I still don't think you quite understand. When you destroy the level 1 turret, it brings out the level 2. When you destroy the level 2 turret, it brings out the level 3.

Ah, so then level 3 comes out and you die no matter what. So you're basically doomed as soon as the level 1 turret descends (unless there's a way to leave the area).
If you just stop shooting once the level 1 turret appears, you'll be safe. It's just there to warn you that you are doing something wrong and should stop. Continuing to shoot is what makes the turret open fire. Level 2 is the point where you are actually doomed. I think.
