Making more atmospheric echos.
Just some examples.

So certain areas have security checks that for weapons and the like.

One in particular irks me slight because it doesn't show anything unless you try to walk out the door then it says something is going on.

Why not throw an echo to show yourself being scanned, it would keep things more themely and more ic.

What I meant was that if someone added an actual echo of the scan beginning and ending, it would be more enthralling then just getting a generic message when you try to walk out the door.
