Assassin's Creed 2 Walkthrough

Wait, you don't have Sequence 12 or 13 in your game!? Neither did we at first. Ubisoft released the two missing sequences as downloadable content months after the game's release. If you want to play them, you'll have to download them.

Talk to Caterina in Forli and you'll begin escorting her to the city entrance. En route, expect to be intercepted by a small contingent of enemy guards. Fight 'em off with the help of Caterina's men and continue to the city's northeast entrance.

Caterina tells you of a secret entrance on the other side of the city. Head west, through the water, and ignore the battle that's unfolding on the northern docks. You can skirt the fight and still gain access to the row of free-run-friendly poles that run around to the west side. There's a gate that'll stop you from rowing a boat into Forli, but you can duck underwater to break in.

Start running back toward the east end of the city, doing your best to ignore the ongoing battles and avoid gaining any unwanted attention. If you get spotted, you'll likely have to fight, so be ready for it. When you reach the next target marker, look for a ladder to the right of the main gate and follow it to the parapet walk.

From here you can climb over the rooftops to reach the lever that opens the gate. But before you drop down to pull the lever, position yourself on the wires directly above the two guards that are overlooking Caterina and her posse below. You can perform a double assassination to take them both out, allowing you to unlock the gate in peace.
