Z-040 Attenuation Field Generator/Localized

The Z-040 Attenuation Field Generator, more commonly known as a Pulse Grenade, is a usable Promethean Forerunner Grenade appearing in Halo 4 which generates a spherical area of effect upon contact that slows vehicles and drains shields and health (similar to the EMP effect of the Power Drain). It is ideal for clearing enemies from cover and can potentially reshape the layout of a battle. When killed by a Pulse Grenade, the target will sometimes disintegrate into orange particles of energy.

Trivia

 * Unlike previous grenades, the Pulse Genade is a roughly diamond shaped grenade.
 * In multiplayer, unless you equip the grenadier specialization (which in that case you spawn with two), you only spawn with one of these grenades. This is in contrast to the fragmentation and plasma grenades, where you spawn with two by default and three with the grenadier specialization.
 * Some of the most effective uses of this grenade include blocking off areas and spraying at enemies in the grenade.
