This article is about the Afterbirth † content updates. For the passive item, see Booster Pack (Item). Booster Packs were recurring content updates for The Binding of Isaac: Afterbirth †. Booster Packs contained popular community-developed mods as updates in the game continued to add features.

• Booster Pack 3 is the only booster pack to not be featured on a blog post.
• The developers of Antibirth helped create booster packs 4 and 5.
• Many of the added Co-op Babies from Booster Pack 5 are references to popular mods that were never added in the Booster Packs.
