PlayStation Vita game Assassin's Creed 3: Liberation is coming to Xbox 360, PS3 and PC as Assassin's Creed Liberation HD. The download-only release will not only benefit from updated graphics, but new missions and other enhancements as well.

An extensive Q&A from Ubisoft, available past the break, sums the improvements made to Liberation HD, touching on the new tutorial system, new combat (protagonist Aveline can dual-wield weapons now), polished free-running and improved facial animations and cutscenes. In addition to this, each mission has been "reworked" to provide better "pacing and challenge" for players. "And one more thing; we have worked heavily to improve the frame rate. The game will be smooth," says producer Momchil Valentinov Gindyanov.

AI and crowd behavior will also behave like Assassin's Creed Liberation HD's console brethren. "Using the AnvilNext engine and existing Assassin's Creed technology has really allowed us to push the crowd and AI behaviour," Gindyanov writes. "Liberation features all the crowd behaviour you've come to expect from an Assassin's Creed game, tailored to our own specific locations, so you can expect to see all sorts of activities unique to New Orleans, including Mardi Gras!"

Assassin's Creed Liberation HD is due on Xbox 360, PS3 and PC from developer Ubisoft Sofia. Neither timetable nor price has been announced.
