How the Co-op Mods Listed on Unmoddable Differ

Unmoddable lists multiplayer mods for singleplayer games, and the co-op entries differ mainly in four ways: how many players they support, how players connect (online, local split-screen, peer-to-peer, or Steam Remote Play), how much they change the base game, and how they handle saves and progression. If you are deciding which mod fits your group, check those four dimensions against your situation — a two-player local setup and an eight-player online group need different mods.

Player count

The listings show a wide range, so match the mod to your group size before anything else.

Where the count is not stated, treat it as unconfirmed and check the mod's own page before planning a session.

Connection method

The listings describe several distinct ways to play together, and they are not interchangeable:

• Online co-op — Graveyard Keeper 2 Multiplayer Mod, Rain Meadow, and MegabonkTogether are described as online.
• Peer-to-peer netplay — MegabonkTogether specifically uses peer-to-peer, which matters if you want to avoid a central server.
• Local split controls and Steam Remote Play — Hades Co-op Mod supports both, so two players can share one machine or stream it.
• Real-time multiplayer — Clair Obscur: Expedition 33 Online Expedition adds real-time multiplayer so friends explore Lumière together.

If your group is split across locations, local-only options are out. If you want to play on one couch, the Hades mod's split-controls support is the relevant detail.

How much the base game changes

Mods sit on a spectrum from "minimal touch" to "restructured campaign":

• Minimal changes — Hades Co-op Mod is described as designed with minimal gameplay changes, so the original feel is largely preserved.
• Added multiplayer layer — Clair Obscur: Expedition 33 Online Expedition adds real-time multiplayer to an existing atmospheric RPG, letting friends appear as fully animated players in the world and team up for cooperative battles.
• Campaign converted to co-op — Dark Messiah Co-op transforms the original single-player campaign into a cooperative adventure, adding cooperative features on top of the story.
• Shared-world management — Graveyard Keeper 2 Multiplayer Mod brings online co-op to the management adventure, with players working together on construction.

The more a mod restructures the campaign, the more likely it changes how the game feels solo. If you want the vanilla experience intact, the minimal-change options are the safer pick.

Saves, progression, and inventories

This is where the mods diverge most for long-term play:

• Individual progress kept — In Graveyard Keeper 2 Multiplayer Mod, players keep their own characters, inventories, and progression while sharing the same world.
• Shared campaign saves — Dark Messiah Co-op has players progress through the story together while sharing campaign saves, plus persistent character skills.
• Synchronized systems — MegabonkTogether synchronizes most core gameplay systems, including enemies, weapons, projectiles, chests, shrines, portals, and progression.

The practical question: if one player misses a session, do they fall behind? Shared saves and synchronized progression keep everyone level; individual inventories and progression let people play at their own pace but can create gaps.

Choosing by situation

• Large online group (6–8 players): Graveyard Keeper 2 Multiplayer Mod (eight) or MegabonkTogether (six, peer-to-peer).
• Two players, one machine or remote play: Hades Co-op Mod, which supports local split controls and Steam Remote Play.
• Want the original game mostly untouched: Hades Co-op Mod (minimal changes) or Clair Obscur: Expedition 33 Online Expedition (adds a multiplayer layer rather than rewriting the game).
• Want a full campaign played together with shared saves: Dark Messiah: Co-op.
• Want everyone to keep their own character and inventory: Graveyard Keeper 2 Multiplayer Mod.

What to verify before installing

The Unmoddable listings give you the headline features, but several details are not stated for every mod — player counts for Clair Obscur, CardShopCoop, Rain Meadow, and Dark Messiah, and connection methods for several entries. Before committing a group to a mod, confirm on the mod's own page:

1. The exact maximum player count.
2. Whether it is online, local, or both.
3. Whether saves are shared or per-player.
4. Whether host and clients need the same mod version.

Unmoddable's stated scope is to list multiplayer mods for singleplayer games, singleplayer mods for multiplayer games, self-developed tools, and modding tutorials, so the site is a starting index rather than the final word on compatibility.
