Former Third Echelon agent Sam Fisher is at the top of his game, but are you? As you play Splinter Cell: Conviction, your actions are constantly graded in a system called P.E.C.: Persistent Elite Challenges. Each challenge has three tiers, with increasing requirements – but also increasing point payouts. The Vanish Challenges test your stealth skills. If you know Sam Fisher, you know he’s all about melting into the shadows, striking without detection and disappearing again before his target’s comrades know what happened. Use the strategies in this video to complete all eight Vanish Challenges: Vanish Silently, Cat and Mouse, Last Known Position, Portable EMP Escape, FlashBang Escape, EMP Grenade Stun, Choke-hold Freedom, Reviving Teammates.
