Defeating Luther in Coney Island - When you have Luther on the beach the second time (after defeating him the first time), do not worry about hiding behind this fence or the crate. Wait behind the boat, let Luther shoot five or six shots, then sprint directly up the middle until you are in front of Luther and throw a bottle. It will hit him in the face. Do not bother to aim or do anything else, just throw it.

Increasing stamina - There is an area once you get inside of the Warriors hideout where you can work out. You will be able to do chin ups, sit ups, push ups, and a heavy bag. At the end of each chapter you will be able to workout to increase your stamina. However, you will not be able to start working out until after Chapter 3. There are ten ranks for each exercise. They are as follows, with "R" being rank, and "/" being within seconds:

Chin Ups: R1=5, R2=5/11 sec., R3=10/21 sec., R4=10/19 sec., R5=10/17 sec., R6=15/32 sec., R7=15/29 sec., R8=15/26 sec., R9=20/40 sec., R10=20/35 sec.

Infinite money - After any mission in Free Roam mode, go to a jewelry store and break in. When inside, take the register and exit. Make a right and go straight until your base is on the right side. Go up the first set of stairs and stop. Turn towards the stairs leading farther up. Throw the register against the stairs in this position until it breaks. When it breaks open, stand over to collect the money. If done correctly, the register should keep giving you money until it reaches $999. Note: The money you collect may not be there during missions.

Free items - Go to a Flash dealer, and buy some Flash. Then, start to beat up the Flash dealer. When he fights back, hold Black and issue the command "Wreck 'em all! ". When you and your team have killed the Flash dealer, he will drop the cash that you gave him, and sometimes some extra Flash.

To get free items, just beat up the dealer. They will drop at least one item that they are selling. For free Flash, pay $40 for two Flash, then beat him up to get the third Flash for free, plus the money you just gave him. Once you can carry four Flashes, use the same technique, but pay for three to get the fourth for free. For free paint, you can only carry nine paint cans. Buy eight and get the ninth for free by using the beat-down method; you will also get your $40 back. For free knives, when you are able to pay for knives from a dealer, it is best that you do not spend more than $150. Each knife is worth $50. Pay for three and get the fourth for free. Note: The beat down method does not work when you need information from the bums sitting on the ground. Do not give them any more than $2. To get it back from them, do not beat them down; instead, mug them for it.

Flashback E - During Flashback E, your mission is to retrieve a size 9 hat. Playing as Cochise you will get the hat from the leader of The Boppers. When fighting Big Moe he will eventually drop his hat. When you put on his hat you must follow the button sequence correctly to get a free Flash. When doing the button sequence correctly, Cochise will begin dancing. You will need the extra Flash when fighting Big Moe. You will have two chances to get two extra Flash. Also, beat up the two girls that get involved to bring up your rage meter. This will help when you are fighting Big Moe.
