HOW TO PLAY IT

Key timing: Shipyard by 1:57

  1. Open 3 mex and wind while com heads straight to sea.
  2. Drop Shipyard fast, before 2:00, to seize early sea presence.
  3. Push "frigate" out to contest enemy sea entry or hold vision.
  4. Add "destroyer" as the fleet grows.
  5. Transition into Advanced Metal Extractor to catch up on eco.
