Assassin's Creed 2 Walkthrough

You've got a limited amount of time to complete this fairly challenging obstacle course. A series of waypoint show up one after the other, and you've got to run through all sixteen of them, quickly. The first four are on ground level, so you don't waste time climbing any buildings. The fifth waypoint will start you on an ascent up the side of a building, and from then on you can expect next bunch to require some careful platforming as you skirt the side of the building.

After hitting the seventh marker, turn left and jump off the ledge of the platform. Ezio will grab onto something hanging just off screen and swing around to the next series of stepping spots and their waypoints. You'll eventually have to climb up to the rooftops for a couple of waypoints.

On your way to the thirteenth waypoint, you need to take a big dive off the west end of a building and fall into the river below. Continue up the ramp to the street level and you can continue collecting the last few waypoints on street level. The final marker is on a boat.

This is a simple mission. You need to just fight off the opponents that come at you using your bare hands. Even though you've no weapon equipped, you can still use the typical counter ability. Though you won't always KO an opponent with the first counter, repeatedly make use of the technique and you'll eventually drop the opponent.

Eventually, some sleaze will send in dudes with swords. At this point, it's a-okay to break out your own weapon and fight back, though it's certainly not necessary. Defeat all of the opponents and the challenge ends. That should be the last of the carnival games!
