This achievement is for beating a very intense boss fight. This fight will be the next mission after escorting the Bloodtox pumping device to Times Square.

During the boss fight, the boss will be held aloft by an overgrown spinal column and 3 masses of flesh. These masses of flesh must be attacked but the boss has several attacks that work very well in deterring you from getting up close. The boss also has several very damaging long ranged attacks. This means that while on foot it is very much in your interest to keep moving as much as possible.

When the battle first starts, it will just be you versus the boss and several smaller infected that keep respawning. Activate your armor ability and leave it on for the remainder of the battle. The most effective way I found to attack the supporting masses of flesh is to activate the whipfist and spam the Y attack to attack from as far away as possible. It's best to try attacking while jumping as this will make it easier to avoid attacks from both the boss and the smaller enemies. If your health gets too low, hide around the corner of a building from the boss and consume some enemies for health.

When all 3 flesh masses are destroyed, the boss will fall to the ground. Pull out your blade power and run up to her and hack away until you take 1/4 her energy. She'll then retreat underground.

After a short while, you'll see a cutscene of the military showing up and the boss re-emerging. You must now repeat destroying the 3 flesh masses then damaging the boss 3 more times. That said, the military being involved makes this much easier from here to the end of the fight. Their tanks will keep some of the enemies distracted. Plus, being inside one of these tanks increases your firepower and survivability. Therefore, it is in your best interests to be in a tank as much as possible for the rest of the battle.
