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".
