Bloons Tower Defense 4 is a strategy game where you stop waves of balloons (called “bloons”) by placing monkey towers along their path. New to this version are tougher bloons like MOABs and BFBs, along with more towers and upgrades to outsmart them. The goal is to pop every bloon before it escapes—no easy task, as later rounds introduce camouflaged, lead-lined, and giant bloons that demand clever defenses. Bloons Tower Defense 4 is the fourth installment of the popular Bloons Tower Defense series, released on October 26, 2009. Made by Ninja Kiwi. Now it is playable again online. Play it on kbhgames.com for quick access to this mix of fast action and long-term planning, perfect for fans of challenging, brainy games.
