Binding of Isaac: Rebirth Wiki

(in Afterbirth † and Repentance)

Plan C is an unlockable activated item added in The Binding of Isaac: Afterbirth †.

Effects[ | ]

  • Upon use, deals 9,999,999 damage to every enemy in the room, then kills Isaac 3 seconds later.

Notes[ | ]

  • Plan C does not kill both or all phases of bosses like Boss The Lamb ingameThe Lamb, Boss Hush ingameHush, Boss Ultra Greed ingameUltra Greed, Mega Satan Head ingameMega Satan, (in Repentance) Boss Mother secondphase ingameMother and (in Repentance) Boss The Beast ingameThe Beast.
  • Some bosses have special interactions with this item:
    • Attempting to use this item to kill Boss Delirium ingameDelirium or (in Repentance) Boss Mother secondphase ingameMother will not work. Their death animation is much longer than the time between using Plan C and Isaac's Last Will appearing, meaning Isaac will die first and it will not count as a kill. Having extra lives that revive Isaac outside the room will not help, either; They must be fought again.
      • However, items that revive Isaac in the same room he died in, namely Collectible Lazarus' Rags iconLazarus' Rags (or being Character Lazarus iconLazarus), (in Repentance)Collectible Inner Child iconInner Child, (in Repentance)Soul of LazarusSoul of Lazarus, and Character Tainted Lost iconTainted Lost's (in Repentance)Collectible Birthright iconBirthright, will allow Isaac to bypass this and kill them with this item. In the case of Lazarus' Rags, though, the completion mark will go toward Lazarus and not the character originally selected.
        • Similarly, if playing as Character Tainted Lazarus iconTainted Lazarus, using Plan C and then using (in Repentance)Collectible Flip iconFlip to switch to the other form pauses the death counter until the player switches back to the form that originally used the item.
      • It is possible to kill Delirium by carefully timing pauses after each screen static. Each screen static plays a cutscene that continues to play even while paused, so by pausing and unpausing at the right timings, Delirium's death animation can be shortened to just under 3 seconds allowing for his completion mark to be awarded.
      • Using the effect of Plan C while Isaac is already under the timer of Plan C (such as trough the use of another Plan C, ? Card? Card, (in Repentance)Wild CardWild Card, ect.) will reset the timer each use, allowing to stall bosses with long death animations.
    • (in Repentance) Killing Boss Mother secondphase ingameMother's second phase with Plan C will kill Isaac just at the end of her death animation. No completion mark is awarded.
    • Greedier mode only Killing Boss Ultra Greed ingameUltra Greed's second phase with Plan C will give a completion mark, with the exception of Character The Lost iconThe Lost, Character Tainted Lost iconTainted Lost, Character The Forgotten iconThe Forgotten (when playing as The Soul), and Character Tainted Forgotten iconTainted Forgotten. This is because ghost characters have a slightly shorter death animation, resulting in Isaac's Last Will appearing more quickly.
    • (in Repentance) If used in Boss The Beast ingameThe Beast battle, Plan C will only kill the harbinger that Isaac is fighting on screen. It won't have any effect on the other harbingers nor The Beast itself (The Beast can still be killed if Isaac is fighting it when Plan C is used, and there is enough time to earn the completion mark).
  • It is recommended not to use this item in Challenges, as even if the goal is within the bosses that dies before Isaac does, the player will likely die before the end of the rising trophy animation.
  • For the game's sake, a run is not truly over until Isaac's Last Will appears. This means that some bosses that might seem to finish their death animations after Isaac dies, such as Ultra Greed, will still be technically killed and will still give their completion marks, even if Isaac does not enter the Final Boss Chest.
  • Invulnerable enemies and closed HostHosts will not be killed by Plan C.
  • Isaac's last will shows his last damage source as the cause of death, not Plan C. If Isaac has not taken damage or lost health from any source, Isaac's face is shown.
  • Invincibility or the Collectible Holy Mantle iconHoly Mantle shield will not save Isaac from being killed.
  • Some items that activate when Isaac reaches zero hearts, such as (in Repentance)Collectible Heartbreak iconHeartbreak and (in Repentance)Collectible Spirit Shackles iconSpirit Shackles, will not activate, killing Isaac.
  • Even if Isaac enters a trapdoor immediately after using Plan C, he will still die after arriving at the next floor.
  • Plan C has an 80% decreased item pool weight, making it less likely to appear than other collectibles.
  • (except in Repentance) Plan C is found in 6 item pools, the second highest count amongst all items, behind Collectible Cube of Meat iconCube of Meat. Its lowered weight, however, offsets its presence.
    • (in Repentance) Plan C is found in 8 item pools, the highest count amongst all items. Its lowered weight, however, offsets its presence.

Trivia[ | ]

  • This item is a reference to abortion pills, which are commonly given the nickname "Plan C." ("Plan A" being typical birth control methods, and "Plan B" being the so-called "morning-after pill," which prevents pregnancy in cases where contraception has failed.) The item's mechanic is a reference to abortion terminating an unborn fetus.
  • Plan C's sprite is a red-tinted Collectible Forget Me Now iconForget Me Now.
  • In Afterbirth+, the pickup quote for the item was "Use with caution."
