How to Change Max Players on Your Core Keeper Server

How to adjust the player limit on your Core Keeper dedicated server.

Via startup parameter:

-maxplayers 8

Or in ServerConfig.json:

"maxNumberPlayers": 8

Notes

Default is 8 players when -maxplayers is omitted
Core Keeper was designed for up to 8 players in co-op
Higher counts are technically possible but increase RAM and CPU usage
The config file defaults to 100, but the CLI default of 8 is the practical standard
