Halo Wars 2

In Blitz matches (Online or Firefight), Energy Pods will be periodically be dropped into the map. If you move any of your units near an Energy Pod, they will begin firing at it until it's destroyed, revealing three smaller, purple Energy Crates. So long as you have a Ground Unit standing close by, you will automatically collect these three Crates.

In an online game of Blitz, the number of Pods you destroy and Crates you collect will be determined by your playstyle and the opposition. In a game of Blitz Firefight, the enemies will not pay attention to the Energy Pods; they are yours for the taking, provided you can manage destroying/collecting them while defending your zones simultaneously. On average, you will need to destroy 50 Energy Pods and collect its contents (3 Crates per Pod). Once you've managed just that, this achievement will unlock.
