One of the quiet hits of Gamescom so far has been Wildstar, a freshly-unveiled MMO from NCsoft. While it won't be of much interest to anyone outside the world of MMOs, it does have a great art style, and its blending of fantasy and sci-fi design (along with BRIGHT COLOURS EVERYWHERE) making it very easy on the eye.
In this footage you can see one of the developers kill a lot of space sasquatches. Like, that's nearly all you're going to see: 2:30 of a man killing large animals. So at the very least, you'll get a good idea on how the game's combat works!
