Sega has released new downloadable content for Hell Yeah! Wrath of the Dead Rabbit today. Two batches of new material are now available, the "Pimp My Rabbit" pack and "The Virtual Rabbit Missions."
The "Pimp My Rabbit" pack comes with new masks and skins for the jet pack driller. There are also skins from other Sega franchises, but I'm not seeing any indication that there is ToeJam or Earl anywhere in this, so I'm not sold. If you want to play dress up with the King of Hell, however, that pack will run you $2.99 (240 MSP on Xbox Live).
"The Virtual Rabbit Missions" contains more in terms of game content, containing more than fifty challenges to play through. With that comes a higher price, though, and this content is priced at $4.99 (400 MSP).
