I had a chance to go hands-on with Halo Wars 2 at a recent Microsoft preview event, and there I played the new Blitz Mode. Blitz Mode offers elements of Survival, Domination, and Trading Card games in an interesting twist of players spending a different currency from the main game to call down units. You can only pick from one of four available at a time, before that unit is replaced in your “hand” with one of 12 cards in your “deck”. It’s a fast and frantic mode that offers unique gameplay for the RTS genre. Halo Wars 2 will be available on Xbox One and PC on February 21.
