Has anyone unlocked this one yet? I've destroyed as many buildings as I can in a few different areas and it hasn't unlocked.
Which level is it supposed to be? The area before you fight Crimson Dynamo?
EDIT: Alright, got it now. It is the area with the objective "Access the facility subnet", there are a bunch of marked buildings, hit them all with your Uni beam which blows the roof completely off (I think this was my problem, I was using other weapons previously and there were always a couple of sheets of roofing left). I had destroyed a few of the smaller buildings before I started using the Uni beam on the marked buildings so I'm not sure if they count or not, but as soon as I hit the last marked building the achievement popped.
