Greed Is Good: Isaac Afterbirth’s New Mode Revealed

I had expected this week would bring a trailer announcing a release date for the Binding of Isaac: Rebirth [official site] expansion Afterbirth but no, sadly not.

Instead, co-creator Edmund McMillen has finally revealed the mysterious new mode he’s been teasing. Named Greed Mode, it’s a mob/boss rush-ish survival challenge mode which relies heavily on shops to give lots of options in how you build your baby.

Each floor in Greed Mode will contain one of Afterbirth’s new double-size shops, two treasure rooms, a curse room, a devil room, and a large room with an ominous button in the center. Press the button and monsters will start spawning, while a timer counts down. When it hits 0, in come more monsters. Each waves brings the reward of pennies. You can stop the spawning whenever you want by pressing the button again, but it’ll hurt you and reset your earnings bonus.

Greed Mode relies heavily on shops, see, having them sell a wide selection of items – including boss items – and pickups. You’ll need them for health and keys to open each floor’s second treasure room, as well as simply for upgrades.

There’s a lot he doesn’t explain about the mode, mind, like how waves and bosses and devil rooms and item pools and whatnot work. Well, it wouldn’t be Isaac if you knew what you were getting into.

Regarding the release announcement delay, McMillen says “I know it feels like I’m really fucking with all of you at this point but trust me when I say that this week’s delay was simply due to the inability to nail down the specific release date on Steam and since we are still actively working on getting that in stone.”

    This looks pretty interesting and it will certainly shake things up. The amount of stuff that is going to be added in this expansion is huge, I can’t wait for the release.

    The BoI games and expansions are the only ones that I pre-order. I know it is evil, but until now Edmund delivered and I haven’t been disappointed yet.

    But since there is no release date yet (people suspect it to be the same as the OST, so mid october), I still have time to get platinum god before the release.

      I’m a big fan of BoI, but I can’t help but feel burned by the 3DS release. Upon release it was extremely buggy, music would stop playing, textures wouldn’t load, etc.

      They patched it and now the game randomly freezes the entire device. Two months in and I’ve yet to play the game without having a problem.

        I’m still waiting for an outside-US release… But I suppose the bugs should be fixed first.

    • Jalan says:

      Matthias mentioned on Twitter that he arbitrarily picked a day in October for the Afterbirth OST release date (pushed back from the date he’d originally had it at), so basing the date for the expansion off that isn’t a guaranteed thing.

    BUT I’M OVER MY ADDICTION! Why must you do this to me! I’m actually completing games again, and soon this is going to come along and put an end to all that…
