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

Gameplay[ | ]

Greed Mode Layout

In Greed mode, each floor has a Curse RoomCurse Room, a Devil RoomDevil Room/Angel RoomAngel 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 RoomSuper Secret Room is also connected to one of the rooms. Up until the penultimate floor, an already unlocked Treasure RoomTreasure 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[ | ]

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, sometimes discounted; in order from the left side of the room to the right, these will always be:

There will also almost always be two ShopkeeperShopkeepers near the center of the room, as sometimes just one special shopkeeper spawns instead.

Layouts[ | ]

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[ | ]

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 Character The Lost iconThe Lost or Character Tainted Lost iconTainted 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 BasementBasement and CavesCaves, the clock starts at 6 seconds. For DepthsDepths, the clock starts at 5 seconds. For WombWomb, the clock starts at 4 seconds. For SheolSheol and The ShopThe Shop, the clock starts back at 6 seconds again. The first boss wave is set at 33 seconds (30 after Everything is Terrible 2!!! Everything is Terrible 2!!! is unlocked) on all floors.

The enemies spawned by each wave are 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 RoomDevil Room/Angel RoomAngel Room. Note that “boss” pools can include multiple (mini)bosses spread out across the room.

(in Repentance) Enemies can spawn as Champions as normal, but will not drop pickups, with the exception of Boss The Hollow ingameThe Hollow's gold champion, which drops coins as normal. Rainbow champions drop consumables too, albeit only appear in Sheol in Greed and greedier modes only Greedier version of the mode.

At the start of each wave, Pennies are dropped on the ground, which Isaac can use in the Shop to purchase items and pickups. Each normal wave drops 2 pennies, each boss wave drops 4 pennies and you get a bonus coin after passing through 3 waves without getting hit in your red hearts. That means on a full hitless floor, you'll get an extra coin on waves 4, 7 and 10, bringing the total of coins earned to 27 per floor. This extra coin mechanic explains why sometimes you can get a coin on the "nightmare" wave: if you get hit in the red hearts on the 7th wave but don't get hit on the 8th, 9th and 10th waves, you'll get the extra coin on the 11th.

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 Collectible The Book of Belial iconThe Book of Belial, will remain across waves, and items that activate upon entering a new room will not activate when a new wave starts.

  • (in Repentance)Collectible Taurus iconTaurus is an exception and will activate each time the button is pressed to start a wave.

Floors[ | ]

Greed mode has seven total floors, five of which are based on floors found in the main game. These floors are BasementBasement, CavesCaves, DepthsDepths, WombWomb, SheolSheol, a unique floor called The ShopThe 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.

(in Repentance) Greed mode floors can appear as their variants with unique waves including Burning BasementBurning Basement, CellarCellar, Flooded CavesFlooded Caves, CatacombsCatacombs, Dank DepthsDank Depths, NecropolisNecropolis, UteroUtero, and Scarred WombScarred Womb.

Ultra Greed[ | ]

The Ultra Greed floor contains only three rooms: An empty starting room, a Mini-Boss Room in which multiple GreedGreeds, Super GreedSuper Greed, WrathWrath or Boss Monstro ingameMonstro will spawn, and the final Boss Room containing Boss Ultra Greed ingameUltra 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 MachineGreed 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 Character Keeper iconKeeper character.

(in Afterbirth † and Repentance) Greedier Mode[ | ]

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.

You must Greedier! Donate 500 Coins to the Greed Donation MachineGreed Donation Machine to unlock it.

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 BasementBasement, the clock starts at 8 seconds. For CavesCaves, the clock starts at 6 seconds. For DepthsDepths, the clock starts at 4 seconds. For WombWomb, the clock starts at 3 seconds. For SheolSheol and The ShopThe 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 fewer coins overall.
    • Waves 1-8 drop 1 penny.
    • Wave 9 drops 2 pennies. (total 10 coins from mob waves)
    • The first boss wave drops 3 pennies.
    • The second boss wave drops 6 pennies. (total 9 coins from boss waves)
    • Plus the extra coin mechanic explained above that can give 3 additional coins, bringing the potential total to 22.
  • 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 were separate from Greed mode unlockables; however, as of Booster Pack #5, completing Greedier Mode with a character will also unlock the corresponding Greed mode unlockable.

Despite being a "hard" version of Greed, most hard mode rules from the vanilla gamemode don't apply.

