Version 4.7 is the third major update to Bloons TD Battles 2 and Bloons TD Battles 2+ of 2025. It introduced a new map, Splashdown, several changes to Scientist Gwen's Bloon Lab, additional text emotes and increased slots for them, and some balance changes. It has an OTA update that fixed an issue with the new changes.
A new Advanced tab has been added to the Scientist Gwen’s Bloon lab for more niche and complex controls.
The Round Stall Amount slider simulates how far the opponent’s natural bloons travel along the track before being popped so you can test strategies in stalling and anti-stalling scenarios.
The Opponent Hero panel allows you to simulate an opponent using Agent Jericho, Highwayman Jericho, and Star Captain Jericho. The opponent hero’s passive abilities (such as bloon adjustment) will be applied to your rounds and you can activate their abilities against yourself (where relevant).
The Rush Recording panel allows you to record your bloon sends and play them back against yourself, allowing repeated testing against the same rush or more complex rush layering.
In addition to the Advanced Tab controls, there is now an option in the Control tab to disable all monkeys when you fall below zero lives in order to see the exact state of your defence[sic] at the moment it failed.
The speed control in Scientist Gwen’s Bloon Lab has been moved off the central column and onto the main panel alongside the controls for removing monkeys, resetting cooldowns, etc. This is to prevent it conflicting with the UI from Star Captain Jericho’s Smuggler’s Run ability.
While Boomerang Monkey is intended to primarily be an early game tower, it has felt a bit underpowered in the late game, particularly the x4x and x5x. We are adding this change from Battles 1 to give it a little boost. — Update notes
The xx4 Sub is very strong at all points in the game. We are moving some of its damage to be MOAB exclusive and increasing its cost slightly to hinder its ability to defend by itself. — Update notes
Beetienne was mistakenly giving a damage buff in addition to the speed buff while Defend the Hive was active. This has now been removed which significantly lowers his ability to solo rushes using his ability. — Update notes

Defend the Hive: no longer grants +2 damage (bug fix)
While heroes who have clear synergies with specific towers are generally a good thing, Striker Jones in particular has been over reliant on Bomb and Mortar which has made him an unpopular hero. We have changed several of his upgrades so that they no longer do nothing if Bomb/Mortar are not present and added a secondary effect to his Artillery Command so that, while he’s still better with his favourite towers, he is capable of functioning without them. — Update notes

Similar to Striker Jones, Biker Bones relied too heavily on Bomb and Mortar to be useful and Striker was the better choice if you wanted to use those towers. With that in mind, we are reworking Bones so he leans much harder into the “Biker” part and synergises with vehicle towers, specifically Heli Pilot and Monkey Ace. As these towers do not specialise in explosive damage, there was no need for Biker to bypass explosive immunities so those upgrades have been replaced. In addition, Concussive Blast now targets the strongest bloon again. We were hoping the dense targeting would differentiate Biker from Striker but in practice it made the ability much less reliable and therefore worse. — Update notes
