Assassin's Creed 3 getting PS3-exclusive DLC

Assassin's Creed 3 will get PlayStation 3-exclusive DLC at the game's release, Ubisoft has announced, after demoing an impressive new naval warfare section of the game.

The deal is similar to how Assassin's Creed: Brotherhood on PS3 got the Copernicus Conspiracy mission on day-one, too.

Freshly-leaked PlayStation Vita title Assassin's Creed 3: Liberation has also been revealed by Ubisoft, live on stage at Sony's E3 press conference.

Liberation is an entirely separate game to Assassin's Creed 3, featuring a female assassin in New Orleans.

The game will offer a "complete open world experience", support touch-screen controls and social functions through Near.

Connecting Liberation with Assassin's Creed 3 will unlock AC3 hero Connor's tomahawk, an exclusive player skin and several other in-game upgrades.

Liberation will also be offered in a new PlayStation Vita bundle, with a crystal white-coloured console and 4GB memory card.
