The final S.P.E.C.I.A.L. video is out and it involves Luck. Luck has been a big part of the Fallout series and I'm sure it'll play a big role in Fallout 4 as well.
I've replayed my Fallout games pushing very high luck to much success and you can even see that in the Fallout 4 demo from E3, they maxed out the luck attribute as well. Luck can really turn your game around and who doesn't like getting visits from the mysterious stranger.
Fallout 4 is due out in just a few short weeks, so check out the last video in the series and start getting hyped up for the game.
