## What it is
A modified, cross-platform port of Valve's Source game engine (based on the 2017/2018 leaked codebase), extended to run on Android, macOS, FreeBSD, Windows, and Linux including ARM and 64-bit builds. It adds modern toolchain support, PBR, touch input, and fixes many bugs, and is explicitly not for commercial use.

## Use cases
- build a game on the source engine
- port source engine games to android
- run half-life 2 on linux or arm devices
- compile source engine with modern toolchains
- play source engine maps without steam
- experiment with pbr rendering in source engine

## When to choose
- you want to build or mod games using the Source engine on modern platforms including Android or ARM
- you need a 64-bit, modern-toolchain-compatible Source engine build
- you want Source engine features like PBR or touch input without Steam dependencies

## When to avoid
- any commercial project - the leaked codebase forbids commercial use
- you need a fully supported, officially licensed engine
- you need a modern engine with active vendor support rather than a community patch effort
