Beach sea / Legion / Economy first / OBSERVED BUILD

Standard beach sea

Builds a shipyard early, gets a Syracusia out fast to contest or scout enemy sea entry, then expands into an Advanced Metal Extractor and more navy over the first 15 minutes.

Usually shipyard first (76%)

HOW TO PLAY IT

Key timing: First Syracusia by 4:42

  1. Take 3 mex, then send the commander to build the shipyard.
  2. Get the shipyard up fast to start early sea presence.
  3. Add tidal generators for the energy to sustain frigate output.
  4. Push the first Syracusia out to contest or scout the sea.
  5. Bring advanced mex online to catch up economy for the late game.

WHAT THE NUMBERS SAY

Standard beach sea has by far the lowest team win rate of the six builds despite comparable early frigate timing, suggesting the natural resource disadvantage described for this role bites hard.

  • + First Syracusia at 4:42, faster than geo sea's 5:18 equivalent.
  • + Metal produced by 5:00 reaches 3704, close to other sea roles.
  • − Team win rate is only 21%, far below every other standard build shown.
  • − T2 factory completes in just 21% of games, the lowest tech follow-through listed.
