I see the strategy for this is posted right below yours.. maybe you should read that. I just unlocked Invincible by just playing the levels on the same campaign save. Just change the difficulty to Formidable. With max upgrades and using War Machine with 2 mini guns as primary and 2 missile launchers as a backup you should run through the game without issue. Maybe you should try that.. only took 2-3 hours to finish the game.
