DNA sequence 3 consists of 5 memories.
Roadside Assistance (Monteriggioni, 1476)In this memory continue walking with your family until you are ambushed. Once ambushed take out the guards, your Uncle will then appear and you will be given a sword. Once you take out the remaining guards a cut scene will play and this memory will be synced.
Casa Dolce Casa (Monteriggioni, 1476)This is a really easy memory. You will be tasked with following your Uncle around while he tells you about the city. You will eventually end up at the manner and he will give you some money to buy things in town. First you must buy a dagger and greaves from the blacksmith and then some medicine from the doctor after that the memory synchronizes.
Practice Makes Perfect (Monteriggioni, 1476 - 1478)This memory is all about learning new skills and when learning them you must perform them
3 times. First you will learn
Quickstep this is done by pressing
and using
to decide your direction
(quick tip: you will want to press the buttons near the beginning of his swings windup.) Now it will teach you
Counter Kill which you must hold
and press
as he swings. Third skill is
Taunt which is as simple as pressing
(this is great for enemies always blocking.) The last skill is
Escape which can be performed by holding
while locked on. You will then have to prove your worth by fighting your Uncle, it is super easy to just counter his attacks, once you beat him a cut scene will roll. After the cut scene you must walk to the manor to go talk to him, once at the way point interact by pressing
and synchronizing this memory is finished.
What Goes Around (Tuscany, 1478)For this memory you must help your Uncle assassinate some people. Follow your Uncle to the castle walls and climb up using the crates. Once up equip your throwing knives by pressing
to bring up the weapon wheel and use those to dispose of the two guards quietly. Now jump down and activate the gate by pressing
at the interactive object, kill the guard that runs at you and then go outside to help kill the rest. Once inside Mario will send you with some soldiers to kill the guards up the stairs a little ways and after doing so a way point will appear. Walk to the way point and interact with the soldier, move up into the plaza and help take out the guards attacking the rest of the soldiers. You will now be asked to find and kill Vieri, run to the way point and a cut scene will play, after that your Uncle will attack the guards and you have to go kill Vieri. He is located on the castle walls which you can climb just a bit back along the inside wall, once up there dispose of the guards and him and another cut scene will roll and with it the memory will synchronize.
A Change of Plans (Monteriggioni, 1478)In this memory you must once again follow your Uncle Mario, after that you must read the letter from Fra Giocondo
(funny note: sounds like a eco-friendly condo.) Once you have read that you must go and meet your Uncle at the way point and you will learn about the
Codex Wall. Now climb up the manner and synchronize the viewpoint which will reveal
4 Codex Pages that you must go and collect, quite simple using the map and once you collect the fourth synchronization is achieved for this memory
Once memory is synced the achievement should pop.
