Player versus player (PvP) is a multiplayer mode that allows players, or teams of players, to attack each other. Note that Expanded Worlds hosted by New Nintendo 3DS or 2DS systems will prevent users with a Original 3DS or 2DS from joining, as those systems do not support the Expanded World feature.

Up to 4 players can join a world at once. Players who want to join a world can select 'Join World' and select the preferred world from the list.

After selecting a character, the player can choose 'Multiplayer' and 'Start Game' to host a world locally.

To host a LAN World, the device will have to have at least 1 GB of RAM.

There is a maximum of 8 players allowed in one world. Third-party applications exist to forward these games over the internet rather than just over a single network, such as Multi Terraria or Terraria MP, but others are unsupported and come with no guarantee. Then the screen will read: 'Searching for local hosts.', or if the 'online' button was pressed then it will just wait until it finds someone.

The player will need to press 'Multiplayer', and then press on their preferred character.

In server multiplayer games, the host server provides the world file, and has the ability to communicate with players, save the map, close the server, set the time of day, and kick or ban players. Server lists can be found below, in the 'Server lists' section on this page. Players can join server games by choosing ' Join via IP' from Terraria's multiplayer menu, then entering the server information. A server allows the game world to run on a separate computer, with no graphical requirements, and without requiring any particular player to remain connected. Servers are started via the TerrariaServer.exe file included with each Windows Terraria installation, or via a third-party server program – see server for details.

Servers: Major internet multiplayer games run on servers.

This option is normally used for smaller LAN games or for small online games. The world shuts down when the original player leaves the world. Other network or internet players can then join, by choosing ' Join' from the multiplayer menu or ' Join via Steam' if they are friends on Steam. The first player chooses ' Host & Play', chooses options, and starts the world, becoming the host.

Host & Play games are started via the regular Terraria application.There are two types of multiplayer environments: Server and 'Host & Play'. See also: Guide:Setting up a Terraria server and Guide:Setting up Steam Multiplayer Desktop/Console
