## What it is
TrenchBroom is a free, cross-platform level editor for Quake-engine based games, supporting brush and entity editing with a high-performance 3D renderer. It supports Quake, Quake 2, Quake 3, Hexen 2, Daikatana, and custom engines via game configurations.

## Use cases
- create maps for Quake
- edit brush geometry for a Quake-engine game
- design levels with entities and textures
- build custom game levels for a retro FPS engine
- export maps as .obj files
- configure a custom game engine for level editing

## When to choose
- you are making maps for Quake-engine based games
- you need robust brush and vertex editing tools
- you want a free cross-platform level editor with 3D and 2D views

## When to avoid
- you need a level editor for non-Quake engines like Unreal or Unity
- you need full Quake 3 patch or brush primitive support
- you want a node-based or scripting-focused level design tool
