Many favorite moments. The first time completing each campaign, finding out Halo Wars was a great multiplayer game and having some really tense matches there, playing with my friends offline or online. Just great.
Being stuck on a team where my teamates quit.
I hate the BR, and DMR. They're cheap weapons that take no skill to use. EVA is my favorite helmet. The Assault Rifle is my favorite weapon. It's just a well balanced gun that needs you to make every bullet count.
