GoreBox multiplayer and Photon setup

Official servers are gone. What happened, and the Photon setup that lets you play GoreBox with friends.

Updated 2026-09-07

On 11 March 2026 F²Games posted an update titled "An Important Update on GoreBox Multiplayer" and removed the public multiplayer mode from the game. The reasons given were exploiters, bot raids on the servers and the Discord, and security vulnerabilities that needed fixing properly rather than patched over. Multiplayer is expected to return in the GoreBox 26 rebuild, with no date attached.

What's left is a friends-only mode that works through Photon, the networking service the game was already built on. Instead of F²Games paying for one big Photon account that everyone shares, you create your own free one and plug its keys into the game. Anyone using the same keys can join you.

Photon setup, step by step

You'll need a PC or a phone browser and about ten minutes. One person in the group does this; everyone else just needs the IDs.

Go to photonengine.com and create a free account. The free tier allows 20 concurrent users, which is more than a GoreBox session needs.
In the dashboard, click Create a new app.
Set the type to Photon PUN (some builds of GoreBox accept Fusion instead; if PUN doesn't connect, try that). Name it anything. Create it.
Create a second app of type Photon Voice if you want in-game voice chat. Skip it if you don't.
Each app shows an App ID, a long string of letters and numbers. Copy both.
In GoreBox: Settings → Account and Multiplayer. Paste the PUN ID into the main app ID field and the Voice ID into the voice field. Save.
Set your region to match the one your Photon app was created in (or set it to Any if you can't tell).
Send the same two IDs to your friends. They paste them in the same place.
Host a room. Everyone with matching IDs and region sees it in the room list.

Treat your App IDs like a password. Anyone who has them can join your sessions and burn through your free tier. Share them in a private message, not a public server.

Errors and what they mean

Message	Cause	Fix
Server does not exist	Region mismatch between host and joiner	Both switch region to Any, then back to the same region.
No account ID / can't join	The game failed to generate a local ID	Change your nickname in Settings a couple of times, restart the game. This is an old bug and the workaround still applies.
Account banned (never played online)	ID bug from early 2025	Appeal in the game staff Discord.
Connecting… forever	Wrong app type or typo in the ID	Re-copy the ID; try Fusion instead of PUN.
Can't hear anyone	No Voice app ID	Create a Photon Voice app and paste its ID.

Android vs PC

The Photon fields exist on both. It's easier to set up on PC because you can copy and paste. On Android, use a password manager or paste from your notes app; typing a 36-character ID by hand is where most people go wrong. Cross-play between Android and PC works as long as everyone is on the same game version.

A short history of GoreBox multiplayer

Public servers launched with the Animosity build in 2022. Cheating got bad enough that mobile multiplayer was pulled for a period, then restored in v15.16 after an anti-cheat pass. v15.17 tried a ticket system where watching an ad bought 15 minutes of online time; players hated it and it was removed a patch later, replaced by a single ad before joining. Through 2025 the game fought waves of exploiters, and by March 2026 the studio decided to rebuild rather than keep patching. That is where things stand today.

Common questions

Is there any public server list now?

No. Every session is private to whoever shares the same Photon keys. Some Discord communities post shared keys, which works, but you get the same griefing problem that got official servers shut down.

Does the Photon free tier run out?

It's capped by concurrent users (20), not by hours. For a friend group it never runs out.

Will my old multiplayer stats come back?

Unknown. F²Games hasn't said whether GoreBox 26 will carry anything over.
