Crossplay One and 360?

Hey so I actually wondered about the Definitive Editions multiplayer, and that was answered, and I’m fine with that but since Co-op still exists, do you think that someone who plays the Definitive Edition on Xbox One, could co-op the campaign with someone who is playing the regular version on the 360? Or someone emulating it through backwards compatibility? The
Multiplayer lack has been answered, but for me I got a buddy who I might get my code for the Halo Wars DE so that I can use my 360 version. Do you think the graphics upgrade would prevent crossplay between the two consoles?

No, that is not possible with the DE. You need to have The 360 version to play the game with anyone on the 360.

I mean the original Halo wars is backwards compatible, however I have 2 copies of Halo wars on my console. In an ideal situation, yes, it should work. However there would be too many problems.

Ye i had to buy digital for it to work.
