Def Jam: Icon 2

This game was never completed and/or given a public release. As a result of this, keep in mind that the developers might have used or deleted some of the content featured here, had the game actually been released.

This prototype is documented on Hidden Palace.

Def Jam: Icon 2 was going to be the sequel to Def Jam: Icon, but was cancelled due to poor reception and the expiration of the Def Jam license.

A build dated November 2, 2007 was found on a devkit HDD. It seems to be from early in development, containing a lot of assets from its predecessor.

Development Leftovers#

Found within the build are some .txt files from the devkit, the earliest being dated October 25, 2007.
