HOW TO PLAY IT

Key timing: Aircraft Plant by 1:24

  1. Open 3 mex and wind, then drop Aircraft Plant early.
  2. Finish Aircraft Plant and start fighters for scouting and defense.
  3. Eat the Aircraft Plant once production needs outgrow it.
  4. Get Advanced Metal Extractor up to scale eco.
  5. Bring Fusion Reactor online and keep feeding transports, scouts, fighters to allies.

WHAT THE NUMBERS SAY

Standard air play wins less than half its games, with very low combat losses and kills since the role mostly supports rather than fights.

  • + Own metal lost stays very low, only 2701 by 15:00.
  • + Metal production reaches 25740 by 15:00, a strong support economy.
  • − Team wins under half of games (47%).
  • − Enemy metal destroyed stays low at 2097 by 15:00, showing little direct impact.
