This picture shows a member of the Spy team holding a member of the Mercenary team hostage. While you are holding a Mercenary hostage, you can talk to him by holding down the White button. After about 15 seconds, the Mercenary will automatically go unconscious. Before the 15 seconds are up, you can either hit the Right Trigger to knock the Merc unconscious or you can hit the A button to break his neck, which kills him.

  In this picture, Sam Fisher, the lead character in the single-player campaign, is in a jungle-type environment. This level is dangerous because it has tons of trip mines. Each individual blade of grass in this level moves exactly how it would in real life, thanks to a very good physics system.
This is what the aiming system in the game looks like. It consists of 4 arrows that come together as you steady your aim. This is very realistic because in real life, you must steady your aim to pull off an accurate shot.  
  This is what the sniping system in Splinter Cell: Pandora Tomorrow looks like. You have an F2000 M.A.W.S rifle that has a 15X zoom on the scope. This gun is great for pulling off shots from a distance.
This picture shows Sam holding a terrorist hostage. While holding a terrorist hostage, you can either knock him out by using the butt of your pistol or you can interrogate the terrorist to get useful intel, such as pass codes or where a particular person is.
