Unfair Share

 is an Advanced Co-op Mode track that is exclusive to Bloons Tower Defense 5 Mobile in version 2.0 (August 26, 2013).

Overview
Which side is better? Left or right? The player and their ally must struggle to fend off the bloons in a track with five trees, striped grass, bushes surrounding the path, a few clovers, and a sidewalk path on the left side, which overall, looks clean. There are three trees, the grass is slightly darker, there are more clovers, small sticks, rocks, flowers, and a dirt path on the right side, which overall, looks a bit polluted. In the middle stands a white fence. The left path has more room for towers, but the right path is noticeably longer.
