Whirlwind rush

Cortex Geo build order · Supreme Isthmus

Geo adds an Aircraft Plant around 6:50 and pushes T1 bombers led by Whirlwind, with Valiant fighters and Finch scouts following, landing hits deep in the enemy base from as early as 8:52 well before the usual T2 push.

Usually blows up the commander for T2 (70%)

THE CATCH, AND WHAT COMES WITH IT
  • WhirlwindT1 air bombers from 7:00 · 9% of role by thenFrom the Aircraft Plant. Only 9% of Geo games have it by then; others who build it get it around 7:29
  • Aircraft PlantAircraft Plant in 98%18% of all Geo games by then
  • ValiantValiant in 74%11% of all Geo games by then
  • FinchFinch in 52%7% of all Geo games by then
  • ValiantValiant in 48%6% of all Geo games by then

Started with Whirlwind (98%), Stormbringer (2%).

Where those units first fight, in 46 games with kill data: in the middle 52%, in the enemy base 46%.

Those units destroy a typical 1,980 metal of enemy units by 15:00.

Then transitions into Sheldon (14% of army), valiant (9% of army).

HOW TO PLAY IT

Key timing: Aircraft Plant by 6:57

  1. Open bot lab as usual but plan to eat it by 3:27.
  2. Get geo up on schedule to fund the air switch.
  3. Build Aircraft Plant instead of the usual T2 bot path.
  4. Push Whirlwind bombers straight into the enemy base.
  5. Reclaim the Aircraft Plant and transition back to Sheldon and T2 units.
