Sony and Konami have announced that players that pre-order the PS3 version of Metal Gear Solid V: Ground Zeroes via PS Store will receive for free the digital version of Metal Gear Solid: Peace Walker HD. This deal is exclusive to Europe, and doesn't include pre-orders for the PS4 version of the title.
Metal Gear Solid V: Ground Zeroes takes place after the events of Peace Walker, in which players will be able to experience the story of Big Boss while in command of his own military group: Militaires Sans FrontiÃ¨res. Peace Walker was also the title that introduced us to several key characters in the Metal Gear Solid saga.
This offer will be available until the 20th of March.
