Nice work. I tried playing on that map, once. I managed to almost single-handedly get within a few blocks of the platform, then an enemy managed to dig his way underneath and destroy the four block wide base holding the whole bloody thing up. Needless to say, I ragequit.
There's a whole bunch of Babel maps; that one was the one with a bunch of craters pockmarking it and a single sunken lake with an island in the center.
We actually had our first tower almost totally collapsed after getting only 3 of 10 points, so we had to rebuild the whole thing. But the addition along the edge of the platform connected to the bird beak (which is also the staircase) means that they'd need to destroy literally the entire center of the bird to bring it down. So not only does it look ridiculous and epic, but it's exceptionally secure against assault and lets us win unimpeded.
I still think my best personal work was on nomansland, where I teamed up with a Brazilian guy who didn't seem to speak any English and dug a tunnel directly from our tent to the enemy intel, across the entire map. And the other guys never caught on.
