📋 About This Mod

Core R2API module

🤖 AI-enhanced — based on mod data

R2API_Core is the essential backbone of the R2API framework for Risk of Rain 2, providing core utilities and tools for other submodules. It doesn't change gameplay itself but is required for most R2API submodules to function. With 700k+ downloads and frequent updates, it's a must-have for modded setups.

✨ Key Features

Core module of R2API, providing the framework for all other submodules
Includes utilities like CompressedFlagArrayUtilities and SystemInitializerInjector
Necessary for most R2API submodules to function properly
Frequently updated to maintain compatibility with game updates and DLC
Documentation available via included xmldocs and dedicated wiki

📊 Pros & Cons

✅ Pros

  • Massive adoption with 700k+ downloads, proving it's the standard for R2API mods
  • Actively maintained with recent updates for game patches and DLC
  • Essential for modders and players using R2API submodules, ensuring stability

⚠️ Cons

  • Does nothing on its own—you need other mods that depend on it to see any effect
  • Endorsement count is low (19) relative to downloads, suggesting it's a behind-the-scenes dependency rather than a fan-favorite
  • Requires RoR2BepinexPack as a dependency, adding an extra install step
🎯 Is This For You?
This is for mod developers building on R2API and players who install mods that require R2API submodules. If you're a casual player just adding a few mods, you'll likely need this as a dependency but won't interact with it directly. For mod authors, it's the foundation you build upon.
📦 Install:Easy· Under 1 minute

💡 Beginner Tips

  • Make sure you have BepInEx installed first, as R2API_Core requires RoR2BepinexPack to run.
  • If a mod says it needs R2API, install this core module and any specific submodules it asks for—don't skip it.
  • Check the R2API wiki or modding discord if you're developing your own mods and need to understand the API.
