A problem I have with the game is that later in the game and I personally think the game should feature a higher damage output.
However, I also understand that this could make the game a bit unrealistic. Thus I have a suggestion that could both ad realism and force players to be more strategic: magazines.
Currently, players can press the reload button and get a full magazine every time. What if magazines were a finite resource? So when you start the game, you have two magazines for the Möller and if you empty them, you need to reload them. If you reload over and over until you run out of full mags, you’ll reload to the “fullest” available magazine.
IMO, this would enable the developers to increase damage output significantly and still decide at which pace players progress.
