Nacrogen requested that I post this with paragraphs so here it is...
What is this new achievement you may ask: Vidmaster Challenge: Annual (0 points) – After 9/25/08, complete Halo on 4-player Legendary LIVE co-op, with Iron, and everyone in Ghosts.
This is a walkthrough on how to get the double double achievements. First off the achievement requirements are simple.Double Double (25 points) – On a Legendary map, get two Double Kills during any ranked or social match. I find it simple to do it two differnt ways.
First off get in a match of Team SWAT on Blackout. Then pick two people from the tower. Then repeat process. Or you can run around with a BR like a crazy maniac which is what I prefer(although the first time I did that I got an Overkill no two duble kills *sadface*).
