Greed Mode is a new game mode introduced in the Binding of Isaac: Afterbirth expansion.

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. The items for sale are a key, a heart pickup, a shop item, a boss item, and two random pickups, trinkets, or items from the treasure room pool.

The shop has a chance of containing a Restock Box, along with various pickups, machines, and beggars.

Arena[edit | edit source]

When the button is pressed, it turns red, grows spikes, and a timer appears underneath it. All doors are barred and waves of random enemies start spawning. The timer initially starts with 6 seconds left and will be increased by 1 second for every subsequent wave of enemies. Once the timer runs out or all enemies in the current wave are killed, another wave spawns. This continues until wave 8 is reached, Isaac dies, or Isaac presses the red button. Pressing the red button deals half a heart of damage to Isaac and causes waves to stop spawning, and once all remaining enemies are killed, the doors re-open. The button can then be re-activated to continue progressing through the waves. As The Lost, there is a coin penalty for hitting the button before the wave is completed of 1 penny.

At the start of each wave (with the exception of the nightmare boss wave), pennies are dropped on the ground, which Isaac can use in the shop to purchase items and pickups. 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 The Book of Belial The Book of BelialThe Book of Belial Icon.png3 roomsUpon use increases damage by 2 for the current room and by a further +50% if the character also has the Blood of the Martyr.

, will remain across waves.

2 and occasionally 3 pennies will drop for each of the first 8 waves. Upon completing the eighth wave, a skull appears on the button. Pushing the skull button starts the two boss waves, which grants access to the floor's exit room upon completion. A total of 9 coins will drop for these boss waves. Each boss wave will spawn one boss/mini-boss.

Upon completing the tenth wave of the floor, a pentagram appears on the button. Pushing the pentagram button starts the optional nightmare boss wave, which grants access to the devil/angel room when completed. Each nightmare boss wave can spawn multiple bosses/mini-bosses at once. No coins are dropped during the nightmare wave.

Items that activate upon entering a new room will not activate when a new wave starts, making many items far less useful or outright useless.

For the first 8 waves, the clock will start at a set time and then increase by 1 second for subsequent waves. For The Basement and The Caves, the clock starts at 6 seconds. For The Depths, the clock starts at 5 seconds. For The 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.

Floors[edit | edit source]

Greed Mode has seven total floors, five of which are based off of floors found in the main game. These floors are The Basement, The Caves, The Depths, The Womb, 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.

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 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. In Greedier Mode, fewer coins drop, enemies can become champions, and Ultra Greed has a second form, Ultra Greedier.

Greedier Mode starts off with 9 waves when the button is first pressed instead of 8. 1 and occasionally 2 pennies will drop for each of the first 9 waves. The boss waves remain at 2. A total of 10 coins will drop for these boss waves. The nightmare boss wave remains at 1 and no coins will drop.

For the first 9 waves, the clock will start at a set time and then increase by 1 second for subsequent 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.

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.

When playing Greedier Mode, a small, red coin (Greedier mode only) will appear on the HUD, below the consumables.
