I haven't opened ONE of the free packs I've collected in Halo Wars 2 since the game was released.
Halo Wars 2 is great. I love it, I'm on my way to level 50. Since the game was released I have completely skipped playing Blitz. I haven't played once. The last time was during the Blitz Beta earlier this year. In Halo Wars 2, you get card packs for just playing the game (mulitplayer, campaign, blitz, etc). You can buy them too, but you can also earn them. That's nice. I've earned over 99+ regular packs, including all the special packs for playing in the beta, Forge and even Kinsano packs will be included in this mass opening.
One thing I'd like to note. I made this video the DAY Kinsano was released. PRO-TIP if you're a Blitz player and are waiting for a specific character, then HOLD your packs. I was getting Kinsano cards immediately throughout out all the packs.
Please let me know what you think in the comments below. If you are playing the Halo Wars 2, hmu on XBL. Don't be a Jimmy!
