Terraria

Terraria ( tə-RAIR-ee-ə) is a 2011 action-adventure video game developed and published by Re-Logic. As a sandbox game, Terraria has no set goals. After creating the player character and choosing the game's difficulty, the player is placed in a two-dimensional, procedurally generated world where they explore, fight enemies, gather resources, and craft equipment. Players beat bosses, a tougher variety of enemies, to gain access to more items, resources, and equipment. By completing select goals, players receive access to non-player characters (NPCs) who sell items and offer services, such as healing and fishing quests. Terraria can be played alone or with others, and features support for modding.

Andrew Spinks commenced development in January 2011; he was assisted by a team of game testers and designers. As of 2025, Terraria is developed by eleven members of Re-Logic. Initially released in May 2011 on the Steam digital store, Terraria has received continuous content updates that have considerably changed it from its first version. The game was originally set to end development in 2012, but it resumed in 2013.
