Let the player decide what they want and what they don’t want to see. Example: The blue triangles of the allies, ‘‘V to mark enemy’’ or ‘‘hold your breath’’
Some things are quite useful when playing, such as the mini map or the squad interface. But this circle showing the seconds my soldier needs to drink water I really see it quite expendable.
In addition to this, there would also be the issue of ammunition. In normal mode the ammunition is always visible, but in minimalist mode it is not seen at all. I suggest that you allow the player to choose between seeing the ammo always, when you change soldiers for a brief second, when you reload, or not seeing it at all.
