During a run, separate a defense shortfall from a lobby problem
Dome Keeper's main loop alternates mining with enemy attacks. Raw Fury's multiplayer overview describes co-op and versus as local or online modes, while the Steam page links the changing PC update history. Do not assume that a Steam PC guide describes console controls, cross-store invites or every multiplayer setup.
For a wave problem, identify what happened on screen: which enemies reached the dome, whether the shield was active or depleted, what weapon/gadget action you used, and whether a player was controlling the relevant input. For a session problem, record whether it failed before the lobby, at launch, or after gameplay began. These are different questions and require different evidence.
- Pause only when it is safe and note the exact mode (solo, co-op or versus), platform/store, displayed game version and whether the session is local or online.
- For a defense issue, record the dome, keeper(s), gadget(s), visible upgrades, wave number and the exact enemy or event that caused damage; do not infer a hidden damage formula from one loss.
- For a session issue, note host/client roles, invite path, whether both players can reach the lobby, and the first exact error or disconnect point. Do not post account identifiers or private invite links publicly.
- Check the official Steam announcement history for a patch matching the displayed build before applying an old forum workaround. A later fix may make an older report irrelevant.
- Use the report builder below to organize observations, then post only if you want to ask the external Steam community. Replies are player experience, not official support or verified facts.
Make the question reproducible, not just longer
A useful player report lets another person compare like with like. In particular, distinguish local co-op from online play and solo from co-op/versus; include the date/build visible to you and describe one symptom. The Xbox Wire article confirms the broad multiplayer options introduced in April 2026, but does not promise every cross-platform combination or network condition.
| If the symptom is… | Include… | Do not conclude… |
|---|---|---|
| Wave damage feels unexpectedly high | Mode, wave, dome, keeper, visible shield/weapon upgrades, enemy and observed sequence | That one setup is universally underpowered |
| A player cannot join | Platform/store for both players, local/online, host/client, exact stage and error | That cross-store play is supported unless official docs say so |
| A gadget or keeper behaves differently | Displayed version, DLC ownership, mode and current upgrade path | An older wiki or Reddit post is current |
| The issue began after an update | Before/after build if known, what changed, repeat steps | A patch caused it without a reproducible comparison |
Player discussion is an optional external destination
The Steam Discussions link is user-generated. GamerWin does not host comments or claim that an example report came from a real player. Remove usernames, account data, private lobby codes and unrelated screenshots before sharing; use the developer/publisher's official support route for account or purchase problems.

Before you play
- I recorded platform/store, mode and displayed version.
- I described one observable wave or lobby symptom.
- I separated local/online and solo/co-op/versus context.
- I checked official patch notes before repeating an old workaround.
- I understand the report stays in this browser until I copy it, and posting is my choice.
Frequently asked questions
Does the report builder contact other players?
No. It formats text locally in the current tab. You choose whether to copy it to an external discussion.
Does the April 2026 announcement prove every platform can cross-play?
No. It describes co-op/versus and local/online modes broadly. Check platform-specific official materials for the exact combination you want.
Is this guide verified against a live co-op session?
No. It is a source-based checklist; no lobby, network, defense run or player report was tested.
