The Hidden Blade Assassin's Creed in Depth

The concept here is simple: assassinate Philip Twopenny by throwing him down an elevator shaft. There are actually two empty shafts in the Bank of London which lead down to the vault: the "secret passage" that you must find for 100% sync, and another in the northwest corner which only opens if you kidnap the head of security. I used the secret passage because it can be reached without going outside.
