HOW TO PLAY IT

Key timing: Shipyard by 2:06

  1. Take mex and wind while queuing the shipyard early.
  2. Get the shipyard up before 3:24 to start naval production.
  3. Add Argonaut and Iapetus to back up the early push.
  4. Push out a Syracusia fast to contest or scout enemy sea.
  5. Transition to T2 with an advanced mex as navy expands.
