Diggs is the ex boxer you will have to face in the later part of the game. When he reaches three quarters of his health, gas which will hurt you will be turned on. You can knock off his gas mask and put it on. Keep pressing Triangle to dive and he cannot touch you. His power will slowly go down, and he will soon be defeated.
Training: Unlimited ammunition:
At the beginning of the training, after you blow 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 the process until the van is destroyed. This may take a while, but it works.
Flaming Fisted Man warning:
After defeating Flaming Fisted Man, the game restarts itself. This does not allow you to save your game, meaning that you either start a new game or continue fighting Flaming Fist Man repeatedly.
Defeating people without guns:
To defeat people that do not have guns easier, keep blocking and dodging. If you do not dodge, you will still get hurt. When you are in the prison, you will learn how to reverse a grab. This allows you to avoid getting 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.
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.
While fighting Pinnacle, repeatedly press "Jump" to easily dodge his attacks. 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 impervious to all of Pinnacle's attacks. Do this repeatedly to tire Pinnacle out, then jump on his back and finish him off. You can also attack Pinnacle in front by punching and using low kicks, but this is not recommended as it does not take much damage from Pinnacle.
Destroying the clown man in the cemetary:
Use the 7 canisters that explode and drop 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 the process until the van is destroyed. This may take a while, but it works.
