Geo / Cortex / Economy first / OBSERVED BUILD

Standard geo

The role's normal economy-first plan: geothermal into T2 constructor and advanced bot lab, then Sheldon-led T2 bots sent to front as the team's early T2 supply.

Usually blows up the commander for T2 (69%)

THE CATCH, AND WHAT COMES WITH IT
  • SheldonSheldon in 43%20% of all Geo games by then

Then transitions into Sheldon (22% of army), Sumo (9% of army).

HOW TO PLAY IT

Key timing: T2 constructor by 5:01

  1. Take 3 mex, then chain wind and a bot lab by 1:13.
  2. Get geothermal up for the energy to push tech.
  3. Hit T2 constructor and start advanced mex and advanced geo.
  4. Bring up the T2 lab and start pumping Sheldon to front.
  5. Pay allies with cons and rez bots while supplying Sheldon and Arbiter.

WHAT THE NUMBERS SAY

Standard geo won under half its games while destroying far more metal than it lost by 15:00, showing the T2 push pays off when it lands.

  • + Enemy metal destroyed hits 7969 by 15:00 versus only 6290 lost.
  • + Advanced geothermal reached in 67% of games, funding a fast T2 lab.
  • − Team win rate sits at only 45%, below an even split.
  • − First Sheldon only appears by 9:06 in 31% of games, so T2 units often arrive late.
