Quick note - I searched the forums for a Halo thread and found relaxing video game music instead. Good thread, but not what I'm after. If there is an up-to-date Halo thread, just go and close this please.
I'm one of only four friends (out of the former twenty-one of us) who are still clinging on to Halo, and so I've been following it because the people who'd dump info on me have left for other games now. And just recently some Halo 5 news was dropped. Here's some stuff that Game Informer released today:
Chief is joined for the first time in-game by Blue Team, the legendary Spartan squad from the books.
Locke has his own team of Spartan IV's and one ODST (who happens to be Nathan Fillion!)
Locke's team is called "OSIRIS"
Blue Team are declared AWOL
Blue Team (and probably Osiris, too) can be commanded by the player in-game.
In co-op campaign, everyone picks the character they play as, each with a unique loadout.
I'm excited, to be frank. I love the characters and it's awesome to see them in-game at last. Plus I like the twists to co-op, and I'll be buying my own Xbox One in September (wisely spending my finance payment) to play rather than hijacking my flatmate's every day.
