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%)
