Can you help me find an old alien shot'em up flash game?

I'm looking for an 6-8 years old alien flash shooter.
What I remember: The aliens had green masks with a grill in the front.
It was a bit gory. It was the sequel of an earlier game. Very voilent sounds of the aliens. Was originally posted on miniclip.com.

And I think you had to left click on the flash window and select play since the developer had screwed up the loading of the game.

Can anyone help me?
