About Sunken Columns

Sunken Columns rewards one simple idea: build at the intersections. The two lanes overlap at the big bends at the top and bottom of the map, so towers placed there hit bloons from both lanes, often more than once.

Put your hero and a Dart Monkey at the top intersection, add a Tack Shooter and Boomerang Monkey there too. Get camo by round 24, and a 0-3-2 MOAB Mauler or Glaive Ricochet for round 40. Finish with Glaive Lord or Tack Zone.
