HOW TO PLAY IT

Key timing: Bot Lab by 0:40

  1. Open 2 mex into early Bot Lab.
  2. Finish Bot Lab and start Thug, Grunt, Aggravator mix.
  3. Send first units to coast to stop leaks, not straight to mid.
  4. Transition into Advanced Metal Extractor as eco scales.
  5. Move units up as a line toward middle to hold the wider gap.
