One of the biggest things my friend hates about Halo 5 small but can hurt you is that there is no radar when aiming with scoped weapons. Your area of vision is already reduced when aiming so should there be a radar to kinda warn you if danger is coming in any direction. Personally i wouldn’t mind having one but not a huge deal that there isn’t one.
No, be aware of your surroundings
Never has been, never should be!
