The announced today that the game will debut on Steam on January 3 with a full suite of mod tools, new items, trinkets, and pickups, a new final chapter, plus a new final boss, playable character, "greedier" greed mode, and more. 

"So basically what you are looking at is a slightly smaller afterbirth expansion but with mod tools that potentially make it 20 times larger!" McMillen wrote. "I'm honestly quite excited about what the community will end up making and even more excited to make some of it totally official in Isaac!"
