Even if you haven't been sucked into the MMORPG Guild Wars 2, you can appreciate this breathtaking concept art for their Halloween update. Craig Pearson at Rock, Paper Shotgun has the details:
The Shadow of the Mad King update will bring a new four-part story based around the returning trickster. The figure of folklore will be spreading insanity and mayhem through Arenanet’s lovely MMO from October the 23rd all the way to the 31st. In addition, there will be themed costumes and items to buy, as well as a Costume Brawl event. I suspect if the art is anything to go by, Guild Wars 2 will be the gaming equivalent of the man down the road who spends all year planning his holiday scares.
