  • SumoSumo in 40%16% of all Geo games by then

Then transitions into Sheldon (25% of army), Sumo (9% of army).

HOW TO PLAY IT

Key timing: T2 bot lab by 8:03

  1. Open 3 mex into early Bot Lab and solar.
  2. Bring geothermal online fast to fund the tech rush.
  3. Finish Advanced Bot Lab to unlock T2 bot units.
  4. Push Sheldon (and Arbiter, Sumo) to front as the first T2 units.
  5. Switch into T2 construction bots to supply allies with T2 cons.

WHAT THE NUMBERS SAY

Standard geo play wins less than half its games but builds a big eco lead, reaching nearly 31.5k metal production by 15:00.

  • + Metal production hits 16919 by 10:00, well ahead of most roles.
  • + Own metal lost stays near zero (260) by 10:00, a very safe tech rush.
  • − Team wins under half of games (46%).
  • − Enemy metal destroyed stays low (423) by 10:00, showing slow early impact.
