It is available as a payload for Warfighter and is unlocked by default. It has an extremely fast fire rate, consequently being the weapon with the fastest fire rate in the game.
The Claw shoots ballistic projectiles that can ricochet off of surfaces. Combined with its high fire rate, the Claw is able to quickly dispatch both enemies up front and around corners. In objective game modes, the Claw is useful in severely damaging or hindering players on the objective with the barrage of projectiles.
The Claw is deactivated when all ammunition is spent, when the 30 second timer runs out, or when the player switches weapons. Firing the weapon decreases the amount left on the timer.
