Throughout the game there ar 20 symbols which Subject 16 had hacked and put on the Abstergo Memory Core stolen by Lucy. They remain in the same location throughout the game. It takes a lot of time to find all these symbols once you can see them with Eagle Vision. You must complete a series of mini-games for each symbol. Subject 16 says that after you find all twenty symbols and decipher them, you will see and understand the truth. Note: The symbols are not all on the ground level and are at random locations. Two are in Tuscan (one of which is on the third floor of a viewpoint). Another is on the top left of the Assassin Home. There is also one in a stone place where Rodrigo betrays his man that you kill. It is under a wall on the side.
When you knock into a person with a broom or mop, pick it up. The broom or mop will act as a mace, hammer, or other blunt weapon. It makes it seem as though you are cleaning up the trash. Note: This can also be done with farmer's garden hoes.
Usually Archers are less than a threat and more of a nuisance, but in some areas there are quite a few of them scattered around. If you find yourself in a fight and at the same time there are archers shooting at you, try breaking off the fight and running to an archer. This makes them drop their bow and draw their sword. The funner approach is to position the soldiers in the archer's line of fire and have them do your dirty work and hurt the solders attacking you.
There are a couple things you should get before you go to Rome: The Armor of Altair, The Sword of Altair (or whichever weapon you prefer), Notched Cinquedea, Metal Cestus, both knife belt upgrades (as many as possible), medium and large medicine pouches (purchase as much medicine as possible), and full smoke bombs. The battle is divided into three stages. The first stage involves assassinating him. Quietly go down the ladder, but do not jump down. Then start blending in with everyone immediately. Go to the front, choose your pistol, and lock on to Rodrigo. Hold [Action] until the thin beam appears and fire. In the second stage you must fight him. You sit back and wait for your four Dopplegangers to finish or at least weaken him, but you can also join in the fight--which is much more exciting. He attacks just like a brute; just tackle him as you would a normal villain. In the third stage you must complete the job. After the cinematic sequence, use Eagle Vision to find the switches to the vault. Follow the road down. Another cinematic starts, after which it is a fistfight from here on out. Continue attacking him. The Metal Cestus will stay equipped and will kill him faster. Follow the onscreen prompt to finish the fight

1,500, 5,000, 9,000 Florins.

Brutes are the big armored soldiers that wield two handed weapons, such as axes and claymores. The trick to Brutes is to disarm them. Trying to reverse their moves will just result in you getting hurt if you already have a weapon. You can take their weapons away from them and then kill them easily.
When fighting big groups, keep moving about so they do not surround you and attack from more than one side at once. The trick to fighting the group then is to keep your guard up and wait for one of them to attack and counter it. If there are Brutes or Seekers in the group, it will be much tougher. Try to avoid Brutes or Seekers at first and focus on the others.
Use the following trick when you are in a situation where there are multiple guards, attack with a group (thieves or mercenaries). While your friends are attacking someone, come from behind with your hidden blade and end them. Note: This also works with the final battle where many Ezios battle the final Boss, though instead of your hidden blade (because it is never successful), you will need to use your main weapon.
Note: The Disarm move is required. Occasionally you will run into the big "Golden Knights", or the men who just fight better than normal soldiers. These opponents usually have unique weapons such as lances or big axes. They are also capable of deflecting attacks and countering more often, resulting in you being killed. To take them out more easily, simply disarm yourself. Put your weapon away by pressing Down. When they attack, press X to counter and disarm them. This usually works in one attempt. Immediately press press X again to kill the unarmed man.

Horses are very useful. Other than the obvious use for travel, they can be ridden into a potential fight and dismounted. Lure your enemy to the rear of the horse and it will kick them, inflicting decent damage. They will also follow you after you dismount them until you enter a city, making them easier to relocate.
You will start the game with only the ability to go between cities or other locations via a horse. This becomes difficult once more locations are unlocked and you have to go back and forth between them often. You will be able to unlock and use fast travel stations in the game. These also appear on the map to make finding them easy. Using this option does have a cost of 100 Florins, but it is worth that amount to transport to your destination instead of a lengthy horse ride.
Go to the assassin's tomb and find the large water-filled room before the room where you get one of the seals required for the Armor of Altair. This room has an obstacle course. Activate the lever before going through the course and stand on the edge of the floor, then look at the water. Remain idle until a large shape swims across the water. Use the lever again after the timer resets and stand on at same location. After a moment, a giant tentacle will appear.
Find a herald to reduce your notoriety and bribe him for 500 florins. Once done, quickly steal from him. You will get the 500 florins back, plus 3 to 5 extra florins. Repeat this one more time, either with the same or different herald, and the trophy will unlock in seconds.
Go to Florence and look for a big group of people.Your goal should be to have those people walking towards you. Hold A and walk through this group of oncoming people while pickpocketing them. Since that button also serves as the "fast-walk", you can quickly get florins from citizens if you keep it held.
On the Red Handed Templar Agent mission, there is a shovel near Ezio. You can pick up this shovel and use it to attack. However, there is something wrong with the animation as Ezio will hold the shovel reverse handed.

When Sequence 3 starts and you are escorting Maria and Claudia to the villa, you will be ambushed by Pazzi and his men. You will be rescued by your Uncle Mario, whom will say "Don't you recognize me? Its-a me, Mario!" when you first talk to him.
Notoriety is essentially your wanted level; the higher it is, the closer to notorious you are. Notorious is where guards take one look at you and say "Get him!". You want to keep the symbol of a head inside the gauge white. Gaining notoriety is easy; simply do criminal activities, assassinate in front of people, kill guards in general, run across rooftops, and even just bumping into some guards by accident. Losing notoriety is also easy. The game tells you the three methods of losing it: bribe heralds, rip down posters, and kill officials. The posters is the easiest since they are everywhere. However, because of that, they also give the smallest returns (up to 25% of your notoriety bar per poster, or four posters if you are notorious). If you are that bad off, four posters can seem next to impossible. However, you will be jumping about a lot anyways andare bound to find a couple of them. The second method, heralds, is your middle ground, but it comes at a price: 500 Florins for up to 50% of the notoriety bar. The cost is 1,000 Florins if you are notorious. Do not be dismayed by the cost as that cost turns into a very slight profit. The last method, the officials, give the best return, but are also difficult. Like the thieves and couriers that you chase down for cash, they run everywhere once they see you (up buildings, across beams, through crowds, and most especially towards guards). The reward is 75% of the bar for an official, but the time spent could have been better used ripping down posters and bribing heralds.
