These are two gameplay videos just released by Bethesda for Fallout 4. The first is exploration based, and the second, combat. Man, I still remember the first time I ever faced a Deathclaw in Fallout 3. I only had a revolver and two dozen bullets, and those bullets were all for a different gun. It was a massacre.
Keep going for the videos, then let's hold hands and pray there aren't any delays that push the release date back.
