Halo Wars 2 is officially releasing on Xbox One and Windows 10 PC tomorrow, but those who bought the Ultimate Edition have been able to play since last Friday. One of the major new features in the game is new multiplayer mode Blitz, which is a hugely entertaining way to play the game (for more info head this way and check out our review). We've been playing the mode extensively here at the GR office, and in this video we totally smash our opponents in a 3v3 match. We also opened ten booster packs to show you how that part of the game works. Check it out below.
