The SMI is designed as an all-in-one device for the player and is important to use in order to launch campaign missions and cooperative missions for both Sam Fisher and Isaac Briggs. The player can even access the multiplayer mode, Spies vs Mercs, from the SMI menu as well as keep track of challenges, unlocks, and progression status using the navigation menu. In Tom Clancy's Splinter Cell: Blacklist, the SMI acts as the player's main menu (or rather 'hub') to do everything in the game, making it a vital and important feature.
