After the battle with Bullseye Frank's blind lawyer Matt Murdock (Daredevil's alter ego) comes in and Frank fires him.

When in KingPin's office, throw grenades at him. Do not try to shoot him unless you aim for the head; bullets do not hurt him. Just keep throwing grenades until he dies.

To defeat Bushwacker you must do two things. First, aim for his head and fire. Eventually, his glasses will fall off. Once, his glasses are off it is a free for all as long as you have some flashbangs. If you do not have flashbangs, then just kill
some henchmen and they will drop some. Begin launching flashbangs near Bushwacker and he will get disoriented. When he starts moving around like he is drunk, start shooting him. He will begin to fire his weapon, but most of the time he is inaccurate. He eventually will die after enough damage is taken.

Jigsaw is quite possibly the easiest fight in the game (if played smart). First, take out Jigsaw's jet pack. Simply walk over to a cargo crate. Make sure that you can see Jigsaw, but he cannot see or hit you. If you wait, Jigsaw will come to you. When he gets close enough, run under him. Then, just shoot his backpack and stay under Jigsaw. After a little cat and mouse, an intermission sequence will play. Jigsaw is now on foot. Jigsaw's way of defense are ten fast blasts and a large plasma ball. You will need to run in between boxes to throw him off your path. Run around until you see a guard, then finish him quick. The guard will drop a RAM explosive. These are used by walking up to a wall and pressing Secondary Fire once (while RAM is selected). The charge is now armed and ready for detonation. Get Jigsaw's attention by letting him see you. He will run after you. When he gets near the RAM, press your Secondary Fire again (maintain safe distance) and an explosion will blow off a piece of Jigsaw's armor. Repeat this procedure until Jigsaw falls to your punishment.

When you reach this part of the level, you may be compelled to take the sniper rifle to your left. You can if desired, but it is not required. If you want to get out quick, run to the middle rock near the edge (where the chopper is flying). You will find an anti-tank launcher (rocket launcher) and what may be an unlimited ammo cache. Try to aim for the man with the rocket launcher in the chopper (usually on the right). After you hit him, keep firing missiles at the chopper. Make sure that you strafe (or at least keep moving), as there are snipers in almost all directions around you.
