Standard geo sea

Legion Geo sea build order · Supreme Isthmus

The role's baseline: bot lab reclaimed for metal, shipyard built in the cove, Syracusia and Geothermal Powerplant on normal timing, transitioning into Argonaut and other naval units to contest the sea for the rest of the game.

Usually shipyard in the cove (94%) · geo on time (61%)

HOW TO PLAY IT

Key timing: Shipyard by 3:06

  1. Open with mex and solar, then put down Legion Bot Lab for reclaim.
  2. Build Legion Bot Lab early, planning to eat it for metal.
  3. Build shipyard and reclaim the bot lab into the sea economy.
  4. Eat the Legion Bot Lab at 3:12 to fund early sea units.
  5. Add Syracusia then geothermal, transition into Argonaut-led sea army.
