Hi guys,

This guide will show you in (hopefully) an easy way to achieve the S-Rankings and every achievement for every mission in Ground Zeroes.

Before attempting any of these missions, make sure to go to the Gameplay Options and deactivate Reflex Mode. This will give you some bonus points and points are all that matters for the sweet sweet S-Ranking. It does not matter if you do the missions on normal or hard difficulty since only the S-Ranking matters. Therefore it is recommended to choose normal difficulty.

S-Ranking


Rescue Achievement

S-Ranking & Infiltration Achievement

S-Ranking & Pacifist Achievement

I recommend using the mouse instead of a controller for the sections inside of the helicopter.

Extraction Achievement

Hint: If you carry the prisoner while being attacked by soldiers, it can happen that he dies on your back but you continue to carry him and you can even still put him on the chopper. If the achievement does not unlock for you make sure you try again without being shot at on the way to the helicopter to avoid killing the prisoner.

To unlock the missions Deja-Vu and Jamais Vu you first need to collect all 9 XOF badges and then finish the Ground Zeroes mission.

Reminiscence Achievement

Hidden Achievement

In the video above I almost got this achievement but got caught once at the end. You can use the same strategy as above just making sure you do not get caught in the last fights. It is basically luck and how fast you can deal with the enemies so that they dont detect you.

Unlocked Achievement

For this achievement you need to unlock all trials for all missions. That does not mean that you have to do all the trials, unlocking them is enough for the achievement. The fastest way for this achievement is the following:

1. Play through all missions on normal difficulty.

2. Do the "Fastest Marking of all Enemies" trial for all missions on normal difficulty (except for Intel Operative Rescue):

3. Play through all missions on hard difficulty twice. Playing through them once will unlock the Time Trial and playing through them twice will unlock the missing trials.
