Multiplayer

Multiplayer is a game mode wherein Terraria can be played with or against other remote players.

Types
There are two types of multiplayer environments: Server and "Host & Play".


 * Host & Play games are started via the regular Terraria application. The first player chooses "Host & Play", chooses options, and starts the world, becoming the host. Other network or internet players can then join, by choosing "Join" from the multiplayer menu. The world shuts down when the original player exits. This option is normally for smaller local LAN games.
 * Major internet multiplayer games run on servers. Servers are started via the TerrariaServer.exe file included with each Windows Terraria installation, or via a third-party server program &mdash; see server for details. 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. Players can join server games by choosing "Join" from Terraria's Multiplayer menu, then entering the server information. Server lists can be found below.

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.

PvP


Player versus Player (PvP) is a multiplayer mode that allows players, or teams of players, to attack each other. PvP is activated by joining a multiplayer world and enabling the PvP option by clicking on the crossed swords in the upper-right hand corner of the screen. The only way a player can damage another player is if both have the PvP option enabled.

There is also the option of joining a team. Teams are represented by the colored shields in the upper-right corner of the screen. Once you select a team, there is an onscreen notification of how far away they are, as well as how much health they have. PvP players on the same team can see each other on the minimap, while other PvP players cannot.

Unique aspects of PvP play

 * The window of invincibility after taking damage is greatly reduced if it came from another player. Normally, you would receive 2/3 of a second of invincibility (0.66). In PvP, you only receive 2/15 of a second (0.13).
 * The Cross Necklace has no effect in PvP.
 * Players killed by other players do not drop coins.
