The Bloons TD 4 Era or BTD4 Generation (sometimes shortened to BTD4) refers to games that use the same primary gameplay elements as Bloons Tower Defense 4. The main game in this period is Bloons TD 4 along with its expansion. Some include Bloons Super Monkey in the Bloons TD 4 generation. Even though it is not a tower defense game, many of the enemies, characters, projectiles and upgrades are directly based off of BTD4.

This generation brought a vastly increased tower roster, linearized upgrade paths, and an attempt to imitate three-dimensionality in its smooth shaded graphics. Building on the success of previous generations, BTD4 helped bolster the popularity of the Bloons line by appearing on Flash websites like and Newgrounds.

Though the game is no longer available online, many fans will frequently revisit the title on nostalgia Let's-Plays or for fun through the mobile app or flash archive.
