Playing on the hardest difficulty in which there are plenty of legendary mobs that one shot you, normal mobs take forever to kill and if you are out of fuel in your power suit, gl hf.
So many things to explore, around every corner there is something cool. Just feels weird mashing so many bullets into somethings head and it never dies. Highly recommend not using fast travel too much, since afaik there are random events that occur on roads and such.
