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
They’re a pain to fight but I love them because of how campy they are
