Cortex Geo sea build order · Supreme Isthmus

Builds Bot Lab then Shipyard in the cove, eating the lab for metal, and pushes out Orca, Riptide and Oppressor to contest the sea starting around 4-6 minutes, transitioning into a Riptide/Oppressor-heavy navy over the rest of the game.

WHAT THE NUMBERS SAY

This is the role's own baseline, winning a bit over half its games with steady eco scaling and sea trades roughly matching losses.

  • + Team wins slightly over half of games played.
  • + Metal production scales from ~4k to ~29.5k by 15:00.
  • − Own metal lost climbs to 6875 by 15:00, matching kills closely.
  • − T2 factory only reached in 40% of games, limiting late power.
