Like the title says, a shortcut for silently killing all the guards in the Sistine chapel. Here's the original video.
The only weapon you need equipped for this is poison. I start with the brute at the upper left of the room. Blend-walk out of a group to poison the brute without getting detected (stick by the wall to avoid getting seen by the other brutes). Now walk along the wall and poison the other brutes on that side of the room from behind. After that walk straight across to the other side of the room. The brutes there will see you until you blend back into a group. Blend-walk out of that group and repeat the process. The last brute is blocked off by a structure, so I run to poison him. You can expect for him to exclaim from seeing you, but usually he's poisoned when you're still anonymous.
Now for "killing" Rodrigo. Here's a way to "kill" him with one of the brutes' weapons. This will cause a glitch (not shown in video) with the scene after the memory corridor scene. This glitch was shown before in a video.
However it was done with a heavy weapon outside of the Chapel. It was originally thought you couldn't kill him with a weapon in the chapel. This is because you have to jump from the high place and immediately attack. Running at him with the weapon and attacking will result in desynchronizing during the kill animation. So here's what to do: At the place shown in the video do a wall run and grasp the structure. There's a good chance the weapon will get stuck in the structure. Now climb on the ledge at the place shown, which will have Ezio in a standing positon. From there you can pick up the heavy weapon (make sure you're past the corner of the structure or Ezio will grasp the structure when you press the ). Now you can make your way to the high place without having to drop the weapon. You can probably also use this method to bring the papal staff out of the Sistine Chapel.

Upward Mobility is an assassination in sequence 13 Florence. Basically you chase the target while some guards come after you.
The fastest way to kill this target (without even moving!). At the beginning of the assassination mission the target is close enough to lock on to. The game switches your weapon to fists after the cutscene, so you will have to bring up the weapon wheel right away. After that simply lock on and shoot. I did not use throwing knives because Ezio will automatically throw them at the guards coming at him.
For this mission you are detected right away. I avoid this by bribing a herald to teleport me away from that spot. Now when I start the mission I am anonymous. However you become detected when you have a clear sight of the target, making it near impossible to kill him while remaining anonymous. I do the next best thing- remain unseen by any guards that are alerted to me. When I am first detected the minimap is yellow, indicating that the alerted guards haven't seen me. Right afterward I blend in with a group of thieves and go into superblend to be hidden. I messed up a little and almost desyncronized, but it all eventually turned out good with an in-your-face assassination that had a nice result.

A quick way to eliminate most of the guards in this mission while remaining unseen is to hire the mercenaries to fight for you. Guards will automatically join in the fight if they can see the battle, so all you have to do is get the battle started in a central location.
This video demonstrates a weird glitch with AC2 that allows you to finish the Francesco Salviati without killing him, and without the post-assassination cutscene.
At the end of the mission, Francesco simply vanishes in thin air, and the mission is complete.
Start off by using the passing crowds to hyperblend on the horse. If you are not familiar with superblending and hyperblending, please see these articles first:
After you leave the area, the gate to the compound is no longer modeled in the game. The developers forgot to put it back in place when you return. This mission is loosely related to "There is no spoon"-type missions:
Still Life - Dynamic Stunt
The target circles around the yard untill he sees something suspicious, at which time he flees to a waypoint on the south side of Palazzo Pitti. This gives a brief opportunity to perform my favorite type of stunt - where both you and the target are running full speed toward the stunt location.
The five targets in the Meeting Adjourned mission are dispersed in a small room with many guards, which makes this mission seem like an unlikely candidate for anonymous poisoning. Fortunately, the developers made an unusual choice in the design of this mission: The room is not a high alert area. Instead, they elevated the awareness levels of the targets so that they behave as if you were Notorious, which is functionally similar to making the room a high alert area - except that the developers did not change the guards in the room correspondingly. As a result, the targets and guards behave differently in this mission, which is what I exploit in this mission design to poison all of the targets while remaining unseen (no yellow bars) to all of the guards.
This contract is slightly harder than the others when going for stealth. If you get anywhere near the guard, he will run. Also, if you kill any guards behind him without him seeing them, he will still run.
