Hints

Infinite Firestorm Wall
     If  you  have  a  firestorm wall and it is fully charged, you can
make  it  last  forever without having to turn it off to charge. First
charge  your  wall fully, then turn it on. Before it turns off or runs
out  of  power sell or turn off your power plants until t he words "On
Hold" appear in the firestorm Icon. Your wall will stay on forever and
will  not  run  out  of  power  until  you build or turn on your power
plants.

Level 9 Hint
     At  this  moment the most asked question is: "How do I get behind
the  lasercannon  ( The Obelisk of light )". Well, at the right of the
cannon  there  is a small base with a 'hand of NOD' building and a few
powerplants.  First  of  all  you must destroy the units on that base.
After that, destroy all the powerplants so that the NOD has low power.
Then  you  can pass the lasercannon or you can destroy it. When you go
to  the top of the map there is a base you can capture. Capture it and
destroy all NOD units.

Easy Way To Capture Construction Yard
     To  capture  the  enemy  construction yard while you are the Nod,
Build  a subterranean APC and put some engineers into it. Then tell it
to  go  to  the  enemies  base and unload the engineers to capture the
base.

NOTE: THIS WILL NOT WORK IF ENEMY HAS BASE PAVED OFF.

Infinite Troops
     During  the second mission build exactly 68 infantry to allow you
infinite troops on the 12th mission (make sure the troops don't die or
get injured or the cheat is invalid).
