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
Very excited for you to take on the Sierra Madre! It’s a pretty divisive DLC, people either really love it or really hate it. I personally really enjoyed it, but there are certainly parts of it where I can see how they’d make some people dislike it.
