Then transitions into Sheldon (27% of army), Sumo (8% of army).

HOW TO PLAY IT

Key timing: T2 bot lab by 8:03

  1. Open 3 mex into early Bot Lab and solar.
  2. Bring geothermal online fast to fund the tech rush.
  3. Finish Advanced Bot Lab to unlock T2 bot units.
  4. Push Sheldon (and Arbiter, Sumo) to front as the first T2 units.
  5. Switch into T2 construction bots to supply allies with T2 cons.
