This game is bad..... I mean really bad. But for those of you who want help getting the badge, here's some advice: 1. If those squids hang on to a building too long they capture it. It counts as lost. People tend to think that they die when they have buildings left, but these are captured building, and won't be destroyed. 2. I am very convinced whatever damage that you do to the mothership at the beginning of level 7 carries over to when you fight it again, so save a Spread power up for it. 3. Go into the each boss with as many Laser and Missle powerups as you can and use them quickly. 4. The more buildings you save throught the course of the level the longer you'll have on the bosses. Focus on the bombs; bullets from the brain and the squids don't do anything to your buildings. Hope that helps.
