There is an Extra-op bonus mission that is unlocked by finding and acquiring all nine of the XOF Insignia Patches located within the Ground Zeroes mission. These Extra-Ops differ depending on which platform you are playing the game on. PlayStation 3 or PlayStation 4 players will be able to play the Déjà Vu Extra-Op, whilst gamers playing on the Xbox 360 or Xbox One are entitled to try out the Jamias Vu mission.

Both of these missions are fairly short and simple (and hopefully will be released as DLC cross-platform!) and once you get the hang of them will be pushovers when it comes to earning those elusive S-Ranks.

Below you’ll find walkthroughs to both.
