When the sequence ends, access the DNA, and replay Sequence 4: Memory 8 - "An Unexpected Visitor" again. Once the sequence begins, skip it, and you will return to when you were offered the inventions. The first one selected will be grayed out, and you will have two options. When the sequence is over, repeat this one more time to get the final item.

Assassin's Creed reference

There is an achievement for solving all of Subject 16's puzzles. The name of the achievement is ".. .- -- .- .-.. .. ...- .", which is Morse code that translates to "IAMALIV." When spaced out, this is "I am alive." Lucy always maintains that Subject 16 died after writing on the walls inside Abstergo in the original Assassin's Creed. Additionally, this could also be a subtle reference to Ubisoft's game titled I Am Alive.

Assassin's Creed: Project Legacy reference

Successfully complete Sequence 6, then leave the Animus, and walk over to Lucy's desk. You will see two computer monitors. The monitor on the right shows the "Memories" section that you use to select your missions in the Assassin's Creed: Project Legacy Facebook game.

Metal Gear Solid series reference

In the "An Unexpected Visitor" mission in Sequence 3, during the task of finding the mysterious voice, the target will lead you to an upside down cardboard box similar to those used by Snake to hide under in the Metal Gear Solid series.

Super Mario Bros. reference

After you save Sforza from the Castillo, you will get the "Principessa in Another Castello" achievement, which in Italian means "Your Princess is in Another Castle." This is a reference to Super Mario Bros. and is similar to the Mario reference in Assassin's Creed 2.

Shop renovations

Renovate any of the five shops located in the Villa to increase the Villa's value and get special discounts. Each shop has three renovation levels. The blacksmith and doctor are available at the beginning of the game. The following is how much each of the three renovation levels cost for each shop:

Ant Merchant: 1,000, 5,000, 8,000 Florins

Doctor: First renovation already available, 3,000, 5,000 Florins
Tailor: 1,000, 2,500, 5,000 Florins

Finding feathers

Feathers are placed along the main quest areas of the game. This is unlike the flags in the original Assassin's Creed, which appeared seemingly at random throughout the world. Finding hidden feathers is best done by running across rooftops, since naturally that is where birds spend the most time losing them. Walk around the rooftops with Eagle Vision turned on to see feathers in a white glitch type of graphic.

To find the final few feathers, pause the game, and go to the DNA strand. There is a section at the end of the strand that shows you where the feathers are located. Then, go to the feather section to find out what districts the missing feathers are located in.

Easy medicines and throwing knives

Loot bodies or pick-pocket people to get free medicines and throwing knives.

Reusing axes and spears

If you lose an axe or spear inside an enemy while countering him, just pick up his corpse, and immediately drop it to be able to collect that weapon again and reuse it.

Giant squid

In the assassin's tomb in Santa Maria Delle Visitazione, before the room where you get one of the seals required for the Armour of Altair, is a large room filled with water. This room has an obstacle course. Activate the lever before going through the course, then stand on the edge of the floor, and look at the water. Remain idle until a large shape swims across the water. Use the lever again after the timer resets, and stand at same location. After awhile, a giant tentacle will shoot out of the water that Ezio dodges at the last second.

Easy kills

Once you unlock the smoke bomb, you can use it to kill guards quicker and easier. Equip the smoke bomb, then throw it. While the soldiers are coughing, use your hidden blade to quickly and easily kill them.

Using horses

The horses in the game can be very useful for things other than obviously using them for travel. Ride them into a potential fight and dismount. Lure an enemy to the rear of the horse, and it will kick them, inflicting a good amount of damage. They also will follow you after you dismount them until you enter a city, making them easier to relocate.

Defeating Archers

Normally Archers are not much of a threat and more of a nuisance, but in some areas there are a lot of them scattered around. If you are in a fight and there are also archers shooting at you, try to get away from the fight and run to the archer(s). This will make them drop their bow and draw their sword. You can also use the archer(s) to your advantage by positioning the soldiers in the archer's line of fire to have them wound the soldiers instead of you.

Defeating Brutes

Brutes are the large armored soldiers with two handed weapons such as axes and claymores. The trick to killing Brutes is to first disarm them. You can take their weapons away from them, and then kill them easily. Trying to reverse their moves will just result in you getting hurt if you have a weapon ready.

Defeating Seekers

Seekers are soldiers with spears. The trick to killing Seekers is grappling them. Grab them first to kill them quickly.

