Multi-Layer Battles

Multi-Level Battles will be a new feature of the next Bloons Tower Defense game. In multi-level battles, you will fight the bloons underground, on the land surface, and in the Sky. The paths on each level may be the same, or may be different. There will be a button that allows you to view all three levels, but you can only place things when a single level is shown on the screen (which can be done by clicking on one of the levels while you're on the multi-level viewing screen). At different points during the battle, bloons may come in only one level at a time, or in two or three levels at a time. Certain types of bloons will be able to move between levels, as well (for example, if a Helium Bloon spawns on the land surface, it will first float into the Sky before hitting the game camera). Certain towers will be able to attack bloons on multiple levels, or may be able to move between levels as well (though this may cost money in some cases). In addition, the Elevator Monkey will be able to move towers between the underground level and the land surface level, but not to or from the Sky level. Multi-Level Battles will be featured in many special missions, as well as some story missions; and some tracks (more difficult ones, mostly) will automatically be Multi-Level.
