or is this new guy Agent Locke the new protagonist?
I imagine it is going to be a mixture of both, like in Halo 2. Two campaigns that eventually intersect.
Of course he’s playable! It’ll be like the Halo 2 campaign more than likely. Just like the guy above me said.
I also imagine it to be more like halo 2, I just hope that we get to play as the Arbiter in some points in Singleplayer, not Co-Op only. I want my Elites to be recognized and to be able to be played as.
I almost envision a triple campaign to be completely honest. Playing as Locke, Chief and Arbiter all the same.
That would be extremely nice~
Whoa, Ghost of War, that’d be crazy! I wouldnt be opposed to playing as all three…just as long as the campaign is long enough to give each character (mainly John) a suitable amount of play time.
You know, the three character plot may not be all that unlikely. We’d play as the Chief on his journey to do whatever it is he’s doing, and then Locke as he searches for him. Finally, the Arbiter would remain on his homeworld, fighting the Flood.

Now that is something I’d like to see.
Why not both?
Dual-Campaign, Halo 2-style!!

Personally, if we only stepped into the shoes of Agent Locke, I wouldn’t be upset. Granted that isn’t a likely proposition as we still have much to learn about Chief and see him develop.

I wouldn’t be surprised if can also play as the Arbiter.
I find it very Interesting that this ONI spartan “Locke” is seeking advice from the Arbiter to find John.
