I have been thoroughly impressed by this game but I have found that the Heads Up Display can be cumbersome when trying to focus on what's directly in front of me.
A Ghost-Only HUD option seems a quick ticket to completely rectify the situation.
#1. The HUD only appears when the Ghost is activated
#2: Have a hot-key button to adjust the HUD while it (Ghost) is activated to skirt and skip loading times for pressing start and accessing the menu just to switch in-between HUD modes.
#3: Just take the crosshair off please.
Quicker acquisition of objectives.
Ghost becomes a more immersive tool.
Nothing in the way, ever.
Working to put in the effort
