Long ago there was a small group of people from blizzard who made diablo2, that also made a game called hellgate london.
they made the game, and had it online, but i think couldn't get some rights to somethings plus they were not makeing much profit.
so the game is just single player now.

i just googled it today 4/20/2012, and i found hellgate tokyo... which is the new one!!!!!!!!!!
