Shenmue developer Ys Net has threatened legal action over a widely-circulated video designed to look like leaked footage of Shenmue 4.
The footage popped up on social media last week and was promptly shared by numerous websites, even as questions regarding the video’s origins and authenticity swirled.
Now, Ys Net has released a statement to confirm that the footage “has absolutely no connection” to itself and uses the company’s logo without permission. Additionally, Ys Net claimed that such acts “may amount to trademark infringement and unfair competition” and therefore it was now preparing “appropriate measures” and exploring legal options.

While some fans took the lengthy “Shenmue 4” clip as too elaborate to be fake, others pointed to a handful of wonky animation effects and its fan-baiting story to suggest it was an elaborate creation made by a fan using generative AI.
