The Binding of Isaac: Afterbirth †/Additions

Mechanics

HUD

Found HUD

• Found HUD is a HUD addition that appears on the left side of the screen that gives numerical values to the player's current stats (e.g., damage, luck, speed, devil room chance). It can be enabled through the options menu.
• It is based off of the Missing HUD mod for Rebirth and Afterbirth.

Victory Lap

• A Victory Lap allows you to start a new run with almost all of your final items after completing the Dark Room. Multiple laps can be made as long as the Dark Room is cleared each time.
  • Completion Marks and most Achievements cannot be earned.
  • Isaac will take a full heart of damage on all floors after beginning a victory lap (unless he has The Wafer).
  • 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.
  • If the initial run was on normal difficulty, all victory laps will be on hard difficulty.
  • On the third and subsequent victory laps, the character will turn into The Lost. This version of The Lost does not get a Holy Mantle or D4. 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.
  • On the third and subsequent victory laps, shops will no longer appear.
  • On the third and subsequent victory laps, red chests in the Dark Room will turn into {{brown chest]]s and golden chests.
  • Killing any final boss aside from The Lamb will end the game, and the run will not be continued further.

Menus

Options

Charge bars

• Added a new "charge bars" option in the menu, for passive items that need to be charged up before usage.

RERUN

Chests

Mimics

• Mimics appear similar to Brown Chests until Isaac moves near, at which point they sprout spikes that damage the player as a Spike Chest would. They can be distinguished from Brown Chests by their darker, purplish-brown coloring, the grayish spot on each side of the latch where the spikes will sprout from and the bloodstain.
