v0.2.1 — Linux / Steam Deck support

OpenChaos v0.2.1 — Linux / Steam Deck support

Fan modernization of Urban Chaos (1999). Requires original game files (Steam/GOG).

What's new

• Added Linux x64 support — fully playable on Steam Deck, gamepad works (native controller and DualSense tested) (0ab1f8d1, 106c35b0, 20b51319)

Current state

This is an early alpha. The game launches and is partially playable, but expect:

• Crashes (especially on Windows)
• Visual glitches
• Fixed window resolution (no resize yet)
• No launcher or settings UI

How to run

1. Download the zip for your platform
2. Extract into your Urban Chaos game folder (where the data folder is)
3. Run OpenChaos.exe (Windows), OpenChaos.command (macOS), or OpenChaos.sh (Linux)

Requirements

• Original Urban Chaos game files (Steam or GOG version)
• Windows 10+ (x64), macOS 12+ (Apple Silicon), or Linux x86_64 (Steam Deck compatible)
