Halo Wars 2

Blitz, the card-based, fast-paced, online strategy mode in Halo Wars 2, can be played 2v2 or 3v3.

Accessed via the Main Menu by opening the "Blitz" tab, you will be able to inspect/build your card decks and even buy additional Card Packs should it strike your fancy. When building your twelve-card deck, it's important to choose cards that cover both offensive and defensive capabilities. Once your deck is set, go ahead and find a match of your preferred setup (3v3 is probably the best option for this achievement).

In order to win a match of Blitz, you will need to capture and hold two of three Zones in order to score points; the first team to score 200 points will win the match. During matches, Energy Pods will periodically be dropped around the map. When destroyed, these Pods will spill three Energy Crates. It is extremely important that you and your teammates collect these Energy Crates since cards can only be played with Energy!

In recap, you only need to hold at least two Zones in order to score points. While holding a third Zone increases the rate of points earned, it's better to focus on fortifying and defending only two. Communicate with your teammates, recycle cards that you don't need, and play strategically in order to defeat the opposition and unlock the achievement.
