Underground/Strategies

This page discusses strategies for the track Underground.

General Tips

 * The map has rotational symmetry. This means that the entrances are exactly 180 degrees from each other. Plan your setup with that in mind.
 * Both paths are active at once, so plan accordingly.
 * There is a lot of space for Banana Farms left and right of the paths.
 * Because of the Version 25.0 Wall of Fire placement buff, 0-2-x Walls of Fire placed on the two intersections can be reliable in the early-game for both odd and even rounds. Walls of Fire automatically target the closest bloon track by default, and this will guarantee spawning those blazes on those intersections, perfect for cleanup purposes. 1-2-0 Wall of Fire is ruins this, however.
