Why? I like the music in SP but when sitting in the menus it get’s rather repetitive. Also, I noticed there was auto-aim in single player with no way to turn it off. Unless I missed these options, they should be added.
You can turn the volume down for the music. For the auto aim, no, you can’t turn it off. However, auto aim assist varies with certain weapons.
Aim-assist is on all console FPSs, even the ones that allow you to turn it ‘off’; you can’t turn it off completely, it’s always there in the background. The interface (controller) is just not suitable for precise aiming, and until you’ve experienced a better method you won’t realise this clearly.
