I am level 43 and I have 60 hrs on my game save and things are getting really serious lol. I am running into Super Mutant Behemoths, raiders in full armor and power armor, Bother of Steel is attacking me from the air, and Murloc Queens lol. Its got me to the point to where I have fear in the game now which is very nice. I plan on leveling to level 75, and I can't wait to see how hard/scary the mobs are at 75 lol!
