant, moving onto a boulder square in Sokoban is prompted for rather than always occurring if the boulder is block.
- There is now a #tip command for emptying out containers on the floor or in your inventory.
Added in 0.1.x
- Some classes of monster can have a race, much as the player does. Some monsters have been merged as a result. showrace now additionally shows the race of monsters as well as yourself.
- Shopkeepers that hate your race will charge extra.
- Monsters that polymorph will revert to original form if killed; their polymorph can also time out.
- Monsters can now use ranged weapons against other monsters, including polearms and monster spells.
- Monsters can use scrolls of remove curse.
- Intelligent pets will actively seek out better equipment to make use of.
- Monsters can use additional types of equipment that grant magical effects just as the player can.
- Monsters actively target your pets as well as you.
- The behaviour of covetous monsters has been improved. Most notably those not capable of teleporting can no longer teleport. If they manage to acquire their desired target they will attempt to flee effectively.
- Monster displacement is implemented. shimmering dragons are re-enabled as a consequence.
- In addition to the shimmering dragons, the vampire mage and vorpal jabberwock are enabled.
- Kings are now guaranteed to appear in throne rooms.
- Pets will not eat if they are not hungry. Unintelligent pets can choke if you overfeed them; intelligent pets can keep food with them.
- Gelatinous cubes and water elementals now have an engulfing attack, making them much more fearsome opponents.
- Puddings have their maximum HP halved when they divide.
- Puddings are now split with edged weapons as opposed to any iron object.
- Messages for monsters missing you are more verbose, explaining what piece of armor stopped the blow.
- Monsters can now become ill and die from their illness.
- Zombies now have a sickness-inducing bite attack, and have a chance of eating your brains on a sucessful hit. If you die to a zombie, you will become a zombie.
- Zombies will now attack any living creature and vice-versa.
- Cancellation now kills all types of golems.
- Dragons now possess an engulfing attack.
- Vorpal jabberwocks now possess the ability to behead as their name would suggest.
Added in 0.2.x
- The beholder's remaining gaze attacks have been implemented; thus the beholder has been enabled.
- There are now queens and ladies in addition to kings and lords. (Suggested by ishanyx in #nethack.)
- Player monsters now have a chance of being randomly generated in the dungeon, and will carry level-appropriate equipment.
- Monster spellcasting has been overhauled - monsters will now cast spells from the pool of player spells, instead of their own unique spells. (This behaviour is optional and controlled by #define COMBINED_SPELLS in config.h.)
- Monsters can now use some additional items (wands and containers particularly).
- If you throw an intelligent pet an item that they are capable of using, they will catch the item and (if applicable) use it immediately.
- Grudge-bearing monsters are now more likely to attack their targets.
- Conversely, covetous monsters are less likely to target other monsters if they do not have an objective in sight.
- Bumping into a peaceful monster while invisible no longer angers it.
- Monsters (and you!) can now be buried in the same manner as objects.
- Water elementals now deal rust damage both passively and actively.
- Non-human, non-elven racial monsters whose base types are symbolised by an '@' now once again respect scary squares.
- Attempting to teleport away a monster with teleport control causes it to choose where it wants to teleport.
- Covetous monsters are much better at path-finding when looking for their targets.
- Non-flying, non-levitating monsters on the Plane of Air are subject to the same movement restrictions as the player.
- Stunned and confused monsters now wobble as the player does in the same circumstances.
- Medusa's passive gaze attack now affects all monsters.
- Farlooking at a monster will reveal equipment they are currently wearing or wielding.
- Monsters with passive fire attacks now deal passive fire damage to objects.
- Monster petrification is now a gradual process for cases where it would be a gradual process for the player under the same circumstances.
Added in 0.1.x
- Non-artifact objects can have additional properties (e.g. ___ of fire resistance).
- Object material is now determined on a per-object basis.
- Foobanes deal additional damaging effects to their targets.
- Hitting monsters with a wielded scroll or wand causes some of the object's magic to be released. Throwing scrolls has a similar effect.
- Hitting a water elemental with a potion of acid causes the potion to explode.
- Potions of gain ability and wands now interact plausibly.
- Unidentified fake Amulets of Yendor cannot be put in containers.
- Some types of explosions now scatter objects (including breaking statues, boulders, and corpses).
- Effects of projectile weapon properties now stack with those of their launcher.
Added in 0.2.x
- Objects can now be invisible, with many associated side effects. (Some cues for this were taken from the Extended Invisible Objects patch by Nephi, but the implementation is entirely original.)
- Exploding a bag of holding no longer destroys the contents of the bag; instead they are scattered throughout the dungeon, as is the player.
- Polymorphing magical items now more reliably yields magical items.
- The Banes now warn of their respective monster classes, if they did not do so previously.
- Dragging a ball and chain around while underwater now causes them to rust away (as would happen if the ball was being carried).
- Two additional item properties have been added: hunger and aggravation.
- Items can now bear the same name as an artifact (no more "While engraving your [hand] slips"). This removes the ability to #name-test objects.
- Behaviour between items with similar purposes with respect to the Planes is now more consistent.
- At least seven candles are now guaranteed to be generated in a lighting store.
- Crossbows now fire a set range regardless of strength; they require high strength to fire mulitple shots.
- Items with abnormal magical properties are now generated more frequently at lower dungeon levels.
- New item: scroll of detect magic. It acts as object detection for magical items (including those with abnormal magical properties), and sets the 'magical' flag for those objects as though the player was a wizard.
