Kadokawa Games will be releasing a premium edition for Killer is Dead for the same price as the standard version. It is unknown whether this is exclusive to Japan.
The Killer is Dead premium edition will have a reversible jacket and a code that lets you download "Beauty & The Beast & The Lingerie." Killer is Dead also has three other bonuses that come with it: the Temptation of Miss Vampire gigolo mission, an extra episode where Mondo acts as an executioner, and a peeping tool that helps greatly during gigolo missions.
Killer is Dead will release on August 27th worldwide on PlayStation 3 and Xbox 360 by Xseed and Deep Silver. There are no details regarding pre-order bonuses at this time.
