Halo Wars 2 is adding to the Halo canon with the introduction of Atriox. He's a Brute that turned against the Covenant because of their brutal treatment of his people. Unfortunately, he seems to have gone mad somewhere in the process and takes to indiscriminately killing whatever is in his way.

The trailer didn't show anything in the way of gameplay, but it made clear that Atriox is your primary enemy in Halo Wars 2. If you're a fan of the original Halo Wars, and you plan on getting Halo Wars 2, you may want to take a look at the Ultimate Edition. The $79.99 Halo Wars 2 Ultimate Edition comes with the season pass and Halo Wars: Definitive Edition.

Pre-ordering the Ultimate Edition will give you early access to the Definitive Edition on December 20. Halo Wars 2 was previously scheduled for a Fall 2016 release but was delayed to February 21, 2017. The game will be available on Xbox One and Windows PC.

I'm all for new additions to the lore of Halo. However, it's a little implausible that there's some legendary Brute that humanity has somehow never heard of that was able to secretly able to amass an army that could stave off the Covenant at the height of its power. But hey, more Halo is cool.
