To unlock the Overachiever achievement, follow this simple endgame strategy.


Make sure you've reached the endgame phase, where you've already:

1) Purchased all available upgrades for the Oil Field.
2) Maxed out the Logistics Hub upgrades.

Place an Oil Field on Swamp terrain. This terrain gives a strong productivity boost and is key for maximizing your output.



Place Logistics Hubs in all 8 surrounding tiles around the Oil Field (in a 3x3 layout).
This will massively increase both Speed and Productivity, as seen in the screenshots.

Apply the Glitched Warped Speed skill directly on the Oil Field.
This boosts the extraction rate to extreme levels, helping you achieve the needed production spike.

Before this setup, it’s highly recommended that you use the City Builder skill a few times.
Doing so increases the number of cities on the map, which gives you an additional Speed Productivity from each city on the map.
