Recently, I have been re-playing the Assassin's Creed series, in an effort to better understand the story before I get syched up for Assassin's Creed III.
Naturally, I began with the first Assassin's Creed. I was sprinting through the streets aimlessly, when I noticed something quite interesting.
I'm not sure if this has been brought up or noticed before, but when starting a free-running sequence on a box of crates (or perhaps a cart), Altair has the ability to slide on his backside and fall off of the end! (Landing on his feet, of course). This can be done by pressing A (or square on PS3) and B (or circle on PS3) simultaneously, after you have begun the sequence, and are nearing the end of the crate or cart. As I have said before, when this is done, Altair appears to be "sliding" off of the object he is about to jump from. I have tested it numerous times, and I have been succesful in executing it every time (that is, as long as I timed it correctly, but it's not too difficult). It also works on some buildings, but not on most.
As I said, I am not sure if anyone has discovered this before, and if that is the case... Merda.
