## What it is
Teeworlds is a free, open-source retro multiplayer shooter supporting up to 16 players in game modes like Team Deathmatch and Capture the Flag. It includes a client, dedicated server, and map editor, built in C/C++ with SDL2 and OpenGL.

## Use cases
- play a free online multiplayer shooter with friends
- host a dedicated game server for deathmatch or CTF
- design custom maps with the built-in map editor
- build the game from source on Linux, macOS, or Windows
- run a headless game server without graphics libraries
- contribute to or fork an open-source multiplayer game codebase

## When to choose
- you want a lightweight, free retro-style multiplayer shooter
- you need a cross-platform game that runs on Linux, macOS, and Windows
- you want to self-host game servers or create custom maps
- you're looking for a real-world C++ networking/game codebase to study or modify

## When to avoid
- you want modern AAA 3D graphics or single-player campaigns
- you need a game engine or framework to build your own game rather than a finished game
- you require a permissively licensed codebase for commercial reuse (license is custom, not standard OSI)
