I'm starting over in Survivor Mode. So far, so good. I'm at the Palace Underground with no problems.
And while the main plot is very thin, I love the backstory that you find through newspapers, Dee's, and the Queen's letters. I also love that letter on the ground in front of the manhole in the Safe House. It gives an insight to The Prepper and tells us more about him. He's the most intriguing character in the game by far, and if they made a sequel, I'd like it to take place before and during the outbreak and have us take on the role as the Prepper before he became who he is today.
