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.

Usually shipyard in the cove (98%)

HOW TO PLAY IT

Key timing: Bot Lab by 1:12, Shipyard by 3:17

  1. Open 3 mex into wind, then drop Bot Lab in cove.
  2. Finish Bot Lab, keep teching mex and wind.
  3. Get Shipyard up and start pumping subs and frigates.
  4. Eat the Bot Lab for metal once you have T1 units defending.
  5. Push out submarine, frigate, destroyer to contest sea.
  6. Bring geothermal online and transition toward T2 constructor.

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.
