Terraria can be played in single or multi-player modes (with players that they may not know personally). They can join or host servers (a computer or device used to host games) to play with others online.
There is an in-game chat feature that allows players to communicate and apps such as Discord can be used for voice chat. There are currently no in-game purchases available on Terraria.
Terraria does not have parental controls features and there are limited safety settings available. Parents should explore the safety settings available on the gaming platform used to play Terraria on (e.g. iOS) to activate such settings. They can also visit the Terraria Forums page to seek support if encountering problems in the game.
