About Terraria

Terraria is an action-adventure 2D sandbox game developed by Re-Logic. The game was first released for Microsoft Windows on May 16, 2011 and has since been ported to several other platforms including game consoles, smart phones, and tablets.

In the 2D sandbox world, players can explore the game contents, make crafts, build houses, and combat with a variety of creatures.
