The Binding of Isaac: Afterbirth †/Additions

* 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 on 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 Chests and Locked Chests.
	+ Killing any final boss aside from The Lamb will end the game, and the run will not be continued further.

### Chests

 Mimic Chests
* Mimic Chests 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.

## Entities

## Environment

### Obstacles

 Super special rock
* Super special rocks are tinted rock variants which are much harder to spot, as they have a smaller mark and are not discolored. Super special rocks takes two bombs to blow up, and drop the contents of two tinted rocks.

 White poop
* White poop is surrounded by an aura that halves tear delay and has a high chance to block damage like the  item while Isaac stands within it. The aura disappears if the poop is destroyed.

 Dirt Patch
* Dirt Patches are a small mound of dirt that can be dug into with certain items. Using  on top of a Dirt Patch will reveal a skeleton and unlock The Forgotten. Once The Forgotten is unlocked, using Mom's Shovel, , or  on top of a Dirt Patch will dig up a random chest.

### Machines

 Mom's Dressing Table
* It appears in the starting room of a floor if Isaac has 8 or more items.
* If Isaac bumps into Mom's Dressing Table, his appearance will be randomly changed so that only a few of his items are displayed.
* Hitting Mom's Dressing Table with an explosive will cause it to vanish and drop 1-4 pills. There is a 1% chance to spawn one of the following items instead: Mom's Underwear, Mom's Heels, Mom's Lipstick, Mom's Bra, Mom's Pad, Mom's Eyeshadow, Mom's Contacts, Mom's Wig, Mom's Perfume or Mom's Pearls.
