My favorite part about Killzone 2's multiplayer was hearing the headshot chirp. If you had a sentry gun or air bot and you were on the other side of the map when they got the kill, you don't hear any shots just the chirp.
*edit* or if you hit somebody who was lagging and then like 20 seconds later it goes through and you hear the chirp.
