BTD Battles 2 Patch Notes 4.7 – March 17, 2025

New Features

• New Map: Splashdown

• Dive into an all new, water focussed map.
• Splashdown will appear in ranked and clan games in White Wasteland and higher.

• Advanced Bloon Lab Features

• 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 at the moment it failed.

• New Text Emote Slots

• We are increasing the number of Text Emote slots from 4 to 8.
• All players will also receive 4 new text emotes for free: “Yes”!, “Awesome!”, “Oh No!”, and “Ahh!”

General Changes

• Bloon Lab Speed Control

• 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.

• Tech Bot and New Abilities

• Abilities unlocked on a tower after it has been linked to a Tech Bot will not auto activate by default.
• This is to stop situations like Agent Jericho firing his MOAB Decoy the moment he hits level 10 because he was linked to a Tech Bot for Seize Assets.

Balance Changes

• Boomerang Monkey

• x4x Boomerang Monkey now gains camo detection during its Turbocharge 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.

• Monkey Sub

• xx4 Armor Piercing Darts damage (after split) 3 -> 2
• xx4 Armor Piercing Darts MOAB damage (after split) 0 -> 1
• xx4 Armor Piercing Darts: $2800 -> $3200.
• 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.

• Dartling Gunner

• x5x M.A.D. Rocket MOAB damage: 500 -> 450.
• x5x M.A.D. Rocket Storm MOAB Damage: 12 -> 60.
• This change from BTD6 should help the M.A.D. ability feel more impactful.

• Banana Farm

• 240 IMF Loan crosspath: End of round bonus $550 -> $700
• 250 Monkey-Nomics: End of round bonus $550 -> $1000.
• We are buffing the monkey bank top crosspath to make it a more tempting option when compared to the bottom crosspath and Quality Soil.

• Beetienne

• Level 3: Defend The Hive damage boost +2 -> +0 (bug fix)
• Level 17: Defend The Hive damage boost +3 -> +2
• 💭 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.

• Striker Jones

• 💣 Level 4: 10% attack speed boost for Bomb Shooters and Mortar Monkeys now applies to Striker Jones as well.
• 💣 Level 7: 25% blast radius increase for Mortar Monkeys now applies to Striker Jones as well.
• 💣 Level 8: +15 range and +40% pierce boost for Bomb Shooters and Mortar Monkeys now applies to Striker Jones as well.
• ⏳ Level 10: Striker Jones now gains 4x attack speed, 200 range, and +10 MOAB damage for 7 seconds as part of his Artillery Command ability. This is in addition to firing all Bomb and Mortar abilities for free.
• 💣 Level 18: 15% attack speed boost for Bomb Shooters and Mortar Monkeys now applies to Striker Jones as well.
• 💣 Level 20: 2x damage and pierce for Bomb Shooters and Mortar Monkeys during Artillery Command now applies to Striker Jones as well. Ability duration 10s -> 7s.
• 💭 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.

• Biker Bones

• 🎯 Level 3: Concussive Blast now targets the strongest bloon on screen, not the densest cluster. The ability icon and projectile graphics have also been updated to be more relevant.
• 🚁 Level 4: 10% attack speed boost for Bomb Shooters and Mortar Monkeys now applies to Heli Pilots, Monkey Aces, and Biker Bones himself instead.
• 📈 Level 5: The reduction to black bloons explosive resistance is replaced by a +10% range and pierce increase to Biker Bones.
• 🔥 Level 7: The blast radius upgrade for Mortar Monkeys has been replaced by a flame trail weapon on all Monkey Aces and Heli Pilots. These monkeys will leave a trail of damaging fire wherever they move.
• 🚁 Level 10: Double damage for Bomb Shooters and Mortar Monkeys now applies to Heli Pilots, Monkey Aces, and Biker Bones himself instead. The ability icon has also been updated to be more relevant.
• 🚁 Level 18: 15% attack speed boost for Bomb Shooters and Mortar Monkeys now applies to Heli Pilots, Monkey Aces, and Biker Bones himself.
• 📈 Level 19: The removal of black bloon explosive immunity is replaced by a 10% range and pierce increase to all towers within Biker Bones’ range (excluding himself).
• 🚁 Level 20: Triple damage for Bomb Shooters and Mortar Monkeys now applies to Heli Pilots, Monkey Aces, and Biker Bones himself instead.
• 💭 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.

Bug Fixes

• 🔊 Fixed in game audio not lowering while watching a video from the news panel.

• 🤖 Fixed Tech Bot link lines not disappearing when restarting a Bloon Lab game.

• ❌ Fixed red X not ending the Tech Bot’s targeting mode when pressed.

• 🥚 Fixed Humpty Monkey animated avatar not having any eyebrows.

• ⚠ Fixed occasional error popup in the pre-game agent shop.

• 🐵 Fixed monkey names not refreshing properly when restarting Bloon Lab games.

Previously, a major Bloons TD Battles 2 update 1.5 added a new event (Speed Battles and Play with Fire), and Bling Season 6. Recently, BTDB2 update 1.10 also added a new hero: Agent Jericho. Unfortunately, players are still facing some issues with the game. Today’s BTD Battles 2 patch 4.7 will address a few of these issues.
