Greed mode is a game mode introduced in The Binding of Isaac: Afterbirth.

Gameplay[edit | edit source]

Greed Mode Layout.png

In Greed mode, each floor has a Curse Room, a Devil Room/Angel Room, a double-wide Shop, and an exit room all connected to a main double-height arena room with a button in the center. A Super Secret Room is also connected to one of the rooms. Up until the penultimate floor, an already unlocked Treasure Room with a silver door frame and a normal locked Treasure Room are also available. The silver Treasure Room always gives items from the Boss pool. The sixth floor (The Shop) does not have any Treasure Rooms but does have the Shop and Curse Rooms. The final seventh floor has no waves and contains only three rooms, the largest of which contains the game mode's final boss.

When playing Greed Mode, a yellow coin (Greed mode only) will appear on the HUD, below the consumables.

Shop[edit | edit source]

As there are no normal drops in Greed mode, the Shop becomes Isaac's primary source of items and pickups. Shops in Greed mode automatically restock. Shops will always have six items/pickups for sale; in order from the left side of the room to the right, these will always be:

There will also always be two shopkeepers near the center of the room.

Layouts[edit | edit source]

The following room maps were made using Basement Renovator for cleaner viewing.

There is an overall 71.42% chance (15/21) that a shop will have a restock box.

Arena[edit | edit source]

The 1x2 room in the center of all floors except the final one is the Arena, where most of the game mode’s coins and enemies come from. These rooms always have a button in the center that, when pressed, bars all the doors and starts spawning waves of enemies and coins. While active, the button has a timer underneath it that counts down; when the timer runs out or all enemies in the current wave are killed, the next wave spawns. This continues until wave 8 or 10 is reached, Isaac dies, or Isaac presses the button again. Pressing the button before all the waves have spawned deals half a heart of damage to Isaac (or removes 1 penny from the next wave if playing as The Lost) and stops the timer that causes waves to spawn automatically. Once the timer stops and all remaining enemies are killed, the doors re-open. The button can then be reactivated to continue progressing through the waves. All waves except the optional “nightmare” wave must be completed for the door to the next floor to open.

For the first 8 waves, the timer will start at a set time and then increase by 1 second for subsequent waves. For Basement and Caves, the clock starts at 6 seconds. For Depths, the clock starts at 5 seconds. For Womb, the clock starts at 4 seconds. For Sheol and The Shop, the clock starts back at 6 seconds again. The first boss wave is set at 30 seconds on all floors.

The enemies spawned by each wave is determined by the wave number and current floor. For the initial set of eight waves, the first three waves will use the floor’s “easy” enemy pool, the three waves after that use the floor’s “medium” enemy pool, and the last two waves use the floor’s “hard” enemy pool. For the ending two waves, the first wave uses the floor’s “easy boss” pool, and the second wave uses the floor’s “medium boss” pool. Upon completing the second boss wave of the floor, an optional nightmare boss wave, which uses the floor’s “hard boss” pool, can be started by pushing the button again. Clearing the wave grants access to the floor’s Devil/Angel Room. Note that “boss” pools can include multiple (mini)bosses spread out across the room.

Added in Repentance Enemies can spawn as Champions as normal, but will not drop items.

At the start of each wave (except the nightmare boss wave), Pennies are dropped on the ground, which Isaac can use in the Shop to purchase items and pickups. Waves 1-3, 5, 6, and 8 drop 2 pennies, waves 4 and 7 drop 3 pennies, the first boss wave drops 4 pennies, and the second boss wave drops 5 pennies. The mob waves give a total of 18 coins and the boss waves give a total of 9 coins, for a floor total of 27 coins.

Each new wave counts as a new 'room' for purposes of item charges, familiars dropping items or the like. However, one-room temporary effects, such as 15►The Book of Belial The Book of Belial, will remain across waves, and items that activate upon entering a new room will not activate when a new wave starts.

