Project Berkley was the code name for Shenmue that was included as a bonus GD-ROM disc with the Virtua Fighter 3tb game for the Sega Dreamcast. This disc was only made for Japan. The video gave details about the Shenmue game and beta footage of what's to come at the time.
- In the alley of Heartbeats Bar in Shenmue, the word "Berkley" is written in red spray paint on the wall. This is a reference to Project Berkley.
- "Berkley", as Yu Suzuki explained, is Janglish (Japanese/English) for a Japanese word which means to pretend you don't know anything, because the developers wanted to keep Shenmue a secret.
