History of Bloons

Bloons Tower Defense (also known as Bloons TD) is a series of tower defense games under the Bloons series created and produced by Ninja Kiwi. The game was initially developed as a browser game, built upon the Adobe Flash platform and released in 2007. Later games in the series expanded to support various mobile platforms, including Android, iOS, Windows Phone, PlayStation Portable and Nintendo DSi.

In the game, players attempt to prevent balloons (called bloons in-game) from reaching the end of a set course by placing towers or road items along it that can pop the bloons in a variety of ways. Some towers can stall the bloons and give the other towers more time to pop them by freezing and gluing the bloons. Money is gained by popping bloons, completing levels, and collecting bananas from existing farms and can be spent on new towers, upgrades for existing ones, or temporary items such as exploding pineapples and road spikes.

Bloons Tower Defense and Bloons Tower Defense 2

Bloons Tower Defense is the first game in the BTD series, released for free as a flash browser game in Mid 2007. In the game players had to defend against coloured bloons with monkeys, dart throwers, and other towers positioned around the map. When strong bloons are popped they release weaker ones until eventually completely popping. If all lives are lost, the game is over. If all waves are passed, the player will win the game.

Bloons Tower Defense 2 was released soon after in Late 2007, adding new towers, multiple map options, new bloons, and an option for game difficulty.

Bloons TD 6

Bloons TD 6 is the newest game in the Bloons series. After being announced on March 28, 2017 on PRLog, it was released for the iOS App Store and the Google Play Store on June 14, 2018. A Steam version was released on December 17, 2018. Unlike earlier games, Bloons TD 6 does not have a counterpart on the Ninja Kiwi website.

New features in Bloons TD 6 include new 3D graphics, obstacles that block a monkey's sight, a new monkey knowledge system, two new regular towers (the Druid and Alchemist), a new type of tower called heroes, a fortified bloon property, purple bloons, a new MOAB-Class bloon called the B.A.D, and 5th tier and 3rd path upgrades for every tower.

The fortified property acts as a "band" that makes the bloons more powerful; it doubles the amount of damage needed to take down that bloon. Fortified bloons also carry on the property to a bloons' "children". The bloons able to have the property are lead, ceramic, and any MOAB-class bloon.

In "Bloons TD 6", heroes were introduced, a special type of tower that levels itself up and can upgrade without player input; only one hero can be used per game, and it is preselected beforehand. Each tower has unique abilities and moves. There were four heroes released when first launched: Quincy, Gwendolyn, Striker Jones, and Obyn Greenfoot. Captain Churchill, Benjamin, Ezili and Pat Fusty were added as new heroes in later updates.

Cosmetic “skins” have also been added to Quincy, Gwendolyn, Captain Churchill, Striker Jones and Obyn Greenfoot in order of release date. Quincy’s skin is Robo-Quincy, a cyborg version of himself. Gwendolyn was turned into Scientist Gwendolyn, a scientist-themed version of her with blue fire. Captain Churchill has Sentai Churchill, a Super Sentai or Power Rangers themed skin with an arcade-like feel. Striker Jones’ skin is Biker Bones, a biker skeleton with flames. This is a reference to the B Emoji meme started in the subreddit, when Jones was the worst hero of the four. Obyn Greenfoot's skin is an Ocean Guardian skin, a watery makeover with a pink shark spirit to boot.
