Hellpoint

This is one of the final bosses of the game. Once you collect 100% data you return to the console by the Archon Slaver boss at the beginning of the game and will use an elevator to go to the High Ateliers. Reaching the end of the area you will meet the Interface and it will ask you to give the data to it, but if you refuse you will start a boss fight with it. Simply defeat it and you will get the achievement. Very easy boss as it seems broken, I just stuck close to one of it's arms attacking it when I could and it never was able to attack me. I wouldn't even be able to tell you what any of the attacks that it does are as I haven't seen it attack, only move around in a circle trying to get away from me.
