i know im a noob but please can somebody explain the pulse grenade to me? and if anyone went to PAX 2012 did you like halo 4?
Pretty much think of the energy drain from Halo 3, it gradually damages targets within a small area of effect, BUT it then blows up, killing those who are close.
thank you i fourm thanked you 
how do i close topic?
You throw it, it lifts from the area It lands, it does not bounce. It will then levitate and generate a field that disables vehicles and damages you. It will then explore after a bit and deal more damage.
