"I will bring each citizen to safety" challenge
Ok guys, as promised, a new challenge :
- put the normal clothes (not Borgia's) and set your notoriety at the maximum
- go either to the south-west, south-east or north-east corner of the map
- chooze a citizen and knock him/her down (no kill would be better)
- put the body on Ezio's shoulder
- reach the stairs (shown on the picture below) without dropping the body and without any help of the recruits
Had a go just now.
Bottleneck is the bridge at the Castello. All the other guards can be evaded. The only option I see without dropping the body is killing all those guards beforehand. I think they'll respawn, though and if they do, the challenge is pretty much undoable until someone finds and exploit to stay blended with a dead or unconscious man on your shoulder. 
I already tried killing those guards beforehand, but they respawn too fast. Can't think of any way to get past the bridge either.
The papal guards would be also a problem, but I think that they disappear completely (at least if you don't have any loading screen in nothingness).
I think you can get past the previous bridge by studying the guards' movements, and by using the environment to hide. Also some luck manipulation could be used so that there's no citizen on this bridge.
Remember that "I am the master of the world" would have normally been impossible too 
Its hard enough being incognito with a limp person on your shoulder. Lol
Let's do this.
Also, notoriety doesn't matter, since guards will attack you immediately on sight if you have a dead/unconscious body over your shoulder, whether you're incognito or not.
I don't know how this can be possible without recruits at least. :S

I don't think it will work while carrying the citizen. It is fairly easy to do that otherwise because you have a few seconds to hide after the guards notice you, but with the citizen they attack on sight.
I think we ought to try it anyways.
I think that using a single assassin signal (and no more than one) would make this fairer.
Heyhey, noone stopped to think about the mercenaries/thieves/courtesans? 
Of which there are none in Il Vaticano, if I'm not mistaken.
Not in Il Vaticano, but there are no guards on the ground in Il Vaticano, except for the 4 papal guards.
How I understood the mission was that you should walk from the old French quarters/Place where Leo likes to sit/Thieves guild to the stair in the Vatican.
Walk or run, but with a body on Ezio's shoulder the whole time
Exactly, Slem. That means you can pick up courtesans/mercenaries/thieves on the way to Il Vaticano.
