Mods are packaged in a few different ways, partially due to what they rely on. However, all mods require BepInEx.

r2modman Packages

File Extension: zip

r2modman packages encompass all mods that can be used within r2modman. They may contain the formats below as well, but aren't required to.

Thunderstore Packages

Thunderstore packages are a subset of r2modman packages that contain additional metadata. All mods found on Thunderstore are Thunderstore packages. Much like how all squares are rectangles but not all rectangles are squares, all Thunderstore packages are r2modman packages but not all r2modman packages are Thunderstore packages.

BepInEx Plugins

File Extension: dll

BepInEx plugins have no additional requirements.

Deli Mods

File Extension: deli

Deli mods require Deli 0.4.1, but they may also rely on other mods. For instance, Deli mods that contain custom items or ammo also require OtherLoader.

Sideloader Mods

File Extension: hotmod or h3mod

Sideloader mods require Sideloader, which in turn requires XUnity.ResourceRedirector. These mods mostly replace assets, such as audio and textures, but can add items.

Asset Bundles

File Extension: none (shows as the FILE file type)

Asset bundles are loaded through OtherLoader's legacy loading system. These bundles are almost always a firearm, and are often accompanied with a .manifest file. This .manifest file is not needed for load the mod.

TnH Music

File Extension: .bank

TnH Music requires PTNHBGML.
