Apocalyptic Missile Commander Badge (hard – 30 points)
Complete the "apocalypse" difficulty setting



The medium badge is really easy, seriously. I got it in my first try on easy mode, without knowing how to play. If it’s hard for you, you can get both badges at the same time using the walkthrough for the hard one.
So yes, for the hard badge, Yeknomssa posted in the forums an awesome walkthrough in 13 detailed and easy-to-follow steps. The game is long, so even with this walkthrough, it takes 30-45 minutes to beat it. Follow the steps carefully if you want to win (you are free to modify the walkthrough, though). If you are leaving, make sure you pause the game! It’s not good to lose on the 10th step. Yes, it happened to me.

Once again, thanks to Yeknomssa.
