As you may know the Crysis 3 hunter edition comes with 1 of 3 dlc in some stores:

Stalker Pack – Includes the base game, all Hunter Edition content and the following early multiplayer unlocks: for players who like to stalk their prey from the shadows the Stalker Pack provides early multiplayer access to the deadly semi-auto Jackal shotgun. This powerful, close-range shotgun comes with a unique silencer attachment, custom weapon skin and two exclusive themed in-game dog tags.

Overkill Pack – Includes the base game, all Hunter Edition content and the following early multiplayer unlocks: the Overkill Pack features early multiplayer access to the Typhoon assault weapon and skin. Spewing 500 rounds a second, the Typhoon gives players the ability to go guns blazing to take back the Liberty Dome. Also included are two exclusive Overkill themed in-game dog tags.

Predator Pack – Includes the base game, all the Hunter Edition content and the following early multiplayer unlocks: the Predator Pack delivers early multiplayer access to the Feline submachine gun and exclusive camo. With an extremely fast rate of fire and a 60 round magazine the Feline is highly effective and deadly, at short range.

If you read closely besides camo the Stalker pack has the only useful thing you cant get normally: A unique silencer attachment for an AUTO SHOTGUN.
