Dead Space: Extraction

You take this minor detour in Chapter 3.

During chapter 3 you will head over a very dodgy looking bridge, once on the far side and after a small conversation you will have the option of taking one of two paths. Move your cursor over to the left hand side where the weird 'meat' is and press (DS3) / (Move) to choose that path. Be aware that a necromorph will jump down at you asyou reach the end, kill it and hack the door panel by completing the small minigame. Once done successfully you will open the supply closet, this is where you will receive the trophy.

Be aware that there is also a weapon & text log inside this closet that you don't want to miss.
