Because there are fewer rounds in Bloons Monkey City, the Banana Research Facility brings $300 per box instead of the normal $200, giving a possible total of $3000 per round, if all banana boxes are collected. Also, due to the competitive nature of Bloons TD Battles, each box grants $600 instead of $200, and that the Banana Research Facility brings a total of 6 boxes per round instead of 10.
