Hit indicator like the one you have in HL.
This way you could easily know from which direction you are being shot.
I thought of this when I was playing CS:S without sound, which actually was easier than with sound, you won't get distracted by any sound.. it was really relaxed and you could concentrate on what was happening on the screen. The only downside was that you couldn't hear from where you were being shot.
But even with sound you can't always tell, especially as the positional audio sucks.
