Update: Also as we heard before, our new assassin's name is Aveline, a "woman of conviction." The game takes place in 18th century New Orleans, and will take advantage of the Vita's suite of unique input methods to provide "distinctive combat, character interaction, deciphering and traversal controls." Multiplayer has also been "tailored" to the Vita, though no further specifics were given.
Specifics were given, however, on the game's PS3-unlocked goodies, which include "an in-game version of Connor's tomahawk, an exclusive character skin, a multiplayer character and a complete upgrade of all ammunition pouches."
