Memory 3: End Of The Road

You'll start by pushing enemy carriages onto rocks. Focus on this maneuver rather than direct combat; the environment will do most of the work for you. Avoid the rocks yourself, and the enemies will eventually be defeated.

After dealing with the carriages, you'll face Ahmet. The game will prompt you to open your parachute. Take a moment to get used to its controls, as you'll need them to navigate the upcoming section.

Your main objective now is to protect Sofia and her carriage. Avoid trees and buildings while flying. If you take too much damage, use medicine to heal yourself.

Horseback Templars will attack Sofia. You'll need to assassinate them using the swooping assassination attack. If you have good aim, you can also grab a Templar and throw them at another horseman, taking out two at once. There are plenty of Templars (at least 30) to take down, so keep at it to meet the full synchronization requirement of killing 20 guards.

After a cutscene, you'll need to block by holding [R1/R], even if the game doesn't explicitly tell you to. When Ezio is on top of Ahmet after rolling, press the attack button to punch him as you fall. Keep attacking to trigger another cutscene and end the memory.
