About this project

Everest mod that puts other players in your map as ghosts you can see, chat and emote with. It does not sync the vanilla story, enemies or world state; shared-objective co-op comes only from map mods built on it plus Co-op Helper. Client v2.4.2 (GameBanana mod 53695, file dated 2024-12); source is MIT. Its README still links the download as gamebanana.com/gamefiles/12267, which redirects to that same mod page; GameBanana keeps Mod and GameFile IDs separate, so apiv11/Mod/12267 is an unrelated Team Fortress 2 mod and confused an earlier check.

About this project

Helper library for CelesteNet. Adds entities and triggers (spawn points, switches, gates and more) whose state synchronizes between players, which is what makes shared-objective co-op maps possible. Also ships a beta "Co-op Everywhere" mode that swaps supported vanilla entities for synchronized versions. Source on GitHub (corkr900); the GameBanana release v1.1.4 is CC BY-NC-ND 4.0. Partnership depends on it.

About this project

Two-player co-op Summit map, death-link style and aimed at Expert to Grandmaster players, by Clantis. Pulls a large dependency tree (fourteen helper mods including Co-op Helper and MaxHelpingHand), so it is much heavier to install than Partnership; treat it as optional. Release v1.1.3 (2026-10); the GameBanana release is CC BY-NC-ND 4.0. Its dependencies were not installed or tested here.

About this project

Two-player co-op mini campaign built on CelesteNet plus Co-op Helper, and the closest thing to a playable co-op campaign today. The mod page says it is designed for exactly two players, says it should not be possible in single-player, and recommends a private channel so only you and your partner share the map. Depends on MaxHelpingHand and LunaticHelper. Release v1.0.1 (2022-01); the GameBanana release is CC BY-NC-ND 4.0 and no source repo was found.
