The original Catherine came out in 2011, and the updated Catherine: Full Body hit other platforms in 2019. Now the experience is set to come to Switch next month, and Atlus is still doing what they can to prevent spoilers.
Atlus has shared a message on their official Japanese site about streaming/video uploads for Catherine: Full Body. First up, any footage/audio uploaded or streamed can only be for personal use, and not to profit off of. All footage has to include copyright messages for “ATLUS” and “SEGA.” Lastly, players are not allowed to share videos or screenshots from the Golden Theater story mode. That includes from the 6th day all the way to the ending.
