Halo Wars 2 was confirmed at Gamescon 2015, and was released Fall 2016 for Xbox One and Windows 10 platforms.

Gamescon 2015 Teaser Trailer
In the teaser trailer, a Spartan is being dragged by another Spartan away from what is assumed to be Brutes, most likely a Brute Cheiftain. The Spartan radios in, "Command, this is Red Team. Something hit us, Douglas is down. Immediate evac. requested."

The Spartan being dragged fires at an unknown enemy, assumed to be brutes. The Spartan is most likely Douglas-042, due to the right shoulder patch emblem uniquely matching Douglas' armor, unlike what Jerome-092 and Alice-130 have.
