There are numerous levels, enemies, items and songs that were either dummied out or scrapped entirely in Vexx. This is because Acclaim was going bankrupt during the development of Vexx in 2003 and was forced to cut a good portion of the game's content in order to get it released. The very next year in 2004 Acclaim shut its doors for good. However, thanks to composer Nelson Everhart releasing many of these cut/test music in the form of the 'Vexxtras' soundtrack, we have a better idea of what the game's other music styles could've once been.
