Bloon Sends are groups of Bloons that can be sent to the enemy player in Bloons TD Battles 2. It has similarities to the old sending system implemented in Battles 1, with the key difference being that bloon send variants are limited but dynamically change as the rounds go on after 10 bloon sends become unlocked. Not only do sends become denser as rounds go by, certain bloon sends become removed during the game. Weaker bloons are available earliest in the game and stronger sends become available as the game progresses. Bloon Sends change the amount of eco the offender sends out; less deadly sends generally increase eco, while stronger sends often result in an eco penalty.
In Mobile, the player holds their finger on a bloon send to send multiple of the same type. There are more options to do the same thing on Steam; one can either click-and-hold the bloon send, or they can use hotkeys of a selection of available bloon sends, from the "A-S-D-F-G-H-J-K-L-;" range.
Bloon Sends
Each type of Bloon Send has a different amount of eco gain/loss, as well as a certain round availability range and "loading time per bloon" (written as "Loading time/bloon"). Grouped sends send faster and normally result in a greater change of eco, while spaced sends are slower but allows for sending stronger bloon types. Juggling between types of bloon sends is an
Non-blimp grouped sends increase eco faster but are sometimes less cost-efficient than equivalently available space sends at producing eco per dollar, while non-blimp spaced sends tend to have better economy but send slower. Blimps stronger than MOAB result in an eco loss, which results in a reduced income rate.
