April 29, 2008 Build
This prototype is documented on Hidden Palace.
An Xbox 360 build. While the executable is dated April 29, 2008, the last updated file (Season2.pac) is dated May 13, 2008, suggesting this was constructed specifically for previewing audio and wrestler entrances.
This prototype doesn't have any of its build data stripped out for the preview so there might be some unused content that can be accessed through modding since references to extra preview options are present in this executable but disabled by default.
