Tomonobu Itagaki announced at Microsoft's GDC keynote that the bloody ninja action sequel would ship worldwide in June, with a confirmed North American June 3 release date for the Xbox 360 exclusive. After showing off a new, never before seen level from Ninja Gaiden II, Itagaki and his translator announced the date, as well as a new feature.
Like Halo 3 and Skate, Ninja Gaiden II owners will be able to record their ninjitsu performances directly to the Xbox 360 hard drive, then upload them for the community to watch.
