Introduce a hardcore game mode

It would be nice to see a hardcore mode introduced to the game. My only complaint is that it doesn’t matter if you shoot first and in reality it should be a kill shot but because my gun doesn’t fire 100 rounds a second then I’m the one who loses that matchup. I realize it’s not for everyone but I feel it would make the game more tactical and ultimately more realistic. People would have to be more careful and calculating about what they do. Aside from that I love the game as a whole.
