Standard geo sea

Baseline cove-side sea play: bot lab then shipyard in the cove around 3:06, first Syracusia by 5:04, geothermal on time around 7:42 and an Advanced Metal Extractor to build up eco, transitioning into more Syracusia and Argonaut over the…

HOW TO PLAY IT

Key timing: First Syracusia by 5:18

  1. Take 3 mex and open into wind while starting the bot lab.
  2. Rush the bot lab finish for early defense on the coast.
  3. Get the shipyard up to start frigate production.
  4. Push the first Syracusia frigate out for sea control.
  5. Layer geothermal and advanced mex, then keep feeding the Syracusia navy.

WHAT THE NUMBERS SAY

Standard geo sea sits near an even split on wins while destroying more metal than it loses by 15:00, typical for a contested sea role.

  • + Enemy metal destroyed reaches 7775 by 15:00 against 4863 lost.
  • + Syracusia dominates army composition at 43%, showing a clear naval focus.
  • − Team win rate is only 47%, essentially a coin flip.
  • − T2 factory only completes in 32% of games, so tech transition often stalls.
