The game is Fallout New Vegas. I’m going to mark this I beat Old World Blues today. I fought the giant robo-scorpion (I had to use up all my grenades left over from the death claw quarry to do it). I ended up lying and saying I was Mobius in order to beat it peacefully. I think for now I’m going to scavenge Stimpaks and other supplies before heading onto The Sierra Madre
One of my favorite things about this DLC is how they made the legendary bloatfly be one of the toughest enemies to kill. This bug has double the HP of the legendary deathclaw and can one shot you if you go in unprepared. I love this game so much.
