Assassin's Creed 2 Walkthrough

Find Rosa and Antonio and you'll have to wander around the Palazzo Ducale to scout out a way to infiltrate the building. Lead Antonio to the first map marker for a quick bit of dialog. Another map marker appears.

Run to the second marker to scout and a third marker appears to the southeast. Beware that the building is surrounded by a restricted zone, so do your best to skirt around it. The third marker is at the top of a tall tower that you must climb. It's not a tough climb, but the way back down can be tricky unless you use the leap of faith off the north ledge.

After the leap of faith, wait around for Antonio to catch up—he's afraid of heights and won't leap after you. You need to now make your way to the north end of the Palazzo to hit a fourth map marker. Again, be careful to avoid the restricted zone's boundaries as you go around the western side of the Palazzo. When you hit the map marker, Antonio suggests that you've found a suitable route to the top of the building.

A fifth map marker guides you onto the top of the Palazzo. Climb the northern face of the building, using the scaffolding to bridge the gap between hand holds. When you reach the top, make your way to the map marker. There are no archers to worry about, so just hit the last waypoint to end the mission.

Find Leonardo's new shop in Venice and pay him a visit. He and Ezio move to a rooftop to test out Leo's rad flying machine. As the cut scene ends, you get to play with the flight controls a bit. You don't really have to do anything—in fact, we crashed into the first building we came to (...the controls are inverted...). After you've landed or crashed, the mission is over.
