New FPS Game from nothing, I need tutorial video

I want to start a shooting game first but without anything in the project. Is there any good video that shows the important first few things to do for a shooter game. How to create character with custom specifications and set the camera, setting movements and camera rotations torugh mouse
also very important thing i dont know is how to create block values for different objects, If i start a project with content I have - block all, character only, block actor etc, I expect these things to miss inside new blank project

edit: also main menu and how to export the game when its finished

I have a problem inside one of my current projects when I press Play I need to after this click Posses to start controlling the character and it was not like this before. Is this going to be a problem when I try to export the game into a .exe?
