Terraria

Terraria ( /təˈrɛəriə/ ^ⓘ tə-RAIR-ee-ə) is a 2011 action-adventure sandbox game developed by Re-Logic and published by 505 Games. The game features exploration, combat, crafting, building, and mining inside a procedurally generated 2D world. It has several world difficulties, as well as a character class system. The player can encounter a variety of enemies throughout the game, such as those who spawn at a certain time or location or during special events, and can also complete specific goals to attract non-player characters who sell items and offer services to the player. Terraria also features support for modifications through tModLoader.

Development began in January 2011 by Andrew Spinks of Re-Logic. Initially released in May 2011 on the Steam digital distribution service, Terraria has since received continuous content updates that have considerably changed the game from its first version. The game has also been ported to different platforms, including PlayStation 3, Xbox 360, PlayStation Vita, iOS, Android, Windows Phone, PlayStation 4, Xbox One, macOS, Linux, Nintendo 3DS, Wii U, Nintendo Switch, and Google Stadia.

Terraria has received generally favorable reviews from critics. Gameplay aspects, such as exploration, replayability, and amount of content, have been praised, while the crafting system has been viewed as being complex. The lack of a tutorial for PC has also been criticized; however, the tutorial worlds of Xbox 360, PlayStation 3, and PS Vita were commended. The combat system, as well as the controls for Xbox 360 and PlayStation 3, and the retro-styled sprites were also positively received. As of 2025, Terraria has sold over 64 million copies, making it one of the best-selling video games of all time. Re-Logic developed a separate game, Terraria: Otherworld, from 2015 until it was canceled in 2018.
