# Multiplayer roles

The Dedicated Server package introduces the concept of Multiplayer Role which describes the different roles that a Unity application can have in a multiplayer game. A game can have the following roles:
* Client role: This role is used by the players to play the game.
* Server role: This role hosts the game and runs the simulation.
* Client/Server role: This default role, also known as a listen server, is a type of server that contains a client.
