BioWare is at Comic Con San Diego, and they have brought some more demos to the fans. So far they have been showing us the already well known demo with the female Qunari mage, but it seems they decided to show us what it's like with a male human rogue Inquisitor this time. One of the newest features seems to be the throwing knives, which has been available only for Tallis in previous installments. Other than an introduction to the dual wielder rogue gameplay, however, the areas and enemies are the same.
The video is of low quality as of yet, if there will be a video longer and of better quality than this, it will be updated.
Thank you Star Metal Knight for this great catch!
