About Tower Defense
Tower defense or TD is a subgenre of real-time strategy computer games. The goal is to try to stop enemies from crossing the map by building towers which shoot at them as they pass. Enemies and towers usually have varied abilities and costs. When an enemy is defeated the player earns money or points, which are used to buy or upgrade towers.
The choice and positioning of the towers is the essential strategy of the game. Many games feature enemies that run through a "maze", which allows the player to strategically place towers for optimal effectiveness. However, some versions of the genre force the user to create the maze out of their own towers. Some versions are a hybrid of these two types, with preset paths that can be modified to some extent by tower placement.
Originally, it was first called Turret defense.
How it all began?
We can say that Tower defense games started its roots in Rampart; a classic strategy arcade game that was release on 1990. The game involved defending a castle by placing cannons, and making repairs between several rounds of attacks.
At the start of the year 2000, tower defense games began to appear as custom or user-created maps in Starcraft, Ages of Empires II and also in Warcraft III. But the first standalone PC tower defense game was Master of Defense, a 3D shareware game that was released on 7 November 2005. It was so popular that it received several awards.
Then, many game developers began designing games using Adobe Flash to create stand-alone game on web browsers, which led to the release of Flash Element Tower Defense in 2007and also Desktop Tower Defense on the same year. Desktop Tower Defense became a hit that it led to the creation of a mobile phone version of the game. Other notable tower defense games that became popular include Protector, Immortal Defense and GemCraft.
In 2008, the tower defense's big success led to the porting into console gaming such as Defense Grid: The Awakening on the PC and Xbox 360, and PixelJunk Monsters and Savage Moon for the PlayStation 3 Tower defense games have also appeared on handheld game consoles such as Lock's Quest and Ninjatown on the Nintendo DS, and Crystal Defenders for the iPhone/iPod Touch.
Different types of Tower Defense
Tower Defense games have different types or mode of gameplay, so here are some of the most notable types:
Maze - Waves spawn from one end of a maze then crawl down the path to the other end. Usually the main base is their target (commonly located in the middle of the map). It is your job to make sure the creeps don’t get to the base. This can be done by building defense towers along the path to attack the waves of incoming monsters. Some Maze types can be played solo or with co-op.
Mauls - These games are similar to the traditional maze Tower Defense games. The only difference is the mazes are much wider and you build towers inside the mazes rather that on the edges. This style can be much more strategic. Not only do you need the right combination of towers at the right times. You also need to design an effective maze within the maze.
Tower Wars - Tower wars can be played on either the maze style or the maul style game. They can also be played co-op or solo. The major difference is that the monsters are spawned by the teams to go through the mazes of other teams.
