Splinter Cell: Blacklist | COOP | Missile Plant | Ghost Mastery | Perfectionist

This is a stealth walkthrough on the hardest difficulty 4E Missions, or 4th Echelon Missions, are a new feature introduced in Tom Clancy's Splinter Cell: Blacklist. This mode, reminiscent of Splinter Cell: Conviction's Deniable Ops mode, allows players to earn additional currency by completing missions given to the player by Fourth Echelon members or captives aboard the C-147B Paladin. These missions, for all intents and purposes, work as side missions that can be played either alone (solo) or with a friend (co-op), either via Split-Screen or online though Xbox Live or PlayStation Network. As the main Co-Op Story, Briggs Missions can only be played with two people. Sam Fisher and Isaac Briggs work together to stop a rogue division of the agency VORON, from Splinter Cell Conviction. Briggs Missions focus on all three Ghost, Panther, and Assault playstyles. Some sections are more Ghost-focused, where the player must not be detected or use only non-lethal force, while other sections have enemies swarm your position, but it is up to you how to deal with them. Players can perform the missions undetected and non-lethal, striking from the shadows, or going into full-on combat. There are also some forced action moments, particularly at the end of the missions. Completing all four Briggs Missions unlocks the Revenant Suit for purchase, the second Voron suit you can unlock aside from the Raven Suit.
