Microsoft talking about the multiplayer, and here is the bit about the Blitz mode.
But the most compelling new mode of play will be Blitz, a hybrid card-collecting and real-time strategy game.
In this mode, players will create decks of 12 from card packs earned by playing through the Halo Wars 2
campaign, as well as daily challenges. Every leader will have access to this shared pool of cards that complement their specific playstyle. Each leader can have up to three different decks, and each card features a unit that you can deploy on the battlefield in real-time throughout the course of the match. All units carry an energy cost: the more powerful the unit, the more expensive they will be to deploy on the field.
Energy can be earned during a match by collecting energy canisters that are dropped during the action, or by defeating enemies. Then it’s just a matter of strategically deploying a unit that is randomly selected from your pre-made deck. Do you spend your energy on smaller units to build up your forces, or do you elect to save your energy to drop a bunch of Wraiths on the battlefield? Maybe you’d prefer to deploy a fleet of Warthogs to speed around the map and cause havoc? Those are the kinds of choices you’ll have to make when playing Blitz.
“What we wanted to do is make this a non-intimidating mode. It was important that if a player wanted just one deck to pick their favorite units, that should be a viable strategy,” explains Oli Smith, Project Lead on Blitz at Creative Assembly. “We didn’t want to start where, ‘For this map I’ll need this deck, and for this mode I’ll have to have this one.’ A lot of the depth comes into the deck building, so we didn’t want to overwhelm people by having too many other variables.”
There will be two variations of the Blitz mode available to players: Firefight and PvP. Firefight will be a wave-based PVE mode, that can be played solo or with up to two friends, against ever-increasingly difficult enemies with the core objective to survive as long as you can and obtain the highest score possible. PvP will have custom ranked and unranked matches that will be 1v1, 2v2, or 3v3 support.
