Soul Link

Your fates are bound. Only together can you be free.


Soul Link is a multiplayer mod for The Binding of Isaac: Repentance that connects two or more (up to 4) players' solo runs into a shared experience of strategy, sacrifice, and synchronicity. Each player plays their own run—but every item, every heart, every boss fight is tied to their partner’s journey. What happens to one, happens to all.

Warning:

This mod is currently a beta release! There can and will be bugs, as well as feature updates. If you encounter a bug, please report it on the Discord[discord.com]!

Just a short list of features in the mod -- with many options to customize how linked you truly are.

• Item Sync: Your pickups are linked, and limited. Replace yours? They lose theirs too.
  
• Shared Damage and Heals: You feel what they feel, they feel what you feel.
  
• Progression Lock: The further you get, the more item slots you get.
  
• Active Items: Can’t use it until both of you have one.
  
• Revival: Revive your friends, but it comes at a cost.
  

Follow the following steps to get started -- please note that these steps are required for networking to get enabled in The Binding of Isaac:

1. Subscribe to the mod here in the Steam Workshop
   
2. Configure Isaac to enable networking by enabling lua debug mode:
   
   • In your Steam Library, click on the gear icon on the Binding of Isaac page, and select Properties from the dropdown.
     
     
   • On the properties screen, enter --luadebug in the Launch Options input. (note to use double hyphens!)
     
     
   • Close the properties window.
     
3. Start Isaac, and start a new run with the Soul Link character.
   
4. Hold the map button to display the Quick View interface to see the stats of your co-players.
   

If you need assistance in getting things setup, detailed instructions to complete the luadebug step can be found on the Soul Link website[soullink.gg]. Alternatively, you can join the Discord[discord.com] to seek further help.

The --luadebug parameter passed to Isaac, allows mods to operate in debug mode. In this mode, mods have additional functionality that is normally locked by the modding API's sandbox. The Soul Link mod requires internet connectivity to work, as it interacts with the main server, and provides a bridge between players. You need to be aware that enabling luadebug also gives mods unrestricted access to your file system and internet -- it will enable this functionality for ALL mods you have installed. There is a risk in enabling this mode, and a malicious mod could leverage this functionality to cause your system harm.

Please only enable luadebug if you trust the mods installed on your machine, INCLUDING SOUL LINK. As a precaution, it is recommended to disable other mods to limit your risk while playing with Soul Link. Additionally, you should disable luadebug (by removing that flag from the parameters screen) when you are not using Soul Link.

The mod has been tested in Repentance and Repentance+; while it might work in other versions, this will most likely not be tested fully, and compatibility might be spotty. This mod will NOT work with REPENTOGON due to it not having a working socket library _at this time_.
