Aliens Must Die : The Jupiter Wars

and there i was thinking it was enjoyable and easy, every enemy was easy, then i get killed by a bunch of rocks, unbelievable haha

To anyone complaining about enemies spawning on top of them: just watch out for the barely-visible spawning animation with the faint circles moving inward (for your convenience, these are coloured almost identically to the many explosions and the visual effects of your shots striking not-yet-dead enemies). Don't forget to simultaneously watch out for attackers zooming in from the edge of the screen. Unless you have a visual system designed for focusing on a specific area instead of processing all incoming data at once, you should be fine.
Oh, wait, this is meant to be played by biological organisms such as humans? Never mind.

So, basically, while all these strategies are good, they won't do much without the health pickups. The health pickups are the #1 most important thing in getting the hard badge. You do only want to upgrade your weapon to 4 or 5. After that you're just taking unneeded risk in taking damage. The shields are also very helpful. They don't work like most games. When you hit an enemy, it kills them instantly, and you keep it until it fades away. So once you get it, just ram into everything until it goes away.Other than that, damage avoidance is the main concern. Lastly, once you reach 29, your basically home free. The mother ships don't have a ton of health and it's easy to avoid their fire by just circling around them.

When you have shield at level 29 just bump the mothership and you win *-*

Nah it's cool, just spawn right on top of me. Don't mind that sort of stuff at all.
