The original Catherine was released in 2011, and the Catherine: Full Body update hit other platforms in 2019. The experience should now arrive on Switch next month, and Atlus is still doing what it can to avoid spoilers.
Atlus shared a message on his official Japanese website about streaming / downloading videos for Catherine: Full Body. First of all, any footage / audio downloaded or streamed can only be for personal use and without benefit. All images must include copyright messages for “ATLUS” and “SEGA”. Finally, players are not allowed to share videos or screenshots of the Golden Theater story mode. This includes from the 6th day until the end.
