Besides that hidden blade you've fashioned for yourself out of old rollerblade bearings and a letter opener, there hasn't really been a great way to get the feeling of Assassin's Creed 2 while on the go. Sure, there's the Nintendo DS game, the first AC on iPhone, and the limited time accidental release of Assassin's Creed 2: Discovery a few weeks back, but now we've finally got an official release date of February 1 for the DS-to-iPhone port.
Like the DS game, Ezio's adventures on the iPhone will take him to 15th-century Spain where he's tasked with rescuing assassins that are "being held under the guise of the Inquisition," when he learns of "a Templar plan to sail west and discover the New World." What a bunch of discoverers those guys are -- sheesh!
