Today Ninja Theory released a video of Hellblade Director Tameem Antoniades' talk at DICE 2014, and he dropped a very interesting detail about the old and glorious Heavenly Sword, a sequel of which many would still like to see:

We were the first studio to use performance capture in a videogame with Heavenly Sword way back in 2005. we developed our real time systems in collaboration with Weta Digital. And I was actually there at Weta, stood next to Peter Jackson when he was demonstrating the real time performance capture tech to James Cameron using Heavely Sword assets.

Antoniades also explained that since then the tech has spread like wildfire in the movie industry, but it's not yet as widespread in the gaming industry. Apparently many studios believe it's too costly and complex. On the other hand he feels that it's the quickest and cheapest method of producing cutscenes, and thanks to a collaboration with Vicon (the largest manufacturer of performance capture equipment and software) Ninja Theory wants to prove with hellblade that it's possible to use the tech with a modest budget.

Ninja Theory also plans to share their results with other studios to help the spread of the technology in the gaming industry.

Personally, I'm definitely curious to see the restults. Hellblade seems more and more interesting every time I hear about it.