Tips[ | ]

  • Flight will not prevent damage from the spiked stop button unless the player is Character The Lost iconThe Lost, Character Tainted Lost iconTainted Lost, or Character Tainted Forgotten iconTainted Forgotten.
    • However, a Penny is deducted from the next round of rewards if the button is pressed as Character The Lost iconThe Lost or Character Tainted Lost iconTainted Lost. It is possible to negate this by triggering the button and surviving until all waves have spawned before quitting out. When you reload the save, all of the coins will be on the ground. Pressing the button again will start the waves from wave 1. You can now press the button to cancel waves with no loss of coins.
  • 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 Collectible Box of Friends iconBox of Friends, Collectible The Book of Belial iconThe Book of Belial, Collectible Lusty Blood iconLusty Blood, Collectible The Pinking Shears iconThe Pinking Shears, Collectible Scissors iconScissors, and (in Repentance)Collectible Sulfur iconSulfur.
  • 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.
    • This makes items such as Collectible The Wafer iconThe Wafer substantially less useful, since there is a limited number of enemies that could cause more than a half heart of damage. However, they can still be used for the Ultra Greed boss fight, since all of his attacks deal a full heart of damage.
  • Killing all the enemies before the timer resets doesn't increase the number of coins produced.
  • It is highly advised to destroy polyps, mushrooms, fires, and sometimes even ordinary rocks before starting a wave, as they might cause you to take unavoidable damage.
  • It is also often a good idea to get rid of pickups on the ground if possible, as they could be handicapping your ability to aim or dodge in a relatively cramped arena.
  • Due to the fact that the mode lacks a presence of rocks, finding crawlspaces is way easier.
  • Using keys or bombs to open golden and stone chests is almost always worth it since it's highly likely that it will return your bomb, key, or other pickups; it could even give you something like Collectible A Quarter iconA Quarter.
  • Trying to stay somewhere in the middle of the room is pretty smart as it allows you to see most of the arena from the bird's eye view, as well as avoiding potential instant damage.
  • It is often a good idea to press a button when the arena is flooded by invulnerable entities like floating heads or spike blocks, so that they are guaranteed to die once everything is over. Pressing the button isn't necessary since these types of enemies cease to exist after a wave clear anyways, however it is a good idea to do so if you get surrounded.
  • Firing non-stop is not always the wisest thing to do as it can lead to instant damage, from something like explosions for example. Items like Collectible Cursed Eye iconCursed Eye and Collectible Chocolate Milk iconChocolate Milk help avoiding that, although Cursed Eye is still a double edged sword.
  • If it feels like a boss' Healthbar lasts too long it might be a good indicator that there's another boss spawned alongside the one you can see, just hiding in the ground.
  • Buying Collectible A Lump of Coal iconA Lump of Coal might not always be the best idea, especially with Devil's precedent locked in — since it has good odds to reappear from Krampus. This happens even if you've taken the item already, let alone just encountering it without buying.
  • "The Shop" penultimate chapter often spawns several shopkeeper entities throughout the waves, which can be blown up for extra cash.
  • The dead shop keepers have a very low chance of dropping Collectible Steam Sale iconSteam Sale | Counterfeit PennyCounterfeit Penny and other useful outcomes when bombed.
  • Sometimes spending the acquired pennies may be wiser on the next floor. Certain collectible items, hearts or keys may be on sale a depth below, which saves money compared to refilling them when not yet necessary.
  • Any form of homing is tremendous in this gamemode as its' effect covers a relatively large part of the arena.
  • (in Repentance) "Ace of" cards are very helpful to use on spawning enemies — be it to heal up or gain resources.
  • Collectible Sack Head iconSack Head tends to replace the coins (in Afterbirth † and Repentance) Boss Ultra Greedier ingameUltra Greedier's coin explosions spawn, which can be useful for Character Tainted Lost iconTainted Lost with a clutch (in Afterbirth † and Repentance)Holy CardHoly Card. Alternatively - it could be useful for battery drops instead.
  • 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 Collectible Chaos iconChaos to allow stronger items to be obtained more easily.
    • Method #1: Requires a 2 of Diamonds2 of Diamonds card, the Collectible Blank Card iconBlank Card, a Shop selling Lil' BatteryLil' Batteries, and enough coins to buy one. This allows infinite coin count doubling with no drawback.
    • Method #2: Requires a Rune of JeraRune of Jera, the Collectible Blank Card iconBlank Card, a Shop selling Lil' BatteryLil' 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.
    • Method #3: Use Collectible Diplopia iconDiplopia or the (in Afterbirth † and Repentance)Collectible Crooked Penny iconCrooked Penny on a Collectible Steam Sale iconSteam Sale. This will allow Isaac to take as many items as desired for free.
      • (in Repentance) This method is no longer infinite, as stacking multiple Collectible Steam Sale iconSteam Sale uses a new algorithm.
    • Method #4: Requires Swallowed PennySwallowed Penny and a discounted red heart (2c). Use the curse door by entering and exiting right after losing only half a red heart and spawning a coin. By repeating the process long enough you can get infinite coins, Swallowed PennySwallowed Penny being able to spawn nickels and dimes and being guaranteed 1 penny per half heart. If Collectible Mom's Box iconMom's Box is held, this method can be performed without a discounted red heart as the number of coins spawned by Swallowed PennySwallowed Penny will be doubled.
  • The Collectible D20 iconD20 can be used in tandem with Lil' BatteryLil' 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.
    • (except in Repentance) As the D20 re-rolls all opened chests into pickups, chests should not be opened unless the D20 is fully charged.
    • (in Repentance) Using the D20 in conjunction with the Collectible Book of Virtues iconBook of Virtues will destroy all pickups in the room; as such, the D20 should not be picked up while playing as Character Bethany iconBethany.
  • (except in Repentance) In Greedier mode, upon defeating Ultra Greedier, all poops, whether destroyed, damaged or intact, will be converted into Golden PoopGolden Poops.
    • As a result, A Card Against HumanityA Card Against Humanity can be used to guarantee a large source of coins for the Greed Donation Machine.
      • (in Repentance) Poops spawned inside of the Ultra Greedier fight are turned into yellow colored poops, and drop normal brown poop pickups.
  • 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[ | ]

