Bloon send

In Bloons TD Battles 2, the player can send groups of Bloons to their opponent during the game. Unlike in Bloons TD Battles 1, where bloon sends permanently stay unlocked after reaching a certain round, in Battles 2, the bloon sends available to the player change as the rounds progress. Weaker bloons get removed on later rounds, so the player only has access to up to 10 types of bloon sends at once, excluding variants. Like in Battles 1, each type of bloon send increases or decreases the player's eco by a certain amount. Each bloon send also takes a different amount of time to send out.

Each type of Bloon has up to 3 different send types: Spaced, Grouped, and Tight. The number of Bloons on the icon show the type of send. (1 Bloon = spaced send, 2 Bloons = grouped send, 3 Bloons = tight send.) Spaced sends are the slowest, but stronger bloons can be sent out. Grouped sends are faster and increase/decrease eco quickly. Tight sends send bloons extremely quickly and are used for quick rushes later in the game.
