There is a new gameplay video up at a German games site. It appears to be a video recording of a game demo Fabrice was giving. The video is large (~140mb) and long (20min) and it is somewhat difficult to see what's going on as it is a video of a computer screen, but there is lots of information in there. The demo focuses on the necromancy theme and the underground terrain is also shown off for the first time.

Note: To download the video click on "downloaden starten" then right-click/save as on the link which appears to the left of the pop-up. You don't need to stream it.
