Medium Difficulty

The Medium Difficulty icon in Bloons Tower Defense 4

Medium Difficulty is a Difficulty in the Bloons Tower Defense series, making its debut in Bloons Tower Defense 2. Towers are fairly priced in Medium. Medium Difficulty gives the player 75% as many lives as Easy Difficulty, and 150% as many lives as Hard Difficulty (150 Lives). Medium difficulty is well suited to intermediate players. To pass Medium Difficulty in BTD4, the player must complete Round 60 which happens to be the first round with a B.F.B.. Some players think of it as the boss of medium difficulty. Easy and Hard do not have a single "boss" for their final level, just a very tough round. Other difficultys.
