A massive expansion to The Binding of Isaac: Rebirth—the game that made living in your mother’s basement cool—has been in the works for a while. And now with an official release date of October 30th and the opportunity to pre-purchase the game at a discounted price, the release of The Binding of Isaac: Afterbirth feels right around the gruesome corner.

So what can we look forward to? According to the Steam page:

  • Over 100 hours of MORE gameplay
  • Greed Mode – a whole new way to play, focused on risk/reward
  • Expanded main game – a new final area with a new final boss
  • Daily Runs – play a new official run, everyday!
  • Online Leaderboards – compete for highscore/best time
  • 10 totally new and awesome challenges!
  • 1000+ new room designs, as well as room
  • MONSTROUSLY UPDATED WEAPON COMBO SYSTEM!
  • 120 new items–not counting tons of new pickups, chests, pills, bombs and cards–taking the item count up beyond 500!
  • Alternate soundtrack!
  • Tons of new secret transformations!
  • MOAR new achievements
  • Lilith, mother of demons, a totally new playable character
  • 4 new alternate chapters with new enemy types and visual themes
  • Revised seed code combo system and new special seeds
  • 100+ enemies, with new designs
  • 8 new bosses
  • Even more rooms FULL OF POOP!
  • and probably at least 5 other features we can’t remember due to all the crap that we threw into this little monster

And in spite the fact that part of those features are redundant and/or don’t make any sense, there’s still a heaping ton of new stuff to look forward to. And if you nab it before the release, you’ll get the thing for an evil $6.66 USD, which is a full 39% off the regular price.
