In order to answer your question as to why Hunters die to a single Pistol shot to the back, I will explain:

First an foremost, you have to realize that Hunters are giant colonies of orange worms. Yes, you heard correctly, worms.
Next, the armor of the hunters and their shields are made of the same material as the Covenant flagships (Thus extremely durable.)
Now, to get to the main point: Why Hunters die to a single Pistol/Sniper Shot.

When you fire the high-caliber, high-velocity rounds, they tear through the worm colonies and hit the armor from the inside. The velocity causes the rounds to recochet multiple times, shreding the colony. Eventually, there are too few worms left to hold the Hunter's armor's weight and the last of the colony is crushed by the 2-3 ton armor.

I hope that you have been informed ^_^

Now, I must watch you escape from the building where the Silent Cartographer is. So far, your "Ragequits" have been most humerous :P

Just letting you know that, although I have not had the chance to see your first update, I will once I get a 32:06 Minute break between Studing and taking tests/Finals for college.

I personally cannot wait ^_^

sure that's cool!

Gotcha! Feraligatr good for you?

Ima be your starter K? >:D

The sniper level where you tell everyone that Night Vision is BAD. The one level where Hunters are first introduced.

Lol what sniper one? There's a LOT of videos I use sniper rifles in throughout the game. Anyway, I'm glad that you're enjoying it! It's nice to know that at least one person is watching my videos!

No worry about MY interest drying up. I check your channel every day waiting for the videos.

In the mean time, I watch one Halo vid a day. Up to the sniper one right now.

haha, as a broke college student, I don't have the money for Halo4 >_>

However, Halo Reach is keeping me satisfied at this moment. I've also started a Nuzlocke Roulette. MVP is currently a Magcargo. NU my rear. He's saved my hide more times than not and will instrumental to Lenora's defeat O_o

thanks it's good to hear that (on both counts :P)

I just got Halo 4 so I might be a little late getting out my Emerald videos. Can't put it down lol.
