Tzar rush

Cortex Geo build order · Supreme Isthmus

Geo rushes its own vehicle plant and advanced vehicle plant to field a Tzar (or early Tiger) around 6:40, far earlier than the role's typical first-Sheldon timing, pushing it to the middle with T2 vehicle artillery and support.

THE CATCH, AND WHAT COMES WITH IT
  • TzarT2 vehicle assault from 6:41 · 3% of role by thenFrom the Advanced Vehicle Plant. Only 3% of Geo games have it by then; others who build it get it around 10:12
  • Advanced Vehicle PlantAdvanced Vehicle Plant in 100%11% of all Geo games by then
  • ObscurerJammer in 70%8% of all Geo games by then
  • Vehicle PlantVehicle Plant in 67%14% of all Geo games by then
  • QuakerQuaker in 58%11% of all Geo games by then

Started with Tzar (61%), Tiger (39%).

Where those units first fight, in 32 games with kill data: in the middle 88%, on their own side 13%.

Those units destroy a typical 4,603 metal of enemy units by 15:00.

Then transitions into tiger (34% of army).

HOW TO PLAY IT

Key timing: Advanced Vehicle Plant by 4:59

  1. Open mex and wind, skip the usual Bot Lab focus.
  2. Drop Vehicle Plant, then push straight into Advanced Vehicle Plant.
  3. Send first Tzar (or Tiger) to middle well ahead of role norm.
  4. Bring jammer support and Fury anti-air alongside it.
  5. Reclaim Advanced Vehicle Plant and keep making T2 vehicles for front.
