Blindly go where world's first has gone before? Start time flexible. All slots reserved up front for members of the Blind Brotherhood, but there will likely be space (they've had enough of me!) so feel free to reservify if you're interested
The game creator, Azrael n Sasha, should send out invites 5-10 minutes before start time. If you don't receive invites, the creator may have left so start inviting each other through xbox/psn/pc on your own.
