I'm really interested in this font coz it's using in Russian localization of Assassin's Creed II and Assassin's Creed: Brotherhood. In English versions of AC2, ACB and ACR the font is Aaux Pro. For ACR was made cyrillic symbols (I've created it by myself for me) In AC2 and ACB the fonts are the same, but aren't Aaux. I've been looking for it for very much time. If you will have to need in other samples, i will send them to you.

Sorry for bad English, I'm Russian
