There is, but not for that knife, they have there own fighting style and the knife is just included in it, but all you do is point and push a botton for the knife to shot out, and even tho it shoots fast it will not kill you unless your are hit in the neck with it.
Primary-FN SCAR-H (for general purpose) with ELCAN sight
Secondary-beretta m9a1 (mag capacity and accuracy)
Special-EGLM grenade launcher under the SCAR firing ME1 Mercury rounds (before you yell at me about grenades not being effective against zombies, let me tell you these puppies have twice the blast radius of regular 40mm regardless of shrapnel these tings will be effective)
GOTH weapon (the weapon I go to when all other weapons fail me)-dual glock 18s with pistol bayonets, yes they make those
