HOW TO PLAY IT

Key timing: Bot Lab by 0:40

  1. Take 3 mex, then wind before opening Bot Lab.
  2. Finish Bot Lab, start producing Thug, Grunt and Aggravator.
  3. Send early units to coast first to stop leaks, not straight to mid.
  4. Add Twin Guard and Radar Tower to hold the wider gap.
  5. Bring Advanced Metal Extractor online as army transitions to T2.
