Today, we get the real thing. 1UP has footage of their demo available, and it's a human vs. earth elemental battle on a pretty grand scale.
That's not the only news coming out of Cologne this morning, though. Spong.com is reporting in a brief blurb that Colin Johanson told them that the necromancer is indeed the next class to be revealed. While ArenaNet has not announced this anywhere, in the demo video you are able to hear the necro class and a few of its abilities mentioned.
Follow along after the jump to see the demo firsthand, and don't forget to keep an eye on NCsoft's live feed from Gamescom!
