The Eliminator is a Military Spec heavy pistol that can drop a Freaker in one shot. Jacob D'Angelo sells it at Wizard Island from Trust level 2. Expect heavy recoil and 9 rounds a magazine.
It is a sidearm with primary-weapon punch. Use it for headshots on humans and Freakers, or to finish off a stunned Breaker. Recoil makes fast follow-up shots hard.
The PDW holds 20 rounds and fires faster with less recoil. The Sheriff hits about as hard but reloads slowly. Choose the Eliminator when one-shot kills matter more than ammo count.
