Trophy "Breakfest"

[wvwwvvv]

Hey,
does anyone know how this trophy works? The Breaker is supposed to have armor all over its body,

but no matter how much I shoot the Breaker, it dies before all its armor is broken.

This has already been clarified. You can now find something about it on the Internet (which was not the case all the time).

You have to play nightmare and destroy the "armor plates" of the weak points on the body in Act 1 "Clean Sweep" of the Breaker.

I guess the breakers that can spawn randomly will have these armor plates on nightmare too, but I don't know that (yet).
