Microsoft just published Ninja Blade all throughout Asia and it’s fully localized in a multitude of languages one of them, perhaps the most important one here, being English. The Asian release is region free too so there’s nothing to stop you from getting Ninja Blade if you can’t wait to slice and dice giant pillbugs.
A release date has not been announced for North America, but I expect Ninja Blade to come stateside soon. Gamestop claims we’ll have Ninja Blade in March now and the retailer will begin sending out codes to download a premium Ninja Blade theme on March 10.
