way too easy. all you have to do is use the troops and fire support until you research everything, then at the biggining of all the other lvls, spawn 5 gun men, for the capturing of turrets and oil rigs, spawn a navy ship, for killing tanks and ground units, spawn 3 helicopters and then 1 jet fighter. after that, you can use the laz0r cannon to eliminate enemy air unites and navy units, and then the bomb for all the ground units.
On the mega boss just right click after it goes up, click "Loop," then right click again and hit "Loop," again, and the button comes back down. Click it.
