seems to me you have found every way to drain cash from your player base, with no real understanding of game development. you have 15 lines of DLC and 3 lines of “detailed story”. you’re making a generic shooter with no unique concepts and game play. you are massively over reaching what is possible in a game engine, you cannot just say “i will have photo realistic graphics” “i will have real world physics”. have you seen how much processing power you need for real world physics simulation? how much gpu power you would need to have real time photo realistic graphics? sorry to say this is not a game idea, this is a money making pipe dream that will never work.
