“I pray for the safety of all good people who come to Zion. Even Gentiles. But we can't expect God to do all the work. I have been baptized twice; once in water, once in flame. I am the right-hand of the Lord, and the instrument of his vengeance. Zion, may not be lost to us after all.”— Joshua Graham
The trailer shows that the add-on features rain, something never seen in a Fallout game before.
