Whirlwind bomber rush

Cortex Air build order · Supreme Isthmus

After the usual economy start, the player commits early (by 5:07) to T1 Whirlwind bombers that push forward and fight in the enemy base well before the role's norm, a clear forward plan rather than a reaction.

Usually transports first (66%)

THE CATCH, AND WHAT COMES WITH IT
  • WhirlwindT1 air bombers from 5:07 · 6% of role by thenFrom the Aircraft Plant. Only 6% of Air games have it by then; others who build it get it around 11:03
  • WhirlwindWhirlwind in 41%3% of all Air games by then

Where those units first fight, in 72 games with kill data: in the middle 50%, in the enemy base 49%.

Those units destroy a typical 1,057 metal of enemy units by 15:00.

Then transitions into valiant (48% of army).

HOW TO PLAY IT

Key timing: Aircraft Plant by 1:28

  1. Build Aircraft Plant immediately instead of the usual later timing.
  2. Commit to Whirlwind bombers well before the role norm of 10:48.
  3. Send Whirlwinds forward to fight in middle and enemy base.
  4. Reclaim the Aircraft Plant once the rush has paid off.
  5. Build Fusion Reactor to transition back into team support.
