Footage of Dragon Age: Inquisition has leaked online in a massive 30 minute video of off-screen gameplay.

The footage was captured at Finnish show DigiExpo, and has actually been on YouTube for over a week without being removed.

It's believed the pre-alpha gameplay is the same content shown to press back in August, which at the time was running on a high-end PC with an Xbox controller.

Dragon Age: Inquisition is being developed at BioWare Edmonton and Montreal studios using Frostbite 3. The game is scheduled to launch in autumn 2014 for PC, Xbox One, PS4, Xbox 360 and PS3.
