How to unlock the Persistent achievement in Super Destronaut DX - Definitive Guide
Occasionally after you defeat an enemy they will turn grey and fall to the bottom of the screen. When you shoot it, you receive 50 points each hit. It’s likely that you will earn this trophy without trying. If not, you need to do this for some of the challenges anyway. Be warned, these grey enemies will damage you if they hit you.
In random waves you'll sometimes get grey enemies that fall from the top of the screen down. Shooting them gives you points but they can't be killed. Shooting one once unlocks this achievement. You'll almost unavoidably do this inadvertently during Classic Mode, and Challenge Mode even has a couple challenges that require you to shoot grey enemies a set number of times, so this achievement will come naturally during other modes.
