THE CATCH, AND WHAT COMES WITH IT
  • SheldonSheldon in 41%20% of all Geo games by then

Then transitions into Sheldon (22% of army), Sumo (8% 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.
