Sega is piling on the pre-order bonuses for Yakuza Black Panther 2. The game's special bonus DVD "Majima's Serious Rock" (which is a lot cuter when written in Japanese -- Majima no Maji Rock) will be joined by retailer-specific cards containing download codes for special moves and items.

Here's a look at the bonuses for seven shops:

GameTsutaya

WonderGOO

Geo

Joshin

Bic Camera / Sofmap

Yamada Denki

Yodobashi Camera

A few shops will also come with this special strap in addition to the DVD.
