The Binding of Isaac: Afterbirth+ goes live on Steam today

Today's announcement that The Binding of Isaac: Afterbirth+ is live in November. Mod makers don't have to submit their work for consideration—"You can honestly do whatever the hell you wanna do," McMillen wrote—but for the benefit of those who do, he also provided a list of basic guidelines for the content he's looking for, including theme and design tips, ideas about enemies, bosses, and challenges.

Getting your work to him will be a bit of a crapshoot at first: He suggested tweeting a gif or video of your mod in action (but don't overdo it), or maybe posting something on Reddit. "It's a bit hamfisted," he admitted, "but as the months roll by I'm sure we will find a smooth way to exchange ideas and I'll keep updating the blog with new info as the year unfolds." 

The Afterbirth+ announcement post also warned that "like any launch there is a good chance that we missed some bugs and players may experience some issues that our testers might have missed." The developers will continue to work on over the launch week, and there may be some nerfing too, if it proves necessary.
