Yeah I'm right in the middle of Far Harbor and loving it. Nuclear storms are creepy on the commonwealth, but it's nothin compared to a nuclear storm, in the middle of the fog, on the island. Really really creepy. The story is good so far, no faction seem to be straight forward, I'm fairly certain they have hidden motives all around which really make me doubt all I do. And the enemies are really tough, nothing has been easy so far, despite being level 77, in fully upgraded X-01, and with enough fire power to bring down a whole city.
Thats still one of my issue though, some weapons are clearly underpowered, like the 50 cal and the minigun. I had trouble wiping out a big pack of ghouls with it when it should just shred through them and leaving nothing behind ! That and the power armor should protect you completely from damage until a piece is broken, then you should start taking damage. Hoping for a mod like that coming to the ps4 one day.
