Direct Answer
Current answer: Native multiplayer is not confirmed as available in the approved current sources. Steam announcements record multiplayer only as a future roadmap item, while the Nexus page describes a separate third-party co-op and versus mod. Do not treat either item as proof that official co-op can be played now.
The source snapshot was refreshed on 2026-08-20. It confirms the identity and status of the approved pages, but it does not establish live server support, a shipped native mode, a release schedule, or current mod compatibility. Check the linked pages again before acting on time-sensitive information.
Current Native Status
The approved record contains no publishable evidence that a native multiplayer menu, official co-op session, matchmaking service, or versus mode is currently usable. That absence is the current status statement; it is not a claim that development has stopped or that future support is impossible. A store description, community request, or mod listing cannot establish a native feature.
Mode: To be confirmed. Player count: To be confirmed. If a new menu appears after an update, verify it against a current official announcement before describing it as released support. Patch notes and the game itself take precedence over an old summary.
Official Future Roadmap
[A1] The Steam announcements source supports one careful statement: multiplayer appears as a future roadmap item. Roadmap language describes intent, not delivery. It does not confirm a mode, player capacity, test window, final design, or launch build, and it can change before implementation.
Release date: To be confirmed. The page therefore does not convert a plan into a calendar promise. Recheck the official announcement archive for an explicit release notice and confirm the feature in the current build before changing this status.
Third-Party Multiplayer Mod
[B1] Nexus hosts a community page whose author describes a multiplayer mod covering co-op and versus use. This is a third-party claim about third-party software, not an official game feature or developer commitment. Read the exact description, files, posts, changelog, and author notices on that page before downloading anything.
The archived record does not provide a safe publishable player limit or a stable mode list. It also does not prove that the file works with the current game patch. Treat screenshots, old comments, and earlier successful sessions as historical evidence only.
Dependencies and Launch Details
The Nexus author's instructions are version-specific and must be read as a set. A reference to BepInEx or launch arguments on that page applies only to the recorded mod instructions; it must not be generalized into a rule for the base game, the future official roadmap item, or every other mod.
BepInEx version: To be confirmed. Launch arguments: To be confirmed. Confirm the exact file version, dependency version, folder destination, and command syntax directly on the author page at installation time. Do not guess missing values or reuse commands copied from another game.
Known Evidence Limits
Current-version compatibility: To be confirmed. The source snapshot records only a version-specific third-party compatibility claim. It does not confirm support for every game patch, operating system, save state, network arrangement, or combination of other mods. The approved sources also do not establish official troubleshooting, moderation, privacy handling, or security review for community multiplayer.
When diagnosing a problem, separate the clean game, the mod loader, the multiplayer file, network configuration, and any additional mod. Change one variable at a time and keep notes. A failure in community software does not prove a defect in an unreleased official feature.
Backup and Removal
Before testing the mod, locate and back up saves and configuration outside the game directory. Preserve the downloaded archive, the author's installation and removal instructions, and a list of every file added or replaced. Start from a known clean state when possible, then verify normal single-player behavior before creating a modded session.
For removal, follow the author's current steps, remove only files known to belong to the mod or its documented dependencies, and verify the game files through the official store client if needed. Restore a backup only after preserving the newer save separately. Never assume that deleting one visible file reverses every change.
Sources and Labels
Grade A identifies an official channel. Grade B identifies a community-hosted third-party page. A confirmed source means the page was verified in the snapshot; it does not upgrade every claim on that page into an official or permanently current fact.
- [A1] Grade A · official source: Steam announcements. Used only for the future roadmap status. It does not confirm that native multiplayer or official co-op is currently released.
- [B1] Grade B · community source: Nexus multiplayer mod description. Used for the existence of an author-maintained third-party page and its version-specific claims; it is not official authority.
