What Is Unmoddable?

Updated

Unmoddable is a directory site that catalogs multiplayer and co-op mods for singleplayer games, plus the reverse category: singleplayer mods for multiplayer games. It also lists self-developed tools and modding tutorials. If you want to play a singleplayer-only game with friends, or you're looking for a mod that adds solo content to a multiplayer title, this site is built to help you find those projects in one place.

What Unmoddable covers

The site organizes mods into a few broad categories:

  • Multiplayer mods for singleplayer games — the main focus. These add online or local co-op to games that shipped without it.
  • Singleplayer mods for multiplayer games — the inverse case, adding solo-friendly content to multiplayer titles.
  • Self-developed tools — utilities the site's team builds themselves.
  • Modding tutorials — guides for people who want to make or adapt mods.

Each entry typically describes what the mod does, how many players it supports, and what gameplay systems it touches.

Examples of listed mods

The homepage surfaces a rotating set of projects. From the current listings:

Mod Game What it adds
Online Expedition Clair Obscur: Expedition 33 Real-time multiplayer; friends appear as animated players in Lumière and can join cooperative battles
Graveyard Keeper 2 Multiplayer Mod Graveyard Keeper 2 Online co-op for up to eight players sharing one world, each keeping their own character, inventory, and progression
CardShopCoop TCG Card Shop Simulator Co-op for the card shop management sim
Hades Co-op mod Hades Local and online co-op for two players, with local split controls and Steam Remote Play support
Rain Meadow Rain World Online multiplayer and co-op across Story mode, Arena battles, and the Meadow area
MegabonkTogether Megabonk Online co-op for up to six players over peer-to-peer netplay, syncing enemies, weapons, projectiles, chests, shrines, portals, and progression
Dark Messiah: Coop mod Dark Messiah Turns the singleplayer campaign into a co-op adventure with shared campaign saves and persistent character skills

The pattern is consistent: each entry targets a game that either lacks multiplayer or lacks singleplayer, and describes exactly what the mod changes.

When this site is useful

Unmoddable is worth checking when:

  • You want to play a specific singleplayer game with a friend and don't know whether a co-op mod exists.
  • You're comparing co-op options for a game and want to know player counts, save behavior, or which systems are synced.
  • You're looking for tutorials or tools to build your own multiplayer mod.

It is a catalog, not a download host or a launcher. Expect to follow each mod's own page or repository for installation files and setup instructions.

What to verify before installing

Because these are community mods, the details matter more than the listing itself:

  • Player count and connection type — some mods are local-only, some use Steam Remote Play, others use peer-to-peer netplay.
  • Save compatibility — mods like Dark Messiah's share campaign saves, while Graveyard Keeper 2's keeps separate inventories and progression per player. Check which model applies before starting a run with friends.
  • Version matching — co-op mods generally require all players to run the same mod version and often the same game version.

Start from the specific mod's page on Unmoddable, then confirm installation steps and current compatibility with the mod's own release notes.
