Risk of Rain 2 Modding on OpenMods

Risk of Rain 2's BepInEx + r2modman scene

Risk of Rain 2 (2019) is Hopoo Games's third-person roguelike shooter. The modding scene is built on BepInEx + R2API (a community framework) + r2modman (the same mod manager used for Valheim, Lethal Company, and other Thunderstore games).

The catalogue is large: custom survivors, item additions, prismatic trials variants, balance overhauls. Most mods run through R2API's content registration system, which makes them broadly compatible with each other.

The toolchain

• r2modman: community mod manager, Thunderstore-based.
• BepInEx (Mono build): the foundational loader.
• R2API: content framework most mods depend on.
• Thunderstore: distribution hub.

What you'll find on OpenMods

RoR2 mods live primarily on Thunderstore (with some on Nexus). GitHub hosts source for R2API and many of the larger mods. OpenMods catalogues GitHub-published RoR2 mods.

Practical notes

• Multiplayer with mods. All players need identical mods at identical versions. r2modman handles this via profile sharing.
• Survivors of the Void / Seekers of the Storm DLCs. Most modern mods support both base game and DLCs. Check compatibility tags.
• Game updates break things. RoR2's update cadence is moderate. Most popular mods update within days.
• r2modman profiles share via code. Coordinate with friends by exporting a profile code.
