Richard Carillo, lead game designer of co-op on Splinter Cell: Blacklist, stars in a new developer diary that explains how different characters will change the way co-op missions are played.

Carillo introduces us to some mission types that are geared toward a specific playstyle, depending on Sam Fisher's chosen partner.

For example, Grim's missions focus on stealth because she's oldschool and prefers a Ghost-type approach to accomplishing her goals. You'll have to be sneaky and remain undetected, or else you'll be forced to restart the mission.

Newcomer Isaac Briggs is an ex-CIA agent and Fisher's main partner throughout the co-op narrative. This means that you'll get to utilize all three of the game's playstyles (Ghost, Panther, and Assault), during your missions with him.

Carillo also says that the co-op mode will require both players to work together and that the game is designed so that one player won't have to carry the missions.

Watch the developer diary above and let us know your thoughts on the game. Will you buddy up with a friend to take down terrorists? Sound off in the comments.

The game will be released on August 20th, 2013 for PC, PlayStation 3, and Xbox 360.
