“POLICE! HANDS IN THE AIR!”
You get to hear that phrase a lot in SWAT 4. You and your squadmates will scream it several dozen times per mission. For once this isn’t because of a very limited number of stock responses a la the Elder Scrolls, and neither is it an amusing audio bug; instead, you want to be announcing your presence as loudly as possible when you enter a room. You want hostages to stay down, you want armed criminals to surrender, and most of all what you don’t want is to shoot a gunman without warning them first, because the SWAT series are the only games I’m aware of that have actual honest-to-god rules of engagement.
