So after about 28 hours I finally stumbled into Diamond City. It looked awesome, but I wanna go back during the day to see it really alive. Got a mission from there tracking down some detective. Right as I get to my destination I get attacked by some very large beast who throws rocks and beats on me. I found the Grognak outfit and axe in a certain store and while the axe does less damage than my super sledge, I can get so many more swings off with it per full AP bar (5 vs 2) that I am using it anyway. Then it drops this cool power fist type weapon.
Disappointed with the weak options with mods for melee weapons. It makes a melee character like mine kind of dull at times. Guns get such better mod options, virtually endless.
