## What it is
AssetRipper is a GUI application for analyzing Unity game files, extracting and converting assets back into native Unity engine formats. It supports Unity versions 3.5.0 through 6000.4.X and helps developers inspect dependencies, broken references, and leftover code in builds.

## Use cases
- extract assets from a Unity game build
- find accidentally included dependency assets in my game
- convert game assets back to native Unity format
- find broken asset references causing issues in my build
- analyze which code was not trimmed from a Unity build
- inspect Unity game files with a GUI

## When to choose
- you need to analyze or recover assets from Unity game files
- you are a Unity developer auditing your own build for stray assets or broken references
- you need support for a wide range of Unity versions from 3.5 to 6000.x

## When to avoid
- you need to work with non-Unity game engines
- you want a headless CLI-only pipeline (this is primarily a GUI tool)
- you need pixel-perfect project reconstruction without the paid Premium edition
