It's a One Page Rules update, so there's going to be a ton involved. For starters, there's two new games from them. Arena for both Grimdark Future and Age of Fantasy. But they've also got a painting competition going on as well as some more models, and more.
From the article:
This week we’re super excited to release 2 more brand new games, and we have a couple announcements like our October painting competition, 3D models with pre-supports, an FTL fleet builder, and more.
Let’s get to it!
