Hellgate is a strange game for a number of reasons. First of all, it’s a weird amalgam of singleplayer and massively multiplayer. You can tackle its main quest alone, or you can band together online.
Secondly, many of its side missions and locations are randomly generated. You might set out for the British Museum to pick up a sacred artifact but discover a portal to another dimension down a drainpipe. Finding these random side-missions is part of Hellgate’s thrill: knowing that in a few seconds, you’ll be showered in special loot.
