The YK32 Pulse Pistol is an electrical pulse weapon that was developed by the Yuma Flats Energy Consortium. Though powerful, the YK32 was never considered a practical weapon due to its inefficient energy usage and bulky design. The YK42B Pulse Rifle is a similar, but more advanced weapon.”
Sporting a bulky design, it is an oval shaped weapon that fires a small energy bolt from a red cone tip.
You need to complete the Newton mission to unlock this weapon. It is possible you also need to complete the optional objective there, which consists in taking a prototype of pulse gun. Then the weapon becomes available in several bunkers, including Bunker Delta and Bunker Epsilon.
