Eve's Dropping: The Binding Of Isaac

The most common complaint about The Binding of Isaac is that it doesn't contain enough horrid things in it, being a rather delicate cocktail of blood, tears and poo. Thankfully, the Halloween update, which will automatically apply itself to Steam copies of the game by noon PST today, adds "20% more evil". It says so in the trailer, which is gibbering madly in the sulfurous depths below, along with some details on what that extra evil is composed of, including new playable character Eve.

It's such a cheerful and righteous game. Halloween isn't about pumpkins for Edmund McMillen; it's about pacts with the Devil and the abandonment of hope. If the little chaps from Costume Quest went trick or treating around his undoubtedly terrifying edifice of a home, they may be well advised to check for razorblades in the candy.

So, here's what the update contains:

-Added chapter 5 (unlocked after 10 mom kills)
-Added 3+ new bosses
-Added 4 new enemies
-Added 20+ new items
-Added one new unlockable character (Eve)
-Added one new "FINAL" ending.
-Added 6+ new achievements
-Added 2 new music tracks
-Added updated collection viewer
-Added 4 new tarot cards (finishing the major arcana)

That seems a healthy amount of clearly unhealthy content. I must admit that despite being very keen about the game, I'm not particularly good at it so it may take me a while to reach the "FINAL" ending, but new items, enemies and bosses are all more than welcome. Has everybody else who is actually playing performed sufficient amounts of matricide to unlock everything?
