The Elite Adrenaline Suit is a uniform worn by Mercenaries in the multplayer mode of Tom Clancy's Splinter Cell: Blacklist. Normally it is unlocked by reaching the last multiplayer rank of 56. It has the same function as the standard Adrenaline Suit. The only difference between the two suits is purely cosmetic.
The Elite Adrenaline Suit can be unlocked at the tie-in website spiesvsmercs.com.
