iXi Gaming presents a JFKES creation:
Halo Reach MythBusters
This is the first of many to come so be on the lookout for more episodes to be released once the Halo Reach media gets rollin’!
-Disclaimer-
There are a few mistakes/typos that weren’t gotten around to edit, so forgive JFKES for that.
Hmm. What can I say about myself? I DO IT ALL! ;p But aside from that, I love video games, movies, the good in people and I just appreciate life. So why don't we just hug and get along? 
You really should’ve used the term “Plausible” on the grenade launcher and “Reach will be amazing” myths. You can’t prove that there will be a grenade launcher in Reach by observing an aesthetic on armor. You also can’t prove a game will be amazing by its cutscenes. Just wait for some gameplay.
