Z-040 pulse grenade

The Z-040 Attenuation Field Generator/Localized, also known as the Pulse grenade, is a thrown Forerunner weapon that functions similarly to traditional grenades.

Overview
The grenade creates an area of effect that disables vehicles, and damages shields and health. It is designed to clear enemies from cover. Upon being thrown, it forcefully detonates and forms a hazardous ionization sphere which eventually collapses, destroying nearby targets. It is said to be similar in function to the Power drain.

Trivia
The Pulse Grenade will disable Light Bridges when detonated upon one.
