Hints & Tips

Beating Hennessey
You need to fight Hennessey three times before you can win. The first time he will have an electric riot shield, making it useless to attack him head-on. In order to beat him, you have to first get rid of the shield. To do this, lure Hennessey into the fountain in the center 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 be shocked also. Another way is to continually circle the fountain, keeping a distance between Hennessey and yourself. While circling, there should be a gun lying on the ground, close to the water. You can pick this gun up and shoot Hennessey with it, slowly taking out his shield. Do not worry about ammo, as the gun regenerates. This may take time, but it is possible to kill Hennessey without receiving damage. After the shield is broken, Hennessey runs off to hide, and mocks you. You will have to take out a couple of his GAC goons, but they provide no more of a fight than they did earlier. 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 prior to the fight. In order to beat Hennessey you now have to fight him hand to hand, except he has an edge, fire fists. Do not let him get too close to you, but at the same time, try to throw him as much as you can. In time when he gets to half health, he will comment about how it is getting chilly and open a furnace door. This is where it gets a little easier. Throw Hennessey into the new area and watch his health lower as he burns. Repeat this to take him out for the second time. The third time, he walks out totally engulfed in flames, at full health. Even though he is encompassed by flames, continue throwing him into the furnace so that he can receive more damage and you will avenge your father's death in time.

Training: Unlimited ammunition
At the start of the training, after you have blown the men up with the canister, switch weapons to your pistol. You can shoot with out running out of ammunition.

Destroying the clown van in the cemetery
Use the canisters that explode and drop one on either side of the gate, in the corner between the wall and the gate. Do not throw it. Walk away and shoot the canister. Repeat this until the van is destroyed. This may take some time but it works.

Throw a few canisters at the van without shooting them. This works best when at mid field. When you have them in front of the van, throw one at the van and wait until the can gets directly in front of the gunner then shoot it. This will take a lot of life out of him. A few more and it is done.

Beating people without guns
To beat people that do not have guns easier, keep on blocking and dodging. If you do not dodge, you will still be harmed. When you are in the prison, you will learn how to reverse a grab. This will allow you to avoid being hurt when they grab you. When you reverse the grab, you will throw their arms in the air. This will leave them open to attack (punch, kick, grab, etc.). However, they can still block.

Chapter 1: All pistol disarms
When you begin this level, a man will appear and attempt to shoot you. Lock on to him and use your dog (Shadow) to kill him. Shadow will bring his gun to you. When you kill him, another man by a crane will start to shoot. Then lock on to him and shoot him with the gun you obtained. When you kill him, some pipes will fall down, making it appear as if you cannot get through. However, you can. Right after you enter, a man will come up behind you and say "Drop it!". You will throw down your weapon and turn around. When you turn around, you will not be able to move anymore this will make it a bit easier. You will be asked to press Circle to disarm him. You can either do that, or do it with the Analog-stick. To obtain all of them, keep doing the level over or try it the old fashioned way.

Disarms
All types of weapon has five disarms (Circle, Up + Circle, Left + Circle, Right + Circle, and Down + Circle). One that doesn't is the shotgun, which is Circle and Up + Circle. Note: Turn off the "Random Disarms" option or you will not learn any new ones.

The disarms are held by one enemy on each level that possess guns. Proceed through the levels, disarming everyone that you can. Keep tabs of who you were able to disarm in a certain room before you die. When you go on, you will know which ones are left to disarm until you check everyone. Then, move on, save, and repeat. There is a shotgun disarm on mission 2 after the Boss. There are five disarms for every weapon, including the shotgun. The enemies will only unlock disarms for the weapons they use, and of course there are no disarms on the levels without guns. Always use cover, duck behind something, or wait around a corner and be patient. Eventually, they will draw closer to you. Then press one of the Circle combos and their fate is sealed. Draw them closer one by one and disarm them or take them hostage systematically, while never exposing yourself. The objective is to not to get shot, or go down in a blaze of glory.

These are all the disarm moves in the game.

