About this project

Unofficial fix patch on top of Shadow of COOP 8.0 (an extra .db appended to coop.addon). Fixes crashes and stuck quests and unlocks the true ending. All 18 levels boot-tested on a dedicated server and an in-engine self-test passes 20 of 20; no scripted full story run or automated two-client run yet. Tools MIT; patched files remain Shadow of COOP / GSC files.
