Tom Clancy's Splinter Cell Conviction (Xbox 360) - Used

Conviction doesn't just re-invent the Splinter Cell franchise. It threatens to redefine the entire stealth-action genre with revolutionary new gameplay mechanics! Sam Fisher is now a rogue agent, betrayed by his former agency. You'll work outside the law to prevent a terrorist attack, and you'll do it in all-new ways with a Mark and Execute System. Lurk in the shadows and mark your target. Then burst from the darkness with a flurry of bullets, eliminate your enemies, and disappear again. If you're spotted, work back to cover using a Last Known Position System, a ghostly outline that marks your last location in the eyes of your enemies.
