After Operations Intelligence getting to the Trump Building was absolutely easy.
Except for the invisible Aliens, I killed one there was an 80% chance another was near there that would enrage causing a patrol to merge into a firefight.
They didn't climb buildings, though. 2nd, 3rd Level, I could have whatever like donuts and milk.

The few Streets remaining to the Trump Building echoed English American Sexual urges- apprently anything played was sexuality, and it changed infrequently. The lighting was flashing as strobes, regardless that it was Daylight, and vapor was blown into the streets everywhere, the wind galed it out near the 6th-9th Levels. There was nothing in sight of a way of entry. 
I began to cross a Bridge there.
Killing invisibles was to be simply a fun start figuring it out.
The covenant were dead all over the Bridge when I got to my new killzone. The elites were sword dancing I saw. It must of slew all these former aliens. One'd get close to their raving quest to lie liking the music, I'd punch it's face, it'd not be dancing but flurrying-
