Sam Fisher is back and better than EVER! Execution shots and weapon upgrades really make this game worth buying. The story is awesome and there are more ways to sneak around from place to place. The "last known position" feature in this game is very cool and your enemies continue to shoot where you were even though you may have moved. This leaves time for you to flank them and shoot them in the back. Splinter Cell Conviction has great new features while keeping the gadgets form the previous game. If you are into the Splinter Cell games then this game is a MUST BUY!
