The debug console is accessible in The Binding of Isaac: Afterbirth † and The Binding of Isaac: Repentance . It is an extremely useful way to verify a particular game mechanic, explore a seed, or test various things about the game. Or, if you are a mod developer, you can use it to quickly test various things in your mods.
The debug console is only accessible if one or more mods are enabled. If you don't have any mods to enable, download one from Steam Workshop, or simply create an empty folder in your mods directory. Note that achievements will be disabled if Mom has not been defeated on the savefile, and consequently unlocks will not happen, donation machines can't be filled nor the will item collection page record anything. While many "enable debug console" mods exist on Steam Workshop, these do not explicitly enable the console or are required to enable it. ANY mod will enable the console, regardless of what the mod is named.
The debug console is only accessible by editing
options.ini in the configuration directory and setting the
EnableDebugConsole option to

Unlisted Commands[edit | edit source]
These commands do not appear in the console but can still be used.
|Restocks all shops.|
giveitem2 c105 g2 ipecac
|Same as giveitem but for a secondary character such as Esau.|
remove2 c1 r2 soy milk
|Same as remove but for a secondary character such as Esau.|
|Allows to set any room as "forced room". Said room gets weight of 1000, making it easier for it to appear on floor with |
addplayer 1 addplayer 6 1
|Spawns a new player entity (Isaac by default) with controls set to id 0 by default. You can specify player type and controller id in the command. If the player type is -1, the game will instead assign control to a random enemy in the room, similarly to the Friend Finder item.|
|Makes the game forget about the changes in current room and teleports Isaac back to previous room. Can be used to fix desynchronization issues if you use this command in a room where it happened. (Glowing Hourglass-like effect)|
|Prints a list of boss names and percentage chance (100%=10000) for current floor.|
netstart <steam_user_id1> <steam_user_id2> <steam_user_id3>
|Connects player(s) with specified Steam ID to your game (online multiplayer). Allows up to 4 players. You can also use aliases if you add them in steamids.txt file in your local savedata (where options.ini is stored) folder in following format:|
alias id alias id alias id (...)
Both you and other players should have Repentance opened (with --networktest parameter specified when launching the game). Achievements would go to the host if there was a way to access multiplayer without debug console. Can be unstable at times, so be careful.
|Changes network delay to a specified value. Can be useful if you see stutters during online gameplay.|
|Reloads wisps spawned by Book of Virtues and locusts spawned by Abyss.|

Trivia[edit | edit source]
- In Repentance, going to non-standard stages will crash the game.
- In Afterbirth+, going to non-standard stages will crash the game, with the exception of stage 13. It consists of 2x1 vertical rooms that have doors that only sometimes close, minimal enemies (usually a few of the same type), and uses Caves background. The music is a single layer of either the ???, , Basement or the Burning Basement music, and only plays when enemies are in the room. The boss is always The Duke of Flies, and no trapdoor or items spawn when the boss is defeated.
- Stage 13a is the same, but with Depths background. The boss is always Monstro II.
- Stage 13b is the same, but with Womb background. The boss is always The Duke of Flies.
- The enemy spawn patterns are the same as the waves in Greed mode, suggesting that this stage is used to store the waves in the game.
- The name display while holding Tab on PC/Back on Xbox 360/Touchpad or L2 on PS4/Minus on Switch will show up their respective overlay's stage name, but without the I or II, e.g. Normally it's Caves II, but in this stage is referred to only Caves, just like Cathedral, Sheol, ???, Chest, Dark Room and The Void, i.e Chapters 4.5 and above.
- Entering "stage 8" in Greed or Greedier mode will grant access to The Void. The rooms have random backdrops and the music is the same as The Void in regular mode, but the boss is Ultra Greed and will drop the Final Boss Chest. Entering The Chest will play the final ending instead of ending 18 or 19.
- Attempting to give yourself all the items using "giveitem *" will print the message "What are you trying to do?" to the console and will give nothing.
- Monster champion types go up to 48590, with anything beyond the 24 used types resulting in a monster that has double (maximum) HP, no other special abilities and often exotic color palettes not normally seen. Any higher will crash the game.
- Champions types above the 26 defined ones are mostly invisible and have no clear upper number, but may cause a crash at any time.
Bugs[edit | edit source]
|Bug!||If a champion is spawned via the "spawn" command, it will have the same amount of health as the non-champion version of that monster, unless the spawned champion variant has decreased amount of health.|
