Bloons Tower Defense 2
Hot on the heels of the original Bloons Tower Defense game comes a sequel, appropriately named Bloons Tower Defense 2, 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. The difference between the difficulty levels lies in the number of lives you start with and the cost of the towers, with the fewest lives and the most costly towers available on the hardest level. And the update promises to provide a greater challenge than the first one did.
If you're a Bloons fan, that probably spells many more hours of lost productivity that Stephen and Chris Harris of NinjaKiwi have a knack for causing with their hit-after-hit string of game releases. More addictive than a barrel of super monkeys.
