Seems like Mexico is now burst of Bloons! Explore 4 brand new crazy fun tracks. Mesmerize yourself on the Sandy Spiral Track, get lost in the Subterranean Sewers, explore the secrets of the Monkey Temple, or challenge your wits on the Triangle of Insanity! Try a new game mode called Deflation mode. You start Deflation mode with 50,000 money but you never get any more. Unlock Tower Specialties after completing the new tracks in various difficulty levels. The specialties allow you to customize your strategy by making some towers much cheaper to buy, at the expense of increasing the cost of all others.
Control: mouse.
Select the track you want to play on then the difficulty. In the game buy your towers from the side bar on the right, then place them around the track to maximize their effectiveness. You will unlock new tower types with every rank you go up.
Have fun!
