Co-op mode (Batman: Arkham Knight)

You said that there will be no multiplayer, only a story game, why don't you make a story game without the Internet, for example, on a PC, one on the keyboard with a mouse, and the other on a joystick with analogues, one plays Batman and the other Robin, the screen is divided in two, and you can play freely, the player passes the mission and you can intervene calmly and leave safely, you said that there will be no downloads, such as the entrance to the building or the flight of the streets, I think it will be the most normal, Robin will have a motorcycle))) well, Nightwing will chan such, too, how is this idea for you ????? think if that. you are doing the current plot, I think many will like this idea.
