# Network Protocol The Robot Devastaton server has two main communication channels: * A broadcast channel, that periodically sends information about the logged in players to all the players. * A [RPC server](https://en.wikipedia.org/wiki/Remote_procedure_call) that waits for commands. Players sent those commands to keep the server informed of all the game events. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
