Konami has lowered the official price for the boxed versions of Metal Gear Solid V: Ground Zeroes on PlayStation 4 and Xbox One. All versions now have a suggested retail price of £19.99/19.99/$19.99, no matter the platform. From the official press release:
As interest continues to escalate for the forthcoming METAL GEAR SOLID V: THE PHANTOM PAIN, the new price-point will allow users to practice their sneaking skills ahead of Hideo Kojima’s next epic adventure. The events in METAL GEAR SOLID V: GROUND ZEROES dovetail directly into events in METAL GEAR SOLID V: THE PHANTOM PAIN. The acclaimed prologue acts as an entry experience and introduces key gameplay components that will be explored in the fifth, full METAL GEAR SOLID epic and as a bridge between the linearity of existing titles and the full open-world environments of METAL GEAR SOLID V: THE PHANTOM PAIN.
