Geo sea / Cortex / Economy first / OBSERVED BUILD

Standard geo sea

The role's default economy-first play: bot lab then shipyard in the cove, quick frigate/submarine/destroyer navy to contest sea and hold the coast, transitioning into whatever the sea fight needs.

Usually shipyard in the cove (98%)

HOW TO PLAY IT

Key timing: Shipyard by 3:18

  1. Open 3 mex, wind and solar, then Bot Lab.
  2. Get a BP and costal torpedo launcher up before the Shipyard.
  3. Put up Shipyard once you can defend it.
  4. Push out "submarine" and "frigate" to contest the sea.
  5. Add geothermal to fund the fleet transition into "destroyer", "missile corvette".

WHAT THE NUMBERS SAY

Standard Cortex geo sea sits at an even 50% win rate, trading a slower start for a big resource lead by 15:00.

  • + Metal produced hits 28451 by 15:00, well above both front roles
  • + Own metal lost stays far below enemy metal destroyed at every checkpoint
  • − Only 50% team win rate, the lowest of these six builds
  • − T2 factory only completes in 40% of games by 12:53
