Introduction

In the current version of the game, there are a whopping 521 different co-op babies. Even though most of the babies are only cosmetic and have no special abilities, there are still 58 babies with special abilities. So a tremendous amount of work has gone into designing and coding the special babies, as well as creating all of the sprites. This is an entire area of the game that is unknown and unused by 99% of the player-base. It's time for that to change.

The Babies Mod

• Get the Babies Mod on the Steam Workshop: https://steamcommunity.com/sharedfiles/filedetails/?id=1545273881
• This mod provides a new character called "Random Baby". When playing this character, on every floor, you will be randomly assigned a baby from the list below. Each baby has a unique item or ability.
• Some babies are very strong, while others are very weak - you never know what you are going to get! But remember, they only last for a single floor.
• Due to the random nature of the babies, this mod should provide fresh experiences time and time again.
• More info:
  • Of the 58 co-op babies with special abilities, most were redesigned to be more interesting.
  • New abilities were created from scratch for the 462 cosmetic co-op babies.
  • Additionally, the 19 shooting familiars were added into the list, with new custom abilities for each.
  • There are 541 babies in total.

R+7 Season 5

• A lot of the babies will make you quite powerful, which can remove the difficulty of a normal Isaac run. Instead, challenge yourself to beat the game as fast as possible!
• And once you've gotten the hang of that, you can challenge yourself to beat the game as fast as possible 7 times in a row. This is traditionally referred to as a "multi-character speedrun", and it is a better test of skill than just beating the game really fast in a single lucky run. (Although, in this case, the terminology is confusing, because you are playing the same "Random Baby" character 7 times in a row, so it isn't technically a multi-character speedrun. But I digress.)
• The process of having to re-select the character from the menu in between runs can be completely automated by using a custom challenge in a separate mod called Racing+. (Racing+ is a mod that helps facilitate single-player speedruns as well as races between multiple people.)
• After subscribing to the Racing+ mod, simply choose the "R+7 Season 5" custom challenge to begin. (You can get to the custom challenges by pressing Tab on the challenges screen in the main-menu.)
• People around the world will compete to see who can get the best time using the custom challenge. The leaderboards can be found on Speedrun.com. (They are not quite there yet for Season 5 though, because the mod is currently in beta testing.)
• More information on the specifics of what the custom challenge does can be found at the Racing+ custom challenges documentation.
