So I just completed the first quest "Death From Above" and stared the second one "Shock Value". I just got the Deathclaw Control Scrambler and decided, before heading to the Olney Powerworks, that I'd fast travel to Megaton to sell some of the stuff I'd picked up at Moira's. So I get to Megaton and start heading up the ramp on the right when I hear shooting behind me. I turn around and there's about five Megaton settlers shooting at this Deathclaw! They managed to take it down and I think only one megaton settler lost his life.
It was such a random moment and, I know it's most probably Fallout being Fallout and glitchy, made me think about how life in the wasteland would be. Anyway, I've attached a picture below of the dead Deathclaw in Megaton if you'd like to take a look! Just thought I'd post this here.
