The fifth installment of Ninja Kiwi's popular tower defense game, Bloons Tower Defense. Pop wave after wave of colorful balloons by strategically placing monkeys and weapons on the map. Use dart monkeys, tack towers, sniper monkeys, boomerang throwers, bomb towers, ninja monkeys, glue gunners, and more to prevent the balloons from reaching the end of the track. Balloons of different colors not only have multiple layers, but also move at different speeds. Each monkey/tower has a unique upgrade path so that you make them more effective against their helium-filled enemies. You can also have your monkeys target the first, last, closest, or strongest balloon of a wave.
