Honestly, think Boone but slightly more evil. Not full blown "blow up megaton" evil, but still not a nice guy. Modeled loosely after me, probably a wanderer with a few hideouts set up around often traveled places. Probably named "Ralph". I almost always have at least one playthrough named Ralph in Fallout games. Not much to it.
Wow, I didn't know about the existence of such a tool! Thanks for sharing it here.
It seems like balance is going to be a vital part of the game if people want to try and experience the whole thing in a single playthrough, though I doubt that's possible. For my first character, he'll likely have similar stats to te setup you showed us, though with less luck and more agility/endurance or strength.
What do you mean by mechanic? Like some Kinect stuff? (I really don't know a lot about Kinect, except that it works for Just Dance)
If I'm not mistaken, in Alien: Isolation (great game btw) if you make noises, like talking, near the device, be it Kinect or something similar, you can be detected by the Alien or other enemies.
Couldn't tell ya. I know it sounds weird to say "certain weapons", but with the weapon crafting thing, it's hard to say what specific attribute will attach the breathing mechanic. Could be anything with an x magnifcation scope. Could be any non-automatic rifle. Or it could just be snipers XD
