This achievement is for beating the final boss of the game. This is not going to be an easy fight.

This boss has some really devastating attacks, including a ramped up version of your tendril devastator. If you get caught in that attack, you might as well pause and quit to the main menu because you will die pretty much no matter what your health was when you get caught or whether or not you have the armor skill active. Because of this, you'll really want to try to keep your distance, but you also must keep moving because the boss is very fast himself.

During the first 2/3 of the bosses health bar, the military will be involved in the fight. You could just let them whittle away at him as you run away if you want to, but this will take a very long time and once you hit that final 1/3 of health will no longer be an option. When the bosses health reaches that point, the military will abandon the ship and a 1:45 timer will kick in. At this point you must defeat the boss quickly.

The easiest method I have found for defeating the boss is to use a power you likely haven't used at all up to this point, the Musclemass Power. Turn it on then just run around tossing things at the boss. Depending on the item thrown, you also have a chance to stun him allowing you to deal a lot of damage. Also, if you get a large opening, like the boss using his devastator and their are several enemies around, try consuming them and trying to reach critical mass. If you manage it, use the Critical Pain Devastator (X+B), preferably in the air to help avoid attacks, to cause massive damage on him.
