While it's a CGI trailer, and therefore no in-game footage, it does help Witcher fans to see the Wild Hunt is full of all kinds of monsters that need a Witcher's blade to sort it out, or not.
"'Killing Monsters' portrays the cruel and gritty world of The Witcher and foreshadows the mature mood of the upcoming story-driven RPG," blurbs the official description.
The Witcher 3: Wild Hunt releases on PC, Xbox One and PS4 in 2014.
