Prime Darts are an ammo type for the longneck rifle. They are the ultimate tranq darts a survivor can acquire, but they are quite difficult to get. The engram for the prime darts is unlocked by killing an Alpha Predator from the mod, and the darts themselves also require alpha blood. However, it is definitly worth it. They are 3x as powerful as Shocking Tranquilizer Darts, and can also be fired underwater.

Comes with 250 rounds
