OK so sorry if this has been said (I haven't been on here in a while...) but in the x-play video for hardcoe/traits/perks and all that jazz, I saw on the test thing where you choose your skills a new skill called "Nerve". It's at about 1:18 and its at the bottom right and it says "Skills Affected" then the last one is "Nerve".
Was this in FO1 and FO2 or is this a whole new thing?
Also...
1:51 = Awsome machine gun iron sights of doom shooting flaming raiders FTW.
