My brother just tried to make a gosling launcher with shots that get bigger when they split. Instead, he got shots that turn invisible, and later reappear!
Also, if you give a booster negative effect, cool things happen. You can have weapons turn on or increase their rate when other sections are destroyed. Here's one that lets a weapon fire only once until it is destroyed:
Here is a ship with these features: Linky
When the first aegises are destroyed, the weapons on the section it was protecting turn on. You could make cool bosses using this kind of effect. You know, where when you blow off its arm, it starts firing missiles at you? I hope to see some cool designs using this soon!