Floors[edit | edit source]

Greed mode has seven total floors, five of which are based on floors found in the main game. These floors are The Basement The Basement, The Caves The Caves, The Depths The Depths, The Womb The Womb, Sheol Sheol, a unique floor called The Shop, and the final boss floor. Each floor will spawn enemies and bosses native to that floor in the main game, except for The Shop, which has no counterpart outside of Greed mode. Instead, The Shop spawns mostly Greed enemies, but can also spawn enemies from any floor. The Shop is the only normal floor which does not contain Treasure Rooms.

Added in Repentance Greed mode floors can appear as their variants with unique waves including Burning Basement Burning Basement, The Cellar The Cellar, Flooded Caves Flooded Caves, The Catacombs The Catacombs, Dank Depths Dank Depths, Necropolis Necropolis, Utero Utero, and Scarred Womb Scarred Womb.

Ultra Greed[edit | edit source]

The Ultra Greed floor contains only three rooms: An empty starting room, a Mini-Boss Room in which multiple Greeds, Super Greed, Wrath or Monstro will spawn, and the final Boss Room containing Ultra Greed. After Ultra Greed has been defeated, turning him into a golden statue, a Final Boss Chest to end the level and the Greed Donation Machine will spawn. Isaac is given the chance to donate his remaining money to the Greed Machine, which will unlock several rewards including the Keeper character.

Greedier Mode Added in Afterbirth †[edit | edit source]

Greedier mode is a harder version of Greed mode. When playing Greedier mode, a small, red stained coin (Greedier mode only) will appear on the HUD, below the consumables.

Greedier mode changes gameplay in the following ways:

  • An additional “hard” wave is added to the initial set of 8 waves, bringing it up to 9.
  • The time the clock starts at is shorter (with the exception for Basement and Caves' mob waves).
    • For The Basement, the clock starts at 8 seconds. For The Caves, the clock starts at 6 seconds. For The Depths, the clock starts at 4 seconds. For The Womb, the clock starts at 3 seconds. For Sheol and The Shop, the clock starts at 2 seconds. The first boss wave is set at 14 seconds on all floors.
  • Coin drops per wave are modified to give less coins overall.
    • Waves 1-3, 5, 6, and 8 drop 1 penny.
    • Waves 4, 7, and 9 drop 2 pennies. (total 12 coins from mob waves)
    • The first boss wave drops 4 pennies.
    • The second boss wave drops 6 pennies. (total 10 coins from boss waves, or 22 for the floor)
    • The nightmare boss wave still drops no coins.
  • Basic enemies have a chance to be champions. They will not drop pickups, unlike the regular game.
  • The final boss gains a second phase.
  • The Greed Donation Machine's chance to jam is greatly reduced, making it much easier to fill out.

Greedier mode unlockables are separate from Greed mode unlockables; however, as of Booster Pack #5, completing Greedier Mode with a character will unlock the corresponding Greed mode unlockable.

Added in Afterbirth †Greedier! Donate 500 coins to the Greed Donation Machine to unlock it.

Tips[edit | edit source]

