Mirror camera punisher (Pro)
Flipping the camera is annoying, and it does not delete a save or close the game. It works well in a first-person game.
Add FlipCameraPunisher to a child of the AntiCheat-Monitor, or use the Mirror Camera Punisher prefab. The usual limit is 450. It runs once. You can flip the view sideways or upside down.

Add the mirror camera punisher.
