Binding of Isaac DLC Logo Large

Transform your Binding of Isaac: Afterbirth experience with these special Easter egg seeds. Instead of generating random dungeons, you’ll unlock cheat-like effects that alter tons of gameplay factors. Check out the complete list below.

The Binding of Isaac is all about randomness. Random items, random upgrades, random enemies, random everything; it’s a rogue-like, challenging your weak character to grow into an unstoppable powerhouse by the time they reach the last boss. But, there are ways to lock-in special effects while playing through your latest basement run.

By unlocking then activating Easter eggs, you can give Isaac a giant head, change enemy behavior, turn objects invisible, leave poo trails, or tons of other weird mutators that are a permanently embedded into your randomized dungeon layouts — until you switch the Easter eggs off, that is.

Easter Egg Seeds List

To input a SEED, press [Tab] in the Character Select menu.