  • Completing all waves without pressing the stop button will maximize the total possible amount of coins.
  • Flight will not prevent damage from the spiked stop button unless the player is The Lost or the Tainted Forgotten
    • However, a Penny is deducted from the next round of rewards if the button is pressed as The Lost.
  • Items with effects that only persist in the room are especially useful in Greed mode. Complete all waves in one go to maximize their efficiency. Examples of such items include 15►Box of Friends Box of Friends, 15►The Book of Belial The Book of Belial, 15►Lusty Blood Lusty Blood, 15►The Pinking Shears The Pinking Shears, and 15►Scissors Scissors.
  • Being teleported by the Curse of the Maze can open the exit door without needing to complete the floor, allowing large portions of a run to be skipped.
  • Only a half heart of damage is taken in floors beyond chapter 3, a feature unique to Greed mode.
  • Killing all the enemies before the timer resets doesn't increase the number of coins produced.
  • The dead shop keepers have a very low chance of dropping 15►Steam Sale Steam Sale when bombed.
  • There are methods of achieving infinite coins/items. Although difficult to coordinate, and sometimes heavily reliant on luck, these methods can practically guarantee a successful run. These strategies can be combined with 15►Chaos Chaos to allow stronger items to be obtained more easily.
    • Method #1: Requires a 2 of Diamonds card, the 15►Blank Card Blank Card, a Shop selling Lil' Batteries, and enough coins to buy one. This allows infinite coin count doubling with no drawback.
    • Method #2: Requires a Jera rune, the 15►Blank Card Blank Card, a Shop selling Lil' Batteries, and enough coins to buy one. Similar to the first method, but instead of doubling Isaac's currently held coins, this method allows for infinite duplication of Pennies dropped during waves.
      • Added in RepentanceBlank card with runes no longer copies the abillity of the runes
    • Method #3: Use 15►Diplopia Diplopia or the Added in Afterbirth †15►Crooked Penny Crooked Penny on a 15►Steam Sale Steam Sale. This will allow Isaac to take as many items as desired for free.
  • The 15►D20 D20 can be used in tandem with Lil' Batteries to re-roll all Pennies dropped during combat, some of which will become Grab Bags or chests. The process can then be repeated indefinitely.
    • As the D20 re-rolls all opened chests into pickups, chests should not be opened unless the D20 is fully charged.
      • Added in Repentance Opened chests now no longer reroll into more pickups.
    • Using the D20 in conjunction with the Added in Repentance15►Book of Virtues Book of Virtues will destroy all pickups in the room; as such, the D20 should not be picked up while playing as Bethany.
  • In Greedier mode, upon defeating Ultra Greedier, all poops, whether destroyed, damaged or intact, will be converted into golden poops.
    • As a result, A Card Against Humanity can be used to guarantee a large source of coins for the Greed Donation Machine.
  • Common display resolutions, such as 1920x1080 with aspect ratio 16:9, will show only part of the arena in fullscreen mode. Switching to windowed mode and then resizing the window makes it possible to keep an eye on the entire arena while playing.

Helpful Items[edit | edit source]

  • As mentioned above, all items that grant a temporary buff or benefit that expire once Isaac leaves the room are extremely powerful in Greed mode, as these effects can last an entire floor's worth of waves, and some can be stacked.
  • 15►Betrayal Betrayal: Charms every enemy when hit, allowing an entire wave to be cleared at the cost of one hit.
  • Added in Afterbirth †15►Book of the Dead Book of the Dead: Spawns bone orbitals or charmed Bonies when there are killed enemies in a room. Making this item especially useful after the first 8 rounds and before the boss rounds.
  • 15►Dad's Key Dad's Key: Essentially allows Isaac to enter the Treasure and Secret Rooms for free.
  • Added in Afterbirth †15►Dad's Ring Dad's Ring: Petrifies enemies that are close to Isaac and stops enemies from surrounding Isaac with no reprieve.
  • Added in Afterbirth †15►Jaw Bone Jaw Bone: Familiar that will retrieve pickups for Isaac.
  • 15►Red Candle Red Candle: Filling the room with flames before pushing the button will quickly kill all enemies and bosses.
  • 15►Wooden Nickel Wooden Nickel: Allows Isaac to easily gain a lot more money very quickly, as it can be used once per wave.

Trivia[edit | edit source]

  • Ultra Greed’s theme, named “Chorus Mortus”, is a remix of the main menu theme.
  • During Greedier mode beating Ultra Greedier with poop in the room turns it into golden poop.

Bugs[edit | edit source]

Bug Bug! If the Super Secret Room is generated behind the locked (golden) Treasure Room, it is possible to get stuck by teleporting into before unlocking the Treasure Room. The Treasure Room doors all become unlocked when one of them is, unlike the normal game mode where a Treasure Room may have only one locked door, which results in the bombable wall between the Super Secret Room and the Treasure Room also being "locked". It cannot be bombed or opened with a key from inside the Super Secret Room, and unless another means of teleporting is available, the run is softlocked.
