The release for Germany was given as February 21st 2013, and there has been no official word on the North American or UK release dates, although they will probably be within the same week.
The announcement is joined by an exclusive trailer that showcases a lot of the footage that we saw at E3 earlier this year. Towards the end however, it would appear that Raiden will be joined on his quest to some degree by a cyborg-canine companion. Perhaps this was inspired by the Metal Gear companion from Metal Gear Solid 4. Check it out below.
