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".
