How many players can be in a ROB RUN party?

Up to 3. Kefir tested larger parties, found they reduced random encounters, and is not expanding party size for now.

How do I play with more than 3 friends?

Use a clan, which holds up to 100 players. Clans exist only on the server you chose.

Rob Run How to Play With Friends: Parties and Servers

As of November 13, 2026.

Party and clan limits

The party limit is 3 players. Kefir says it tested bigger parties and found they reduced random encounters, so it will not expand party size for now. For bigger groups, clans hold up to 100 players (Kefir, October 2). Solo and duo players start with higher Notoriety (level 4) than full parties, according to Kefir's November 13 FAQ.

Check your server first

Both players must be in the same region, either EU or East US. Check the server ID on the map. DTGRE says that if the IDs match, you can press Tab, open Party, and invite your friend by player ID or from your Steam friends, without surrendering.

If you are on different servers

The Help Center's steps:

Open the global map and choose Prison.
Click "Surrender to Feds".
Switch to your friend's server.
Send the party invite again. Invites sent before the switch will not work.

Party members must be on the global map to enter a location together, and some locations block invites (robrungame.com FAQ, fan source).

The cost of switching

Guides disagree about what surrendering costs. GamerBlurb says it is not confirmed whether you keep your inventory, while DTGRE and XboxPlay.games say you lose your progress. Both advise letting the player with the least to lose make the switch, and XboxPlay.games notes that starting together on a fresh server avoids losses. Details are in how to change servers.

Not officially confirmed yet

The surrender penalty, and any way to join a friend without changing servers.
