The Korean Hellgate site HG.Gamemeca.com has posted what appears to be two new concept artworks for Hellgate: London. As far as anyone knows, it could just be two pieces of art with the Hellgate Logo on it, so officially these shots should be considered a rumour still (even the poster at Gamemeca speculates so). Still, the past experience concerning Gamemeca, would imply that it is likely new concept art for Patch 1.3. The art style is also very similar to previous concept art.
