This mission basically acts as one giant Easter Egg and a throwback to the original Metal Gear Solid. To complete it, you will need to look at your iDroid and check out the mission information screen. There will be seven photos located here relating to the original game that we will need to re-create by finding a in-game match to them located at various positions around Camp Omega.
Although you only need to find and complete a single scene to open up the exit to complete the mission, if you can find, locate and re-create all seven scenes, you will earn the level’s mission-specific achievement/trophy 'Reminiscence'.
Note: this walkthrough explains how to complete the optional objective for the level-specific achievement/trophy. If you want a faster, more efficient way through the level, check out the ‘S’ Ranking walkthrough below the main guide.
