Bloons Tower Defense 2 (also referred to with the retronyms Bloons TD 2 and BTD2) is an Adobe Flash game in the Bloons TD series developed by Ninja Kiwi and first released in 2007. It is built on Bloons Tower Defense and shares very similar gameplay, but introduces three new maps across three difficulty levels, a new tower type, two new Bloon types, and new placeable items.

Maps

There are three maps in the game, each corresponding to a different difficulty level. Harder maps increase the cost of all towers, upgrades, and placeables, and reduce the number of lives the player starts with. Bloons take the same amount of time to reach the exit on all maps. The user interface normally blocks the right side of the maps, though towers can be placed there with glitches.

Map	Properties	Description
Easy	Costs: ×0.9 Starting lives: 100	Easy has a cloudy blue background and a white path. Bloons enter from the left, round many corners, and exit at the bottom.
Medium	Costs: ×1.02 Starting lives: 75	Medium resembles the map from Bloons Tower Defense, but has a different layout. Bloons enter from the top-left, travel to the bottom over a bend, then travel straight up in the middle, then travel down again over a bend on the right side, and exit at the bottom-right.
Hard	Costs: ×1.04 Starting lives: 50	Hard has a sandy yellow background and brown paths. This is the only map in the game with two paths, which both start at the top and exit at the bottom, intersecting once on the left side, and have the same length. The left path reaches the intersection first.

Bugs and glitches

Incorrect sell values

The sell value of towers is derived from the base cost of the tower and its upgrades, not the actual amount of cash spent on them as determined by the difficulty level. For example, a 0-0 Dart Monkey always sells for $220 regardless of difficulty. This makes selling more valuable on Easy and less valuable on Medium and Hard than intended.

Upgrade stacking glitch

Main article: Upgrade stacking glitch

By pressing Tab until an upgrade button is highlighted and pressing Enter to purchase it, the player can purchase that upgrade multiple times on one tower. There's no limit to the number of times the upgrade can be bought and it doesn't stop if the player can't afford it, which puts their money into the negatives. The most useful application of this glitch is to use the Tack Shooter's Faster Shooting upgrade to increase its attack speed to the cap of 40 shots per second; this specific application is often called the "hypersonic Tack Shooter glitch".

MochiGames

Don't let any bloons escape - buy monkeys, tack shooters, cannons and boomerang throwers to help you. The sequel to the original bloons tower defense game.

Newgrounds / Armor Games

We had a huge response to the first game, most people seemed to have lots of fun despite the game being fairly easy by most td standards. We've added 3 new maps, one for three difficulty settings. We've also added a new tower type, the boomerang tower, as well as some new 'on track' items: Road spikes and Monkey glue. A sequel wouldn't be complete without more bloons of course, and we've added 2 nasty new types, the lead bloon and the rainbow bloon. Enjoy.
