Binding of Isaac: Rebirth is over three times the size of the original

Binding of Isaac: Rebirth, a rebooted version of the 2011 cult indie hit from designer Edmund McMillen, features over three times the amount of levels previously made available in the game's original release, McMillen confirmed on his blog.

In short, Rebirth will be a lot bigger than before. The game will feature over 450 items, which is over double the number of items found in both the original Binding of Isaac and the Wrath of the Lamb expansion. Additionally, Rebirth will include over 50 new enemies, over 15 new bosses, and the introduction of "double trouble" boss fights that force players to fight the two previous chapter bosses at once.

Where the original game featured 150 rooms for each chapter, the updated game has over 500 rooms. These rooms feature a rarity slider, writes McMillen, so certain rooms generate with more rarity than others. The game also includes five new special room types, although McMillen doesn't delve into what they are just yet.

The new version of the game, first revealed in 2012, is being "remade from scratch," the developer said at the time. It will also add co-op play, new challenge runs and other new features, all of which are being programmed by Nicalis, of Cave Story and VVVVVV fame.

Those who already own The Binding of Isaac will receive a "Steam loyalty discount" when buying The Binding of Isaac: Rebirth.
