BR, Magnum, plasma grenade, Promethean Vision, AA efficency, and ammo.
Ammo is helpful for ordinance drops, you also get 6 shots with splaser if you get one. basically max ammo plus a magazine or 2.
Welcome to the forums. I know many girls named Hunter. Don't worry about the sexist jokes and all that, I'll be there to back you up. (I really hate people who break the rules here.)
The campaign is awesome, this new trilogy is focused on Chief's emotions. In Halo 5, we will see how he reacts with cortana being gone.
Stop being a whiny little baby, I bet in H3 you wanted cortana to die in the first place because she always slowed you down.
I thought the Didact exiled himself..
I didn't hate the ending, but from the the campaign and her rampancy getting worse and worse mission by mission. Midnight was the mission that was the worst where she could split apart due to rampancy. Either way, she would've died from rampancy, or saving John. Halo 5 will be mainly probably focused on John's struggle without Cortana.
