NinjaKiwi's Bloons Tower Defense 4 is here at last, stepping over Bloons Tower Defense 3 and adding much more of everything we love! New units, new maps, better upgrades, and more evil bloons to pop!

Bloons Tower Defense 3 has finally been released after months of anticipation from all the hardcore Bloons fans out there. Picking up where Bloons TD 2 left off, the new game features even more tracks (eight in all!), new monkeys (towers) and upgraded gameplay mechanics.

Do you like cake? Do you like double-decker cake? We are about to lay on you a triple-decker cake, with helium! When you eat this triple-decker cake, and then attempt to speak, your voice will sound squeaky and distorted. For lo, besoothe thee, from Ninja Kiwi comes the final installment of a trilogy that may well become a tetralogy if its popularity continues at this pace!

Hot on the heels of the original Bloons Tower Defense game comes a sequel that delivers more of the same explosive fun the original packed, and yet with 3 new difficulty levels and more tower types than ever before. Like the new Road Spikes that you can use to pop any remaining bloons if it looks like some will escape. And the update promises to provide a greater challenge than the first one did.

Bloons Tower Defense takes the Bloons concept—popping balloons, preferably with monkeys involved—and spins it in a new and intriguing direction. It's your standard tower defense game but with monkeys popping balloons with darts and various other sharp instruments. It's a flawed but engaging title that is sure to please die-hard Bloons fans.

The popularity and success of Ninja Kiwi's recent Bloons game compelled the developer to put its next project on hold while they create another 50 levels to appease fans eager to pop More Bloons. But these levels promise to be even more difficult than the first batch.

There is something inherently gratifying about smashing or destroying something, even watching a building be demolished is good fun. So it should be no surprise that we see the concept come up a lot in games. Stephen over at Ninja Kiwi claims that his latest Flash game, "is based on the very simple fact that popping balloons is fun". And you know what? He's right! In Bloons you get to pop a lot of balloons!
