GTA: Bloons Tower Defense 2
The balloons contain some toxic gas and it would be hazardous to humans if they are expose to it. However, the monkeys are immune to the toxic gas somehow and they could puff those balloons in the air. No one knows why the balloons were developed to contain such toxic substance, but one thing is sure, the monkeys are here to stay and they won't let a single balloons reach the town. They were train to do one thing and that is popped those rouge balloons. Overtime, they develop some special skills and they become even better at popping balloons. Those toxic balloons are now known as bloons and the monkeys have developed into something more. They have lots of variation and each one of them have different abilities to popped those bloons. As the bloons become harder to popped scientist have evolve the monkeys to fight those bloons. This way, they won't have a trouble of popping those bloons as they are coming to the town. The battle between the bloons are becoming intense and it seems that the two are becoming more and more evolve to put a stop to one another. In this battle between bloons and the monkeys, you need to know where to place the monkeys to blow those bloons as they pass their way. You need money to upgrade and buy more monkeys. Each bloons would earn you money as you popped them. The idea here is to place the tower to where they can pop the most bloons. You can upgrade the bloons, but it would cost you a lot of money. The game would be harder and more challenging since the more advance bloons would be coming. And that is why, you would need to buy more and better monkeys to defend the town.
