Be Unprepared! is a game mode in which you are supposed to purposefully place your towers so as to try to let the bloons escape. As you progress through a game in this mode, you will be given more towers (specific ones) after some of the rounds. You will be required to place these towers before the next round can start. The path the bloons take will change every round, so you have to reposition your towers before each round. In this mode, you don't have lives. Instead, you are required to let a certain number of bloons escape in each round. If you don't allow the required number of bloons to escape, you lose. Cease fire! is disabled in this mode.