Chapter 14: Fahook uses bottle
After you have beaten Fahook once he goes into the back of the plane, when you get him low on life he will drink from his bottle. At this time you should shoot the bottle out of his hands before he gains too much life. Doing this three or four times will demolish his bottle. Finish off his lingering life points and watch the intermission sequence. Also, use the manual aiming to shoot things. When you are on manual, you can aim at the bottle. You will need to do this three or four times. When the bottle is shot off Fahook, you need to make Fahook go near the open back part of the airplane. Once there, shoot him and Fahook will fall out and die.

Flaming Fisted Man warning
After you have beatenFlaming Fisted Man, the game restarts itself. This does not allow you to save your game, meaning that you either start a new game or keep on fighting Flaming Fist Man continually.

Beating the helicopter for the last time
The instant when the level starts, run up to the pillar in front of you for cover. Go into wall mode and equip Shadow as your weapon. Spin out to the left and kill the first man. Exit wall mode and wait until the second man is near you, then kill him. There will be more men. Stand back and kill them from close to the pillar. If one gets to close, it helps to use him as a shield. After men stop appearing from the helicopter, equip your M4 and target the man across the room on the raised section of the level. Do not target anyone on the highest balcony. Run at him while firing. Just be careful he has a rocket launcher. Run side to side. Also be careful not to run past the fountain. If you do, the helicopter will be able to shoot at you. After killing that man, make sure no one else is coming from the helicopter. Get the rocket launcher that is in front of the fountain. After that, equip your rocket launcher and run back to the point on the ramp where it starts to go down. This ramp is near the beginning and between the two pillars you started at. Manually aim at the helicopter from here. If you cannot hit it, move forward until you can. Do not miss with the rocket launcher, as it will take longer to beat the helicopter. Use every gun you have and all your ammunition on this. It does not do much, but it will work. After all your ammunition is used, go left and act as if you are going up the balcony stairs. Go up them to the first platform and retrieve the pistol. The last man you have to kill will be there. After you have killed him, run back to the ramp and shoot the helicopter with all your ammunition once again. The pistol will appear again in the same location. Get the pistol again. There will not be any more men. Go back to the ramp again. Shoot the helicopter with all your ammunition. Keep repeating this until the helicopter is destroyed.

Beating Pinnacle
While you are fighting Pinnacle, repeatedly press Jump to dodge his attacks easier. Jack will automatically turn to face Pinnacle before he jumps you do not have to worry about getting too far away from him. While Jack is jumping, he is resistant to all of Pinnacle's attacks. Do this continually to tire Pinnacle out, then jump on his back and finish him. You can also attack Pinnacle in front by punching and using low kicks, but this is not suggested as it does not take away much damage from Pinnacle.

Chapter 3: Spine break
When you are locked up "Iron Point" and are walking around in the hall only two or three people will be in the area. One of them will run up to you and say something. When you run away, they will start to walk away. As they walk away you can go in back of them and preform the grab. However, they move too much and you will end up breaking their back.

Chapter 3: Ledge in mine
If you are having difficulty getting across the ledge in the mine after the prison break, go to the wall with the ledge and enter "wall mode". You will scoot across and will not fall into a darkened abyss.

Chapter 13: Voice access
First kill one of the men that has green on. You will see a man in yellow walk out in the open and run back. After a moment, the man in the yellow will run over to you. When he does grab him. If another man runs with him, kill him and leave the man in yellow living. Take him to give the voice authorization and you will now be able to open gate. When you go over to the gate, a lot of men will be here. An easy way to kill all of them is to run up to them and grab one as a shield. The man you grab will get killed swiftly. Keep doing this until only one person is left.

Mini-games
To unlock the mini-games, successfully complete the game under any difficulty setting.

Beating Diggs
Diggs is the ex boxer you will have to face later in the game. When he get's three quarters of his health, gas which hurts you will be turned on. You can knock off his gas mask and put it on. Keep pressing Triangle to dive and he won't touch you. His power will slowly go down, and he will soon be killed.
