When Hellgate: London was released, gamers got to battle their way through a post-apocalyptic London overrun by demons, beasts and other nasty creatures. Those who paid a monthly fee, got a few perks and became subscribers to the Hellgate Chronicles.

On Monday, Hellgate Chronicles subscribers will be able to visit Stonehenge via a portal in the Templar Base. That portal leads to the Stonehenge hub, connected to three mini-raid areas. More importantly, Stonehenge is connected to four new dungeons (one for each creature type: Beast, Necro, Spectral and Demon), known as the “Caste Caves.” Finally, by completing the Caste Caves, players will be able to access Moloch’s Lair and defeat one of Hell’s foulest denizens (and access the unique loot he drops).
