Fighting strategy
While fighting hand-to-hand or unarmed against multiple opponents, try not to get surrounded. Even though you can block attacks by holding R2, you can still get hit from behind. Try to single out opponents and focus on one at a time. Hold R2 to block anytime your not on the offense and strike immediately after an opponent attacks (and you block). Block any moves thrown at you, then quickly release R2 and tap X(3) to stun the opponent with three quick strikes. Then, immediately follow up with three heavy strikes (Square) to knock them to the ground. This gives you time to run over and kick them while they are down, or focus your attention on other opponents. Make sure you learn the Dojo move for the ground attack so you can knock away opponents around you and get up quickly if you find yourself kissing the pavement. If you are fighting opponents that are slower than you or are constantly using heavy attacks, hold R2 and tap Circle as they attack to do a counter-grapple move. If are grabbed by an opponent or knocked to the ground and they are on top of you, move the Left Analog-stick back and forth to break free or do a counter-attack. If your opponents are armed for melee in any way (with debris, pieces of the environment, or with any hand-to-hand weapon), immediately back off and look for a weapon. Chances are you will find one laying around if your opponents have one. It is important you match your opponent, otherwise you cannot block their attacks. If possible, out-do them weapon-wise. If they have a club, grab a blade. If they have a blade, grab a blade and a club. Do not forget you can fight with more than one melee weapon.
Fighting styles
If you are having trouble fighting thugs hand-to-hand in missions, it is best to drive around to different Dojos when not on a mission to learn different fighting styles. Some styles are better used on some opponents than others. The best styles are Thai Boxing and Tae Kwon Do. They seem to be effective on a wider variety of opponents and can defeat more fighting styles than other ones. Also, do not overlook your default "Brawling" fighting moves as they can prove very effective against some of the fancier martial arts like Wushu. Switch between styles while in combat to find the best one for each situation. If you can score hits with combos of three or more moves on one opponent without them blocking any of your hits (or stunning them), then your style is better than theirs. Also, during the "fight club" mini-missions you can sometimes get a hint as to what styles your opponents are going to use by the little gestures and moves they make before the beginning of a match.
Fire any weapon in vehicle
Most of the time you are only able to fire your .32 auto (the small default pistol) while in a vehicle and cannot use other weapons you have while driving. To use any weapon of your choice in any vehicle, tap L2 to enter or commandeer a vehicle as usual, but then press Down to switch from hand-to-hand combat to firearms and quickly press Left or Right to select any weapon you have in your inventory before Marcus gets into the car. You will now be able to use the weapon of your choice while driving around. This is especially useful if you have a high-powered or automatic weapon with you while chasing down suspects fleeing in vehicles.
Get cops to stop shooting you
Sometimes, when you are in your street clothes and shoot at someone in front of a cop, the cop will start shooting at you. To get them to stop, simply turn towards them and press Select to flash your badge at them. They should then stop shooting at you.
Non-fatal shots
When arresting people without killing them, go into aim mode by pressing R3. Put your sight over either their arm or leg, wait for it to turn blue, then shoot. They will fall to the ground, and you can then arrest them. This is useful for increasing your Good Cop rank.

Taking out key suspects easier
To disarm key suspects easier without killing them, raise your Detective level by solving street crimes to unlock the Taser pistol and Tranquilizer rifle (found in police station's basement armory). These weapons work well for safely capturing key suspects without killing them accidentally, and is much easier than trying to get an aim on their arms or legs for a "neutralizing shot".

When you go into the subway, walk from the stairs down to the other end of the platform. There is a wall, and on the wall is a subway map. If you look close at the map you can see that this is not the NYC subway map; it is actually the map of the Boston, MA public transit system, the MBTA. The words are not there, but the shape of the lines, and the colors are 100% accurate to Boston.
