You can use this gamesave to get the 'Dust to Dust' achievement in Assassin's Creed Brotherhood because you can miss it if you complete the games storyline, just follow these steps for the achievement:

1. Download the Dust to Dust Achievement.zip file and extract its contents (there are two save files and I wasn't sure if you need them both or not so I just put both in there)
2. REHASH/RESIGN both with your ID's
3. Load the save up on your console
4. Once loaded, pause game and leave the animus, go outside of the sanctuary and find an artifact, there are 5 of them, the easiest is at the very top of the building you come out of
