AntibirthFive years ago, a young boy took his first trip down into the basement, facing the endless threats below to escape from the murderous delusions of his loving mother. Three years later, he found himself facing the same predicament but with an even greater plague of horrors and peril. Very shortly afterward, a modest few among us decided that even this was not enough. In the two years since then, fate has worked tirelessly to place by far the most fearsome challenge yet in his path. This time, Isaac will face our free and fan-made expansion, Antibirth.
Questions & AnswersIs this free?Yes!How can I donate? Donate with PayPalWill there be updates?Definitely! In fact, there are still so many significant updates planned that we would consider this to be an Early Access release, so please stay tuned!Is this official?No, we are not affiliated with Edmund McMillen or Nicalis in any way.
We're just really really dedicated fans!Is this compatible with Linux/OSX?Unfortunately no, due to the way the mod works. We are looking into Wine compatibility, but in the meantime we would suggest playing it on a virtual machine.Will there be support for consoles?That is extremely unlikely, again due to the way the mod works.Is this mod compatible with Afterbirth/Afterbirth+?No, this is a Rebirth only mod. However it can co-exist with Afterbirth and you can easily switch between both at any time. We are also planning to add support for all DLCs within the next few months.Will this mod affect my Afterbirth progress?Antibirth uses your Rebirth savefiles, which are completely independent from Afterbirth. It will never have any impact on your Afterbirth savefile. Good advice is hard to come by these days.
Who has time in all the hustle and bustle of fleeing aggressive piles of rotting flesh or dodging the onslaught of floating severed heads to stop at the local fortune teller’s? For the most sagacious wisdom, tarot cards, runes, or even soulful healing on the go, a bucket full of fortune cookies is the busy sacrificial offering’s first and only option. Of course, some scoff at mystic insights, but sooner or later we have to realize that there’s always another secret to uncover. Cooperative spelunkers using the same computer can now control two complete, independent characters with their own separate items, actives, upgrades, trinkets, and consumables! Two twin Isaacs can enjoy twice the D6 rerolling, Samson can seize all the red, eternal, and rotten hearts while Eve helps herself to the soul, black, and immortal hearts, or Azazel could plow through everything while The Lost just tries not to get killed.Isaac and a friend can now embark on the full treacherous experience at once and even unlock things in half the time, or maybe twice the time if they’re not so great at teamwork, but at least they’re free to test the limits of their friendship while the monsters test their mettle. In Isaac’s experience, the worst thing about hurtling downward through the layers of earth and beyond into a series of nightmarish, if metaphorical, hellscapes is arguably that so many of the residents don’t even want him to be there.
Worse yet, they never express it very peacefully. At times like those, Isaac needs more than anything to maintain a strong constitution and be ready to adapt, and nothing does those jobs better than hearts and trinkets, so we think there’s always room for a few more. The Reap CreepFor example, this is the Reap Creep — a hideous amalgamation of the three types of dreadful little spiders you’re used to seeing scurry along the walls and spit at Isaac from afar. As its mood sours throughout the fight, it will switch tactics as its switches faces, if it’s not too perverse to call them that.
With a bounty of assaults including spitting blood, spread shots of tears, summoning its offspring, or even bashing into the walls to see what gets knocked loose, Isaac will wish he had eight legs to help him stay out of harm’s way, or at least a few extra eyes to cry with.
