Flight 1 is doesn't contain much just Tip of the Spear Campaign mission and a few options to change the controls for KB/M and Field of View.
I'm playing with controller because I am awful with the KB/M plus I can't get the controls setup the way I want it. Unfortunately there was no way for me to adjust the sensitivity for the controller so I was stuck with the default.
Also I apologize for my horrid gameplay. I'm no good anymore at Halo and I played it way too safe.
Sorry the Overlay for Afterburner is small too.
