Firefight Achievements and 1 or 2 Avatar awards
When you play on firefight, do not play online. Go ahead and go to the firefight lobby. And make sure you have an infinite number of rounds, the weapons you want, invurnerability, and all rounds only have Elites. And then you need to put all skulls on. It is going to take awhile put you will get it. Good Luck and give me some thumb ups!!!