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.

  • Collectible Cube of Meat iconCube of Meat & Collectible Ball of Bandages iconBall of Bandages,Collectible Mom's Heels iconMom's Heels,Collectible The Virus iconThe Virus,Collectible Serpent's Kiss iconSerpent's Kiss and Collectible My Shadow iconMy Shadow: Since the mode prevents telefragging for a tiny amount of time even if enemies spawn on top of you - the contact damage trait of that item becomes very useful to instantly kill those that spawn on you with no consequences, however it can turn out badly if said monsters are explosive.
  • (in Repentance)Collectible Keeper's Kin iconKeeper's Kin: Provides support in early floors due to the abundance of rocks.
  • Collectible Glass Cannon iconGlass Cannon: helps immensely with clearing waves, it's possible to even use it in advance before pressing the buttons to get use of 2 shots in a row.

    • While playing as Character Tainted Judas iconTainted Judas, each enemy or projectile ran into will grant a damage buff. With the sheer amount of enemies appearing, especially in Greedier, Tainted Judas will gain an immense damage buff and can kill huge swaths of enemies with ease. Additionally, this is even more potent against Boss Ultra Greed ingameUltra Greed, as you can run through the many Greed GaperGreed Gapers summoned to gain even greater damage buff, as the Gapers will be clustered very closely together.
  • (in Repentance)Collectible Gello iconGello: Incredibly powerful, as it can be activated multiple times in the same room.

  • Counterfeit PennyCounterfeit Penny, Swallowed PennySwallowed Penny and all other penny trinkets are useful due to the nature of Greed Mode.

  • (in Repentance)Sigil of BaphometSigil of Baphomet: The wave based enemy spawns allow for constant uptime.
  • (in Afterbirth † and Repentance)Collectible Coupon iconCoupon: Can be used to make pickups or items free in the shop, in exchange for making them no longer restock.

Unhelpful Items[ | ]

