As the title explains, I'm pretty much a noob to the latest methods of playlist boosting in Halo: Reach, particularly Grifball. So I ask you all a question:

How exactly does boosting in Grifball work and what is the most effective method of doing so?

As far as I know it involves four players each with one guest since the max local is 2 players

But I'm clueless as to how to efficiently get kills in a playlist where the only two weapons are a Grav hammer and a sword. I've heard about people taking turns and what not?

I also have a few minor questions like would a mic be essential/is it required (since i don't have a working one)

If anybody could answer this for me I'd greatly appreciate it since Grifball boosting seems to be a greater K/D and cR booster than Rumble Pit or Infection and I really cannot be bothered earning the 220k for Brig.

Thanks
