Ubisoft UK tweeted today that Assassin's Creed Liberation HD will release for the PC and Xbox 360 through the Xbox Marketplace on January 15, 2014. It will release for the PlayStation 3 through the PlayStation Network on January 14th. Since this is from Ubisoft UK, we assume that these dates are just for Europe and not for North America as of yet.
The HD remake will cost $19.99.
This new HD version is an upgraded version of the Vita exclusive. It will include the same story, but the features have been improved for consoles as well as the visuals.
