I have recently been researching into encrypting my scripts for a big game I've been making. That of course has flaws to it. I was wondering if Linked Scripts are unhackable since they can only be opened and run from the original game where they were created.
No, I don't think they do. They are just the same as a normal script, the only difference being that every script with the LinkedSource of the script gets changed when the script changes.
So, no protection, sorry.
Hope I helped! Please don't downvote if I got the answer wrong, I am not 100% sure the above is right.
