How is the North American release of the game different from the Japanese version?
Aside from the usual translation-related changes, several major and cosmetic alterations will be made to DC for its English-language release. The most significant change will be the conversion of the online missions to a set of forty unlockable “extra hard” single-player missions; this is being done due to the poor performance (in North America) of PlayOnline. Other changes include a faster running pace for Vincent (more specifically, 1.2 times faster), less of a slowdown when in aiming mode, new double-jump and dash moves, the ability to perform shooting attacks and melee combos in midair, and limit break implementation via special items as opposed to MP. In addtion, the “easy” difficulty mode has been eliminated, and special features (such as artwork and character models) are unlockable by playing the “extra hard” mode.
