"Death Smiles Mega Black Label will be coming to the Xbox 360 in the form of download content for the 360 version of Death Smiles. Both the package game and the download content will be available to Xbox 360 owners in Spring 2009.
Cave's Tsuneki Ikeda made the announcement today at Microsoft's Xbox 360 Shooting Festa event. Following a talk session with Death Smiles' director Junya Inoue, Ikeda introduced the changes being made for the 360 port, and announced the downloadable Mega Black Label content as a surprise.
The 360 version of Death Smiles is a port of an October 2007 vertical arcade shooter of the same name. Mega Black Label is the the latest update to the arcade title. It hit arcades in October."
