Halo Wars 2

This achievement will likely come naturally over the number of online matches you play as Colony, but it can be done quickly in solo Skirmish matches against the AI on Easy. If you're taking this route, head into the Skirmish lobby and make these setting changes:

• Gametype: Deathmatch
• Starting Supply: 9999
• Starting Power: 9999
• Fog of War: Off
• Skulls: After Party

Now choose Colony as your leader and begin the match. Once the match starts, quickly move around the map and build a base on every available plot. You can destroy each base as soon as they're in exchange for a tank (courtesy of the After Party Skull). Continue to build and recycle bases until you have a sizable or capped population of tanks. From here, you can send all your units to the AI's sole base and destroy it with relative ease.

After the base is destroyed, proceed to eliminate the enemy tank that spawns in its place and you will win the match. Repeat this method twice more if needed and the achievement will finally unlock.
