GameStop has updated its site with a listing for a limited edition of Ninja Gaiden Sigma 2 exclusive to the retailer. The product page lists the $69.99 premium release as including an 80-page book divided into three sections: art from the game, a color Ninja Gaiden Sigma 2 comic and a strategy guide. There's no mention of special packaging for the edition, which is dated for September 29.
We contacted Tecmo for more info and were told that additional details will be disclosed within the next two weeks. The book sounds alright, but we're hoping for some additional goodies to sweeten the deal.
