I've been playing Far Cry 5 on Xbox one for a few days now. I find the game confusing. The aiming aid e.g. Only seems to work sometimes. I'm shooting around wildly in the area, but an opponent is not targeted. Some missions seem to me almost impossible at the beginning but still I should do that. Is there somewhere the option to see the game progress?
No you can't.
You can see the game progress in the main menu as a percentage. Honestly, I can't handle shooters on consoles. On the PC, the headshots are pleasant to the touch.
Take cover and position yourself well. Then you have it easier.
