Greetings!
Around the beginning of October of this year, Unity announced that they had discovered a potential security exploit in their engine, starting from version 2017 and going forward.
They discovered this security flaw internally and have no reason to believe anyone has been affected by it. They have also patched all versions of their engine to remove the issue. On their recommendation, I rebuilt the game with their patched engine. Crimson Glaive Sigma (demo included) is no longer vulnerable to this exploit.
Have a nice spooky month!