Defeating groups of enemies

When fighting a large group of enemies, it is best to keep moving around so they do not surround you and attack from more than one side at once. Keep your guard up, and wait for one of them to attack, then counter it. If there are Brutes or Seekers in the group, it is a little tougher, but the other tips listed will help. Try avoiding Brutes and Seekers at first and focus on the other enemies.

When you are in a situation where you have to fight multiple guards, attack with a group (thieves or mercenaries). While they are attacking someone, come from behind with your hidden blade to instantly kill them. Note: This also works during the final battle where many Ezios fight the final Boss; however, instead of using your hidden blade (because it is never successful), use your main weapon.

Defeating harder enemies

Note: This can only be done after learning the Disarm move. Sometimes you will run into the big "Golden Knights" or the men who fight better than normal soldiers and usually have unique weapons such as lances or big axes. They can also deflect attacks and counter more often. To defeat them more easily, disarm yourself by pressing Down to put your weapon away. When they attack, press X to counter and disarm them. This usually works in one attempt. Then, quickly press X again to kill the unarmed man.

Glyph locations and puzzle solutions

Use Eagle Vision to scan for Glyphs in the indicated locations:

The Truth File 1: While standing on a roof, it is on a wall at Santa Croce. Solve the puzzle by choosing the paintings with an apple in them.
The Truth File 2: While standing on a roof, it is on a wall at Ospedale Degli Innocenti. Solve the puzzle by rotating the circle puzzle pieces from smallest circle to largest.
The Truth File 3: While standing on a roof, it is on a wall at La Rosa Colta. Solve the puzzle by highlighting the circular object in each photo.
The Truth File 4: While hanging from the roof, it is on a wall at Villa Auditore. Solve the puzzle by taking the hints literally.
The Truth File 5: In the bottom dwellings of Santa Maria Assunta, it is on a wall near pillars. Solve the puzzle by choosing the paintings with a sword in them.
The Truth File 6: While standing on a roof, it is on a wall at Torri Dei Salvucci. Solve the puzzle by rotating the circle puzzle pieces from smallest circle to largest, while keeping an eye on the two outer layers that will connect.
The Truth File 7: While standing on a roof, it is on a wall at Torre Del Diavolo. Solve the puzzle by choosing the paintings with red in them; this can be done in any order.
The Truth File 8: While standing on a roof, it is on a wall at San Lorenzo. Solve the puzzle by finding the Pieces Of Eden (success is indicated with a sound). Then, put the flame over Joan on the world map. Finally, move Rasputin's photo to the top of Czar Nicholas II’s photo.
The Truth File 9: While standing on a roof, it is on a wall at Mercato Vecchio. Solve the puzzle by taking the hints literally, with the last one being 6=1.
The Truth File 10: While standing on a roof, it is on a wall at Monte Oliveto Maggiore. Solve the puzzle by not looking for the Eagle Apollo Lander on the moon. Once found, it is best to rotate the layers of the puzzle from the inside out until they all align, but note that inner layer 1 rotates on its own despite being connected to layer 4 in one instance; this also happens with layer 6.

Mario series reference

When Sequence 3 begins and you are escorting Maria and Claudia to the Villa, you will get ambushed by Pazzi and his men. You will be rescued by your Uncle Mario. When you first talk to him, he will say "Don't you recognize me? Its-a me, Mario!"

Easy "Doctor" achievement

Easy "Fly Swatter" achievement

Simply lock onto a target by holding LT and pressing X while in front of them to kick them. Note: This must be done during the Flying Machine mission to get the "Fly Swatter" achievement.

Easy "High Dive" achievement

Easy "Kleptomaniac" achievement

Find a herald to reduce your notoriety, and bribe him. This will cost 500 Florins. Once done, immediately pickpocket him to get the 500 Florins back, plus 3 to 5 extra Florins. Repeat this one more time with the same or different herald to get the "Kleptomaniac" achievement.

Go to Florence, and find a large group of people. Try to have them walking towards you. Hold A while walking through the group of oncoming people, and you should pickpocket most of them in just a few seconds. Since A also serves as the "fast-walk" command, you can get Florins quickly from people if you keep it held. Repeat this trick as many times as necessary to get the "Kleptomaniac" achievement.

Easy "Myth Maker" achievement

Easy "No-hitter" achievement

Unlock the Smoke Bomb, then buy three Smoke Bombs. Find some guards to start a fight with, and lure additional guards if necessary so there are at least ten guards. Throw a Smoke Bomb, and kill as many guards as possible with your hidden blade. Once the Smoke Bomb's effect wears off, throw another one. Repeat this until you get the "No-hitter" achievement.
