Defeating Hennessey

You have to fight Hennessey three times before you can win. The first time he will have an electric riot shield, making it impossible to attack him head-on. In order to defeat him, you have to first get rid of the shield. To do this, lure Hennessey into the fountain in the middle of the battle area. He will electrocute the water and shock himself. Make sure that you are not too near the fountain or you will get shocked as well. Another way is to repeatedly circle the fountain, keeping good distance between Hennessey and yourself. While circling, there should be a gun lying on the ground, relatively close to the water. You can pick this gun up and shoot Hennessey with it, slowly taking out his shield. Do not worry about ammunition, as the gun regenerates. This may take awhile, but it is possible to kill Hennessey without taking damage. After the shield is broken, Hennessey runs off to hide, all the while mocking you. You will have to take out a couple of his GAC goons, but they provide no more of a fight than they did in previously. Note: You are now weaponless. Do not get too excited when you find the gun sitting in front of the doors -- it gets knocked out of your hands and out of reach before the fight starts. In order to defeat Hennessey you now have to fight him hand to hand, except he has an advantage, fire fists. Do not let him get too close to you, but at the same time, try to throw him as much as possible. Eventually when he gets to about half health, he will comment about how it is getting chilly and open a huge furnace door. This is where it gets a little easier. Throw Hennessey into the new area and watch his health deplete as he burns. Repeat this to take him out for the second time. The third time, he walks out completely engulfed in flames, at full health. Even though he is encompassed by flames, continue throwing him into the furnace so that he can take more damage and you will finally avenge your father's death.
