We've always expected that the Hellgate: Tokyo expansion content would be coming to T3Fun's Hellgate Global sooner or later (the South Edo zone pretty much confirms it), but now a single new screenshot on the game's Facebook page with the caption "The demons were not satisfied with London. They have spread to the four corners of the globe." seems to indicate that we'll be getting the add-on in the near future. That's certainly good news, as it means new quests, new zones, new monsters, new bosses, and, of course, new equipment are all inbound.
And for what it's worth, the company has also kicked up a new thread on their forums in order to track down the bugs that are plaguing players within the open beta.
