Terraria is a 2D action-adventure sandbox video game developed by Re-Logic. The game was initially released for Microsoft Windows in May 2011, and was later ported and released for Xbox 360, PlayStation 3, PlayStation Vita, iOS, and Android in 2013, for Windows Phone, PlayStation 4, and Xbox One in 2014, for OS X, Linux, and Nintendo 3DS in 2015, and for Wii U in 2016.
The game features exploration, crafting, construction, and combat with a variety of creatures in a procedurally generated 2D world. The game received positive reviews from critics, and over 18 million copies of Terraria were sold by July 2016.
The game starts in a procedurally generated world. The player starts with three basic tools: a pickaxe for mining, a shortsword for combat, and an axe for woodcutting. Many resources, notably ores, can be found while mining or exploring underground caves. The player begins with 100 health, which can eventually be increased up to 500 by finding special items underground. Some resources, and most items, may only be found in certain areas of the map, stored in common and rare containers, or dropped by certain enemies. The player uses resources to craft new items and equipment at an appropriate crafting station for that recipe. For example, tables or other items can be crafted at a work bench, and bars can be smelted from ore at a furnace. Several advanced items in Terraria require multiple crafting operations where the product of one recipe is used as an ingredient for another.
The player can encounter many different enemies in Terraria such as simple slimes, zombies, demon eyes, and various region-specific enemies. The occurrence of certain enemies depends on several factors including time, location, random events, and player interactions. The player can fight against enemies with swords, bows, guns, magic spells, and other weapons. Each map will have several zones with unique items and unusual enemies.
The player may also battle powerful boss monsters with a number of different combat mechanics, such as the Eye of Cthulhu and King Slime, that can drop rare items and large amounts of in-game currency. All bosses can be summoned by using certain items, destroying blocks through the world, or when certain criteria are met. Several of the bosses can spawn naturally in certain places and times. The defeat of these bosses is often tied to in-game progression. For example, the Dungeon is inaccessible before Skeletron's defeat, and it is unaffected by the activation of Hardmode until Plantera is defeated. Upon defeating Plantera, the difficulty of Dungeon enemies rises drastically with new enemies. Occasionally, the player will have to defend their base against invasions such as the Goblin Army and the Martian Invasion, or against events that affect the entire world, including the Frost Moon and the Solar Eclipse.
