Ubisoft two DLC packs for Assassin's Creed II
today. The first is titled "Battle of Forli" and will be released in January, 2010. The second is called "Bonfire of the Vanities" and will ship in February 2010 and probably not feature Tom Hanks or Bruce Willis.
Ubi didn't provide pricing or information on what is actually in the packs but did mention that each pack will take up about 1 GB of hard drive space and will require the original disc to run.
