Ninja Gaiden Sigma Plus hitting the Vita next Feb

That's the Japanese launch date, so not certain it will hit the western launch, although the game is pretty much done, so could hit at the same time. It features a new "hero" mode and adds touch controls, but is basically the game you know and love in a slightly new wrapping.

It will feature slightly smaller bite-sized level design to allow for gaming on the go and the rear touch panel can be used to charge up moves.
