Syphon Filter 2 (PS1): Mission 4: I-70 Mountain Bridge
This mission isn't too bad, part stealth and action.
Note: Unlike Syphon Filter 1, you do not need to hit headshots with shooting the Sniper Rifle as long as they don't have Flak Jackets. But, you must hit them in the body... as I clearly demonstrated what not to do. Oh well.
