## What it is
The official source repository for NetHack, a classic single-player roguelike dungeon exploration game descended from Rogue and Hack. Version 5.0 modernizes the codebase with C99 compliance, cross-compilation support, and Lua-based level/dungeon configuration replacing yacc/lex compilers.

## Use cases
- play a classic roguelike dungeon crawler
- build NetHack from source for my platform
- cross-compile NetHack for another operating system
- contribute bug fixes or features to NetHack
- create custom dungeon levels with Lua
- study the source code of a legendary roguelike

## When to choose
- you want to play or modify the canonical NetHack game
- you need a deeply replayable single-player roguelike with decades of history
- you want to build a roguelike for many platforms from one codebase

## When to avoid
- you want a modern graphical 3D game
- you need multiplayer or online play
- you want a lightweight casual game with a short learning curve

## Facets
- artifact type: application
- maturity: active
- function: game-engine, interpreter
- domain: gaming-tools, cross-platform
- platform: cross-platform, windows, cpp
- tags: roguelike, dungeon-crawler, c99, lua-scripting, open-source-game, game-development, linux, macos
