Mission 13: G.A.R.M.
[MISSABLE TROPHY / ACHIEVEMENT]
Right after the mission starts you go up a ladder and reach the drill room. You must put a biocell into the drill console. If you dont have a biocell you can find one at the end of the hallway on the office desk (only 20 meters/yards from the drill console).
Now do the following:

1) Press left-button on drill console (will move the drill)
2) In the conversation the best option is Scold (doesnt really matter, but if you mess it up enemies will enter the room)
3) Up-Button on drill console
4) Up-Button again on drill console
5) Right-Button on drill console
6) Activate red console button and youre done

The core drill will now open a new optional path for you. The trophy unlocks immediately while you are still at the console.
