How to unlock the Hidden achievement in Metal Gear Solid V: Ground Zeroes - Definitive Guide
The first Part is quit easy, you must kill / stun 12 Enemies, after this it comes several Waves of Enemies which attacking the Helicopter, simple stay in cover and kill the Snatcher. Dont forget to turn off your Lights on your Weapons!
My Time was 07:25:05 and i earn 26282 Points with an S-Rank
I'd just like to add (in case anybody was wondering), you can kill enemies in reflex mode (when it goes slow-mo, just after you've been spotted) and still get this achievement. I got spotted twice in this manner and still got an S Rank and the Hidden achievement.
To make sure that you aren't spotted, take your time around corners, and spot out enemies with your binoculars as much as possible. Also, make sure to turn off the light on your assault rifle so that you are harder to see in the shadows.
During the final part of the mission, use the RPG to kill enemies in groups, and stay behind cover so that you are not noticed. Once all enemies are taken out, the helicopter will pick you up and the achievement will unlock if you completed the mission without alerts.
See the video below for a walkthrough using this method:
I did it in a little under 16 minutes, 15:49.868 to be exact (+19,318)
Zero combat alerts (+1,200)
1 kill (-600)
Zero retries (+400)
I also used reflex a couple of times so I didn't get that bonus
Just thought I'd give people a bit more insight about the amount of points you need, hope it helps!

Within this Extra Op, you are granted the opportunity to play as Raiden, as he deploys into Camp Omega with the objective of taking out "Body Snatchers" that are posing as standard infantrymen. In order to get this achievement, you will have to refrain from being seen, raising any alarms, or killing the regular guards; although you MUST kill the Body Snatchers with lethal means, either by using your Assault Rifle or lethal CQC. When dealing with regular guards, make sure to use the Wu Silent Pistol.
Since the Body Snatchers look identical to a regular enemy guard, you will need to use your binoculars in order to tag enemies. Regular guards will be marked blue when scanning them with the binoculars, while Body Snatchers are marked in green. Don't worry about hiding their bodies, as they disintegrate after killing them.
Once you have taken out all twelve enemies in Camp Omega, locate the white trailer with the red door in the helipad area right outside the admin building and open it to find a Rocket Launcher inside. Shortly, you will need to kill all of the reinforcements here in order to proceed, but you cannot be seen while doing so. For the second wave of reinforcements - when they are pouring out of the main gate of the admin building in attempt to get to the AA guns - fire your Rocket Launcher at the group to dispose of them quickly.
Below, you can find a video walkthrough for this achievement - paired with an S-rank - which details specific methods in dealing with the final section of this mission.
NOTE: Entering "Reflex Mode" does NOT count as being spotted, so don't worry about restarting your checkpoint if this happens.
Only kill soldiers that have been taken over by a Body-Snatcher, do not kill any of the regular soldiers. Dispose of any regular soldiers with non-lethal means such as the Wu Silent Pistol. You must not alert anyone. You can tell if a Body-Snatcher is inside a soldier or not when marking them. Normally, a soldier has a blueish color when marked, but a Body-Snatcher gives off a greener color.
Immediately after taking care of the 12 enemies, head over to the main gate at the Admin Building and run away from the building straight to the trailer with the locked red door. Open it and you'll find a launcher inside. During the portion of the mission where Body-Snatcher guards spewed out of the gates of the Admin Building, I used the launcher and fired from afar as they ran out. Remember, you must not be seen. Be careful when you happen to enter reflex mode, if you take too long here sometimes the camp will go into full alert for a quick second even if you barely managed to get rid of the enemy that spotted you.
