1: Use Windows Explorer and go into the campaign file.
2: Go in either cybrid or human file.
3: Open the campaign file (if it asks how to open it
  scroll down and click on NOTEPAD) (on human side it
  should be the 1st file, on cybrid: 34th).
4: Where it says usePlanetInv = true; (In 29th row of
  cybrid side and 33rd on the human side,) erase true
  and replace by typing in bool. so the row should say:
  usePlanetInv = bool;
5: In the 36th row of the Cybrid side, 40th on human side,
  where it says techLevel = 3; and replace the three with 10.
  So it should say techLevel = 10;
6: Save your files and exit.
7: Start a new campaign using the side(s) that you changed.
