This is merely an idea, some may think it is stupid and some may think it is a good idea, but however you put it, this is just an idea and i am not asking someone to take their time to make it.
Although: If you make it please credit me for the idea
Advantages-See enemies trying to sneak up on you and even make chams work for the mirror
Disadvantage-Lose a tiny bit of game window, but for a great cause
This is an image of what is exactly behind me, please post your comments on this idea and don't forget, please credit me for idea IF you use this idea..
I was sitting there this morning, drinking my coffee and smokin' a cigarette. I started up CA and actually found myself thinking about this, since I move (physically and mentally) slow in the morning. Damn, this is something worth doing.
EDIT: Ryguy's comment: or over the map, I don't ever use it, Does anyone???
It would be too distracting and take up too much room.
Sounds like a good idea, until you started looking behind you and get shot from upfront.
I think it would work more like a rearview mirror in any racing game. You can actually view what's ahead of you and the rearview mirror without focusing too much on either one. And if your using chams, then it would be hard to miss a bright blue/green/orange guy coming into picture.
But maybe only bring up a rearview when pressing and holding an assigned key? If your camping in a search and destroy, it could help with watching two places at once.
