OpenChaos v1.0.2 — Audio & stability fixes
Unofficial modernization of Urban Chaos (1999). Requires original game files (Steam/GOG).
What's new
Audio:
- Fixed level music stopping after the first track instead of playing continuously (sprint / stealth / combat music now loops as intended) — reported by Nervnobolnoj_beton (
4c65f5e8) - Fixed music fading out far too quickly when an action ends — the fade is now smooth and frame-rate independent (
4c65f5e8) - Fixed 3D positional sounds (fire, sirens, etc.) not attenuating naturally with distance — they now fade with distance like in the original (
8e04accd) - Fixed ambient events (sirens, thunder, animals) and the indoor/outdoor sound crossfade running too fast at high frame rates (

Stability:
- Fixed a crash in the "The Fallen" mission that occurred after talking to a certain NPC — reported by Nervnobolnoj_beton (
e6d5d8dc) - Internal assertion failures no longer crash release builds — the game keeps running, shows a brief on-screen notice, and writes the details to a log file (
e6d5d8dc)
Internal:
- Dialogue/cutscene voice waiting no longer busy-spins the CPU (
