Suggestion Name Laser tripwire alarm
What's Being Added/Removed/Changed an addon for tripwires, the closest addon I have found is https://www.gmodstore.com/market/view/rprotect
It is no longer supported however I don't think it is broken that much and would be easy to fix up or make your own version of this if needed. I have seen this working on other servers recently.
Why It Should Be Added/Removed/Changed It would make people feel safer to leave their base and go have fun and interact with others rather than sitting in their base all day long because printers are expensive to setup.
