Terraria is an action-adventure/RPG indie game, released by independent game studio Re-Logic - it is available via the Steam Store, Xbox Live and the Playstation Network. The game features exploration, crafting, construction, and combat with a variety of creatures in a randomly generated 2-D world.
Released for PCs on May 16, 2011, the game is estimated to have sold about 50,000 copies during its first day of release, with over 17,000 players online at the same time during the first day's peak. Over the week, 200,000 copies of the game were sold, making it the top-selling game on Steam for the week, ahead of The Witcher 2 and Portal 2. It remained number one on Steam for the first six days of its release, and as of January 2013 has sold over 2,000,000 copies. The game was released on PlayStation Network and Xbox Live Arcade (Worldwide except for Europe and Australia) at the end of March 2013 with exclusive content. The PS3 European and Australian release date was May 15th 2013. It was announced on March 28th 2013 that Terraria is coming to the PS Vita in Summer 2013.
Terraria is noted for its classic exploration-adventure style of play, similar to titles such as Metroid and Minecraft. Basic gameplay features day and night cycles, nocturnal and subterranean attackers, world-building elements, and character advancement. The game has a tile-based graphical style reminiscent of the 16-bit sprites found on the SNES.
At character creation, each player has a copper axe, a copper pickaxe, and a copper shortsword. They start out with 100 health. When the character first spawns in a new world, an NPC, the Guide, appears nearby to explain the basics of gameplay.
There are three character difficulties: Softcore, Mediumcore, and Hardcore. They vary only in death penalties. In Softcore, characters drop half their coins. In Mediumcore, characters drop all their items including coins and ammo. In Hardcore, characters die permanently, dropping all their items and becoming ghosts, unable to alter the world. When a player on hardcore difficulty dies, their character is deleted.
At night, different things may appear, such as Zombies and Demon Eyes, who will constantly attack the character until morning. At dawn, they all run away, even if they are still attacking the character. Daytime creatures are limited to gentler slimes. However, different biomes may contain powerful monsters including giant worms and hornets, while enemies progressively get harder as you travel deeper. Each night, given certain fulfilled requirements, there is a one in nine chance there will be a Blood Moon. Blood Moons spawn more enemies and rarer, extra ones as well (such as the Groom) and give zombies the ability to open doors, as well as many other subtle changes, like NPC dialogue and shop inventory. For example, female NPCs seem more grouchy, and the Dryad NPC sells corrupted items instead of corruption reducing items, and may quote, "I sell what I want! If you don't like it, too bad."
Characters may also summon powerful boss monsters, such as the Eye of Cthulhu or the Eater of Worlds. Independently of summoned bosses, each map has a dungeon that contains rare items and unusual enemies, and can be safely entered only after defeating the Skeletron boss guarding the dungeon on that map. Defeating the Wall of Flesh turns the current world into hardmode, which contains new enemies, blocks, biomes, items, and more. Hardmode bosses are more or less mechanical and harder versions of the original bosses. Hardmode also quickly brings about the removal of most forest biome and replaces it with either Hallowed or Corrupt biome. Weapons during hardmode are also much more powerful and/or sophisticated.
Unique features 
Beyond basic gameplay features, Terraria has several elements not present in the games from which it takes its inspiration. By completing specific goals (such as defeating a boss, or gaining an extra heart), characters can attract NPCs to occupy structures or rooms they have built, including the Merchant, Dryad, Demolitionist, Arms Dealer, Clothier, Nurse, Mechanic, Wizard, Goblin Tinkerer, and Santa Claus. Santa Claus is only available during the Christmas holiday season (December 15–31). Some NPCs need to be unlocked by finding them and untying them first, but also must have a valid house to live in built by the player. Characters may then buy equipment or misc items with coins gained from defeating monsters, selling items, breaking pots, or finding treasure chests hidden within the world. Each map also contains partly random generated biomes with unique monsters and surroundings, such as the Underworld (a lava-filled chthonic area filled with demons and skeletal serpents), the Hallow, a colourful but dangerous biome which is generated after the Wall of Flesh is killed, the Corruption (a dangerous, diseased wasteland full of deadly creatures and chasms full of rare items), Floating Islands which contain a chest of different quality, deserts, and jungles above and below ground.
Random events may occur in the course of play, such as the Goblin Invasion or the Frost Legion which sends a goblin army or snowmen (respectively) to lay siege to the characters' houses, although the latter is only available to fight within the month of December along with the unique NPC Santa Claus . Events such as meteorites falling, generating meteorite ore, can also be caused by destroying shadow orbs in corrupted map areas (biomes) and creating certain boss-summoning items at demon altars, among others. There are also some monsters considered mini bosses such as the wizard Tim, The Groom, Doctor Bones, the King Slime and in Hardmode, Wyverns.
Resource gathering 
Player characters primarily gather resources in Terraria using three basic tools. The solid soil- and brick-based blocks which make up the two-dimensional world can be mined using a pickaxe, trees and certain other structures can be cut using an axe, and background wall tiles, fixtures (such as crafting stations), and other "placed" objects can be deconstructed with a hammer. The Hamaxe is a combination of a hammer and an axe, which can only be made out of some of the rarer materials; it saves inventory space by eliminating the need for both tools as separate items. The speed and ability to deconstruct certain objects (such as iron ore) with which each tool can be used to harvest resources from the environment depends on the quality of the material the tool is made from and the modifier (randomly generated rating of the weapon, tool or accessory such as "legendary" or "broken") applied to that item. Wooden and Copper tools (low-quality materials) harvest resources very slowly, but tools made out of higher-quality material (e.g. Demonite, Gold, Hellstone etc.,) can harvest most resources in one or two swings. Thus, as characters acquire better tools, their rate of potential resource acquisition also increases. In order to get better items and materials, better tools are required. After defeating the Wall of Flesh, upgraded mechanical versions of the previous tools become available. The drill replaces the pickaxe and the chainsaw replaces the axe. Finally, the Hamdrax is the functional combination of a hammer, drill, and chainsaw. Reforging via the goblin tinkerer gives a new random modifier to the item at a cost of five times the sell price of that object in coins. Characters can also obtain resources from slain enemies, from within chests and clay pots found underground, and from most NPCs.
Harvested resources can be crafted into new items and equipment through the inventory screen by standing in front of the appropriate crafting station and selecting the appropriate recipe, provided one is carrying the correct ingredients with them for that recipe. As long as the necessary ingredients are present, new items can be made just by clicking their recipe, as opposed to the often-compared game, Minecraft, in which one must visualize and "draw" the item with the ingredients. There are several types of crafting stations, and most items must be created at a specific crafting station. Some important and powerful items are only available via crafting. If provided with a possible ingredient, the Guide lists all possible items that can be crafted from that ingredient—or players may mix and match items to discover new recipes.
Terraria was developed by Re-Logic, with development starting in January 2011 and is built on the Microsoft XNA framework. The game was released on May 16, 2011. Re-Logic is composed of Andrew Spinks, who designed and programmed the game, and Finn Bryce, who along with Spinks did the graphic design for the game. The music was composed by Scott Lloyd Shelley through his Resonance Array studio.
As of February 2012, the developers announced that they would not be continuing active development, but would release a final bug-fix patch. However, 505 Games is porting the game to several video game consoles and adding new content. 505 Games does not have the rights to update the PC version.On 24th January 2013, Andrew Spinks requested suggestions of features for possible future updates to the PC version. This question was put to people on the official Terraria forum.As of April 3rd 2013, Andrew posted a spoiler on the possible update for Terraria, showing the possibility of the update. More information on the 2013 PC Update can be found in the FAQ.
