Volcano Terrain's biggest hurdle is losing Villages for major supports, as well as Ice in the multiplatform version of Bloons Monkey City (due to Absolute Zero). Another issue is the reduced land space, which is further worsened on DNA and Keyhole. Keyhole is one of the most difficult of all single-lane tracks in the game, having few vantage points and coverage. Use Banana Farms to compensate a lack of discounts.
