UPDATE: Metal Gear Solid 5: Ground Zeroes launches in Europe on 20th March 2014, Konami has announced.
The prequel to Metal Gear Solid 5: The Phantom Pain will be sold in shops on current generation systems for £29.99 or as a download for £19.99. Digital versions for PlayStation 4 and Xbox One cost £29.99.
ORIGINAL STORY: The PlayStation versions of Metal Gear Solid 5: Ground Zeroes have exclusive content. Now, so do the Xbox versions.
The video, below, announced the "Jamais Vu" mission, which is exclusive to the Xbox 360 and Xbox One versions of the Metal Gear Solid 5 prologue.
In it, you play cyborg ninja Raiden (star of Metal Gear Solid 2 and the recent spin-off Metal Gear Rising Revengeance) and battle enemy body snatchers in a base. Raiden is a cyborg, see, so the body snatchers can't snatch his body.
Meanwhile, it appears we have a release date for Ground Zeroes. The trailer ends by revealing the game launches on Xbox 360 and Xbox One on 18th March 2014.
