Halo Wars 2

Unlike "Spare change," this achievement will take a considerable amount of time to unlock given its requirements. In truth, this is going to come naturally the more and more you play Multiplayer and Skirmish matches. That being said, if you do want to grind this out, you should set up a Skirmish match against the AI on Easy, making sure to make the following setting changes:

• Gametype: Deathmatch
• Starting Supply: 9999
• Starting Power: 9999
• Fog of War: OFF

Start the match and begin building Supply Pads and Generators (or Harvesters and Extractors if playing as the Banished) on every available plot of land around the map. Once they have been constructed, you can then upgrade them and begin building turrets, too. Eventually, you will have a steady stream of Power coming in, which means you can constantly upgrade your turrets over and over again by switching between the Anti-Infantry, Anti-Air, and Anti-Vehicle variants. Each time you upgrade a turret, you will gain credit towards a Leader Point that can then be used.

Continue this turret-upgrading process until you either have no more Leader Powers to unlock/upgrade or the enemy AI destroys your HQ and wins. Again, it's not necessary to boost this achievement, but it can help speed things up if you're impatient and don't want to play online too much.

After spending 100 Leader Points, this achievement will finally unlock.