  • (in Afterbirth † and Repentance)Collectible Blanket iconBlanket: Only grants a shield for the two boss fights on the final level. The shield does not activate for the regular boss waves on previous floors.
  • (in Afterbirth †)Collectible Camo Undies iconCamo Undies: This item does almost nothing in Greed Mode, despite being able to be obtained from the Greed Mode Treasure Room.
    • (in Repentance) Due to its ability to destroy ShopkeeperShopkeepers, Camo Undies can net you some extra pennies or nickels from shops each floor. Its new effect in Repentance also nets you a risk-reward dynamic as long as you re-enter the arena. You risk by losing money but get rewarded by clearing the waves easier.
  • Collectible Champion Belt iconChampion Belt:While it does provide a damage up, it also quadruples the chance for champion enemies to appear, while not being able to profit from any extra pickups dropping from champions.
  • Collectible D12 iconD12: Very few rocks to reroll, however, can be abused to force a hatch to the next floor.
  • (in Afterbirth † and Repentance)Collectible Eucharist iconEucharist: You're already guaranteed an Angel or Devil deal each floor, so all this does is ensures that it's an Angel Deal.
  • (in Repentance)Collectible Guppy's Eye iconGuppy's Eye: This item is substantially less useful in Greed Mode, due to the scarcity of chests.
  • Collectible Guppy's Tail iconGuppy's Tail: This item has no effect in Greed Mode other than counting towards the Guppy Transformation.
  • Collectible Holy Mantle iconHoly Mantle: Only triggers once without leaving the room, however can still be useful to make use of curse rooms for free; As well as deactivating the wave button with no consequences.
  • Collectible Monstro's Tooth iconMonstro's Tooth: Only targets one enemy, virtually useless with the exception of cleaning up dead shopkeeper bodies.
  • (in Repentance)Collectible Mom's Bracelet iconMom's Bracelet: Very few rocks to throw.
  • (in Afterbirth † and Repentance)Collectible Mama Mega! iconMama Mega!: The explosion will only trigger once per room, making it effectively useless in Greed Mode after the first activation.
  • Collectible The Mind iconThe Mind: In Greed Mode, this item effectively becomes Collectible Blue Map iconBlue Map. Other map-related items such as Collectible Treasure Map iconTreasure Map and Collectible The Compass iconThe Compass are negated completely irrelevant.
  • (in Afterbirth † and Repentance)Collectible Pause iconPause: Using the item in Greed Mode will freeze all enemies but will not pause the timer. New waves of enemies will continue to spawn even while the effect is active.
  • (in Repentance)Soul of CainSoul of Cain: Will show red door outlines, but cannot generate normal red rooms, leaving only special rooms as a rare possibility. The red outlines can be used to find the Secret Room or leave the floor, however.
  • (in Repentance)Collectible Meat Cleaver iconMeat Cleaver: Virtually useless, especially considering how pretty much none of the champions drop any pickups.
  • (in Repentance)Collectible Dream Catcher iconDream Catcher Doesn't show the outcomes for the boss waves and is bugged in the way that it doesn't show the right items, making it useless outside of the half-soul heart it gives each floor.
  • (in Repentance)Collectible Deep Pockets iconDeep Pockets: Doesn't actually increase the amount of money you gain, causing it to only be valuable if you had a way to generate absurd amounts of money, which you don't need Deep Pockets to do.

Trivia[ | ]

  • Ultra Greed’s theme, named “Chorus Mortis”, is a remix of the main menu theme.
  • Greed Mode is the only place in the game where Collectible Match Book iconMatch Book doesn't drop Match StickMatch Stick.
  • Despite being possible to make, red rooms will only open if a generated one is a special one, or if you're on the final floor. Red Rooms on the last floor are mostly empty with no contents inside. Some red rooms on the final floor can be curse rooms or super secret rooms with some pickups in them.
  • Unlike normal mode, deal chances will only appear after doing the extra wave.
  • (in Afterbirth † and Repentance)Collectible Sulfuric Acid iconSulfuric Acid is both a blessing and a curse since it helps to always find secret rooms for free and destroy polyps to avoid damage that out of your hands; however it is bad for Character The Lost iconThe Lost and Character Tainted Lost iconTainted Lost because you effectively can't hide inside rocks anymore.
  • Both Collectible Head of the Keeper iconHead of the Keeper and (in Afterbirth † and Repentance)Collectible Eye of Greed iconEye of Greed are very useful throughout the entire run but harm you severely during the final boss fight by giving Boss Ultra Greed ingameUltra Greed and (in Afterbirth † and Repentance) Boss Ultra Greedier ingameUltra Greedier a consistent way to heal themselves.
  • Collectible Money = Power iconMoney = Power is a double edged sword in the mode as it essentially forces you to choose between buying shop items, or saving them for damage and the Greed Donation Machine.
  • Doodles that pop-up at the start of a run are always greed-themed in this gamemode.
  • The combat room before Ultra Greed boss fight doesn't grant active item charges.
  • Isaac doesn't have the animation of jumping inside a golden chest in the end, possibly drawing a parallel with the ending in which he gets stuck inside a cave, drying up and becoming Greed.

Bugs[ | ]

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.
Bug Bug! Using (in Repentance)Collectible Genesis iconGenesis forces you down a new "Ultra Greed" floor instead of the safe place, even if the final boss is already killed.
Bug Bug! (in Repentance)Collectible Dream Catcher iconDream Catcher shows the wrong items in Greed mode.
