The original developer, GuysLabs, officially abandoned the project in early 2024. They issued a final patch that broke the DLL on purpose (a "kill switch") to prevent users from running outdated, insecure code. The "download link" (originally hosted on Mediafire and later GitLab) was removed on March 15, 2024.
Instead of looking for a sketchy download link, use these official methods to restore your guys.dll file. 1. Verify Integrity of Game Files (Steam)
use Easy Anti-Cheat, which frequently "patches" (blocks) modified DLL files to prevent unapproved mods .
