The surprise might have been ruined, but Game Informer's premature preview of Assassin's Creed III: Liberation still couldn't kill the enthusiasm for PlayStation Vita's biggest E3 announcement.

For the first time in the Assassin's series, Liberation introduces a female assassin named Aveline. The game – which is a brand new adventure designed specifically for Vita – takes place in eighteenth century Louisiana.

Aveline herself is described as a “uniquely effective assassin” who takes advantage of weapons such as machetes and poison-darts.

The game's set to release alongside Assassin's Creed III on 30th October. Even better, if you play both games you'll unlock some additional goodies in Liberation, including Connor's tomahawk and an exclusive character skin.

If you don't already own a Vita, you'll be able to buy Liberation as part of a hardware bundle, which includes a crystal white system and a 4GB memory stick in addition to the game.
