At the very start of expedition, when you go down to the first floor under the mutie refuge (West Storage Depot), I recall the body where you can take phil bridges arm being behind a door that is stuck shut. Just now on this playthrough, the door is actually a lockpicking 0 lock. So I unlocked it and I immediately have his arm, skipping the entire dungeon. I will now engage in doing this dungeon backwards, just to see how it goes.
