In the mid year update it was written:

"We’re also still working on our Guilds System to build upon this already strong community, along with a host of incredible tie-ins around Iron Maiden’s upcoming Legacy of the Beast Tour - we’re super excited about this awe-inspiring spectacle that was inspired by our / your game and have a suitably epic schedule of new characters and events coming to support the tour from the moment it kicks on the 18th July in Florida \m/"

So how is the guild feature coming along? Will it be available sometime before the tour ends or after?
