I figured quite a few people are looking for one thing or another in game, so maybe a specific thread was in order.
I myself have got both halfs of the safe code (from hermit and the military guy in countryside) - as referenced by Snitch in the bar when you buy info from him, but cannot find the safe it opens. I'm guessing I've either passed it by or its in one of the areas in the North I've yet to explore.
Any hints would be appreciated!
