Responding to the leak
As you begin the game, you'll be given the option to choose your Junior Deputy's gender. Note that your choice is final and you will not be able to change this at any point in the game. This is merely a cosmetic choice so feel free to choose how you wish to be percieved in the game.
After the opening cutscene, you'll find yourself on the helicopter heading towards Joseph Seed's compound. There's not much you can do other than proceeding forward so begin the slow walk towards the imposing church.
After the cutscene, handcuff Joseph Seed and proceed out of the Church where you'll be greeted by more of the residents. Ignore the hostilites and continue towards the church where all hell will break loose and end this short, interactive mission.
