HOW TO PLAY IT

Key timing: Aircraft Plant by 1:23

  1. Take 3 mex and open straight into Aircraft Plant.
  2. Finish Aircraft Plant, start pumping Valiant for escort duty.
  3. Get T2 constructor going to scale eco alongside air production.
  4. Add Advanced Metal Extractor to keep pace with team's economy.
  5. Bring Fusion Reactor online, keep making Hercules and Finch for allies.

WHAT THE NUMBERS SAY

This is the role's standard support job, winning less than half its games while producing little combat impact but reliably feeding transports and scouts to teammates.

  • + Reaches Aircraft Plant almost immediately (1:23), fast T2 constructor by 5:58.
  • + Keeps own losses low (2789 by 15:00) versus other roles.
  • − Destroys only 2027 enemy metal by 15:00, minimal combat contribution.
  • − Fusion Reactor only completes in 57% of games, some games stall on eco.
