This game is rock solid at parts.
Ended up trying to take the minutemans castle back, it's guarded by a mirelurk queen, bitch is hard as nails, spent a good hour ducking and diving getting off as many shots as I can and only have her down to about 75% health . Need to find a fat man and come back me thinks.
The suicide supermutants are actually a big help, just VATS the arm with the bomb attached and watch everything near get blown up.
