What is your favorite grenade and why?
I like the pulse grenade because it useful in tight situations.
plasma
Plasma, I guess.
All time: Spike
Halo 4: Plasma
No love for the good ole fashioned frag? Ok. The finer things in game take some time to sink in…
Plasma 
Wheres the Spike and Flame Grenade!?!?!
All time Spike,But good ol plasmy.
wish the fire grenades would come back…
The Pulse Grenades seem cool and all, but nothing beats Stickies!
Good ol Firebomb. Jk Frag all the way, still have to try the pulse out though.
Mini-nukes er… I mean Frag grenades.
My favorite 'nade from all the Halo games is the Incindeary Grenade (or the Firebomb as I call it) and the classic Plasma Grenade. My favorite out of Halo 4 would be between the Pulse Grenade for being interesting to see and the Plasma Grenade.
Plasma. Sticking people in the face is always fun.
It’s a tough choice between frags and plasmas, both are so useful when used well…but i’ll go with plasmas because sticking is tons of fun.
Frag, of course.
Frags
