From the announcement:
MiniWarGaming and Black Knight Games are hosting a massive Warhammer 40,000 Apocalypse Game: Apocalypticon, and you can join in! The event will be held August 10-11, 2012, in Hamilton, ON, Canada. This is the third year for this event, last year's battle topped 250,000 points, a number that we aim to crush this year. Anyone wishing to join in should register on the Apocalypticon website, all that you need to have is a 3000 point force - there is no maximum force size. So join in the fun and wade through a sea of titans and super-heavies on your way to greatness!
