It won’t be that complicated, but there is still a process that must be navigated to unlock and obtain a guild hall. As part of its Guild Week, ArenaNet outlined the steps that must be undertaken for group housing. After players check in at Lion’s Arch guild initiative headquarters, they’ll mount an expedition (which costs 100 gold) into the jungle to find and conquer a whole bunch of Mordrems. If the expedition is successful, guilds can then start building and upgrading facilities.
You can watch the full 37-minute discussion of guild halls and associated features in yesterday’s livestream after the break.
