Open World & Co-Op?

Would co-op be able to work in an open-world Halo? And I mean traditional, split-screen, two Chiefs (or Thel) running around like in previous games? I can’t think of any open world first-person games with co-op like that off hand … Destiny, maybe?

What do you guys think? Would it work? Or am I not thinking broadly enough here? Co-op over LIVE or local … would it be the same as before?

A complete open world with split screen - probably not (I’m thinking the limitation here being able to display each environment simultaneously as the limit). An open world co-op with two or more X Box Ones - it should be able to. About the only information that needs to be transferred between the two(+) systems is where the other player is, and what is now done (dead / buttons pressed / locations of objects that move, such as vehicles).
Given you would be playing cooperatively I can imagine that both players would tend to be close to each other, unless the objectives are designed around a simultaneous take down approach (a bit like the three towers in Halo 3, where you have to do towers 1 and 3 - you could actually set that type of objective up as player 1 - tower 1, player 2 the second tower and so on). However, given the environment is “open world” you may actually have both players going off in completely different directions to wherever their favourite cache of weapons / vehicles are in the environment before actually starting whatever the objective is.
And I can’t think of any open world environments like that either.

On the Old Xbox 360, I would of said no, but with the Xbox One, maybe, at least when it comes to split screen, Online CoOp, the Xbox 360 could handle it, the Xbox One on the other hand should be able to handle it. Let’s stop and think, what other games with open world on the Xbox that also have CoOp!? Dead Rising 3?

I would imagine it would be like Borderlands. Borderlands has a semi-open world, I mean the levels are HUGE. I could be fighting bandits on one side of the map while my buddy drives clear to the other side of the map to buy supplies, all local coop.
