Added in Afterbirth †

A Victory Lap is a mechanic added in The Binding of Isaac: Afterbirth †. A Victory Lap allows you to start a new run with almost all of your final items after killing The Lamb in the Dark Room Dark Room. Multiple laps can be made as long as the Dark Room is cleared each time.


  • Completion marks and achievements cannot be earned (except for the achievements earned for completing victory laps).
  • Isaac will take a full heart of damage on all floors after beginning a victory lap (unless he has 15►The Wafer The Wafer).
  • The effects of all Pills are re-randomized.
  • Some items are lost upon starting a victory lap. Items lost this way are added back into their respective item pools and can be acquired again.
    • Added in RepentanceThis mechanic can remove items in a character's card/pill slot, which leaves an empty slot that the player can still switch to.
  • All victory laps will be on hard difficulty, even if the initial run wasn't.
  • Once the third victory lap has been reached (and on every subsequent victory lap), several effects occur:
    • Isaac will turn into The Lost The Lost.
      • Removed in Repentance This version of The Lost does not get 15►Holy Mantle Holy Mantle or the Eternal D6 However, if the run was started as The Lost (or if the Holy Mantle was found) it is possible to keep the Holy Mantle from the previous run.
      • Added in Repentance This version of The Lost has Holy Mantle if it has been unlocked by donating to the Greed Machine.
      • Tainted Forgotten Tainted Forgotten instead has both entities become The Lost, controlled with the same inputs like Jacob and Esau Jacob and Esau, removing both the Soul's attack restriction and the ability to pick up and throw the Forgotten. The drop key cannot be held to individually control each character, and items previously acquired are held by the The Forgotten. The Soul can acquire its own items.
    • Shops will no longer appear (except for in ??? ???).
    • Red Chests in the Dark Room Dark Room will turn into Brown Chests and Golden Chests.
  • If a Devil Deal is taken at any point during the entire run, Angel Rooms will no longer appear (unless Added in Repentance15►Act of Contrition Act of Contrition, 15►Duality Duality or 15►Eucharist Eucharist is picked up, or a Sacrifice Room allows Isaac to enter an Angel Room).
  • If the Donation Machine jams, it will remain jammed on all subsequent victory laps.
  • The Donation Machine can be donated to and even jammed, but the amount of coins will not increase.


  • Killing any final boss aside from The Lamb will end the game, and the run will not be continued further.
  • 15►The Negative The Negative may disappear upon starting a victory lap and must be reacquired to access the Dark Room Dark Room and continue the run.
  • Isaac can still change characters after becoming The Lost The Lost on the third lap (e.g., 15►Ankh Ankh, 15►Lazarus' Rags Lazarus' Rags, 15►Clicker Clicker).
    • Added in Repentance Obtaining Added in Repentance15►Genesis Genesis will transform The Lost The Lost back into the character you originally were.
  • Transformations will remain even if the items used to acquire them are removed.
    • Added in RepentanceTransformations won't remain if the items used to acquire them are removed.
  • When using Telepills or other teleportation items in Womb Womb II or equivalent, Isaac may be teleported to the I Am Error room with only a way to the Cathedral Cathedral, possibly ending the victory lap streak.
  • If a Sacrifice Room appears in the Cathedral Cathedral, Isaac may be able to teleport to the Dark Room Dark Room if he has enough health, continuing the run.
  • Entering The Void The Void and killing Delirium will end the victory lap streak.
  • The achievement U Broke It! (unlocked by obtaining 50 items) can be earned with Victory Laps.
    • Added in RepentanceThis achievement can no longer be earned in Victory Laps.
  • 15►Broken Shovel Broken Shovel/15►Broken Shovel Broken Shovel are still obtainable in a victory lap, but using 15►Mom's Shovel Mom's Shovel on the dirt mound in the Dark Room will not unlock The Forgotten The Forgotten during a victory lap.
  • Stats obtained via using Black Rune Black Rune or 15►Void Void will not be removed after starting a new lap.
  • Effects from absorbed trinkets via the effects of Gulp!, 15►Marbles Marbles, or 15►Smelter Smelter will not be removed after starting a new lap.
  • Enemies and bosses killed with Added in Repentance15►Eraser Eraser will remain erased after starting a new lap.

Unlockable achievements[]


  • This mechanic is similar to Nuclear Throne's looping system, where defeating a certain boss loops back to the start of the game with a higher difficulty.
  • According to Edmund McMillen, the Victory Lap mechanic is only included in the Dark Room, since it's the Harder Chapter 6 path, therefore being set as a "reward" there.
