*Missable*
I actually managed to do this without trying. Just be sure to enter every cabin you come across (taking your time at the beginning to explore and visit the cabins before heading to the canteen), and by the time you reach the flooded cabins towards the end of the game, this should unlock. Make sure you swim between them via the vents, or go up and over through the ceiling shafts. Easier said than done, as you're being pursued during this bit, but you should be fine to explore each cabin without being hassled. There are eleven cabins to visit in total.

PS Don't forget, once you get to Roy's cabin, there will be Roy's spoon on the chair behind you, which you need to look at for another trophy/achievement.
