During game play press A, B, X, Y, Right Trigger, Right Bumper, Left Trigger, Left Bumper.
When you are in any city and you are jumping from roof to roof, you might run into a few guards. If you have the ability to throw knives, just get him in straight view, then equipped your short sword (it has the knives equipped with it) and click X. If it hits the guard, he will die. But if you miss, he will engage in combat and attack you so aim well before throwing!
To easily kill guards, throw one on the ground, and then repeatedly attack them with your sword.
When fighting guards, all you have to do is grab them and throw them on the ground. Then pull out your silent blade and you can assassinate them without them being able to block your blow.
When you fight, hold down RT (Right Trigger) to produce a defensive stance. Wait for the enemy to strike, and when they are about to hit you, press X (Blue Button that has an X on it) to deflect the attack and usually kill them instantly. If it doesn't kill them instantly, it will knock them down. This style takes a few tries to get used to, but when you get it, you become unstoppable.
If you have mastered the skill counter and know when to strike then select your hidden blade. Be warned it does not protect you from strikes. When a guard is taunting you go up to him and kill him you will jump on him.
If you ever want to quickly defeat a guard all you have to do is grab the guard and throw him into a merchant stand or wooden platform. It will instantly kill the guard and sometimes other guards standing by it as well.
In the game their is a boss who plays the actual boss that you fight later on in the game. In order 2 beat the boss you need to keep your distance because their is an army that is almost unstoppable. Use your throwing knifes until you run out, then finish em off with the short blade, it works.
When in a battle select the hidden blade and when they attack hit counter and its an instant kill if done properly.
After you complete the game. You can go to any town and kill any citizen without a penalty.
When you kill a guard or a bystander, a guard will start to walk toward the nearby corpses. While he is walking switch to your hidden blade and you can take him out easily and no one will notice. If he gets to the body and asks "who did this", then don't attack him because he will block your attack and throw you away and you'll have to fight him and that might attract unwanted attention.
