Assassin's Creed 2 Walkthrough

Hit the map marker and this mission will immediately kick off. You need to check the nearby street in front of a large, regal building to find a certain somebody. The area is marked green on your map, so don't waste time anywhere else. Just turn on eagle vision and, once you've spotted the target, a cut scene will take over.

After the cut scene, you need to defend Lorenzo de'Medici, who's marked with a blue arrow. Move near him before readying your sword. If you see an enemy attack Lorenzo, you can frequently score instant kills with a stab to the enemy's back. Otherwise, just stay near Lorenzo and catch enemy attacks with counters for quick kills.

When the enemies are dead, you need to escort Lorenzo across town. The escort is pretty straight-forward, just run toward the map target with Lorenzo in two. He'll keep up with you in you run, so book it, doing your best to ignore the men fighting around you. If you do get confronted, be ready to defend Lorenzo as you did before, putting yourself next to him so that you can counter incoming attacks. When you bring Lorenzo to the end point, the mission is complete.

Talk to the indicated man and he'll tell you that Francesco is mounting an attack at some tower across town. Take to the rooftops and start heading for the tower. There's a waypoint on top of a building overlooking the courtyard outside the tower—hit it and you'll see a cut scene in which Francesco sics his men on you.

Well, not really—no one advances on you. You need to get to Francesco, who's standing atop the prison tower. The northeastern corner of the building is probably the easiest to climb, and you can get a boost from the adjacent building. As you ascend the tower, you'll run into enemy guards. Do your best to ignore them. While you can certainly stop and fight if that sorta thing suits you, it's not necessary.

You want to get to the top level and approach the northwestern corner to trigger a cut scene with Francesco. He'll immediately dive off the corner of the building, prompting you to take a leap of faith off the same corner. Don't worry, you'll survive. When you land, lock onto Francesco and chase after him. Equip your hidden blade and, when you get close enough, launch an assassination attack to end the mission.
