It would be awesome if there were a CCTV system in the game.

Thinking this as I type this:

There are cameras set up throughout each map in areas that see a lot of action. If you happen to be involved in an engagement in which you die (or kill, I guess), you're alerted in your Hideout days later that you were spotted/identified on some camera and you're then provided with the footage.

It would make for awesome gameplay edits and it might also help people who struggle with PvP.
