Version 20.0

“

The cost efficiency of Sub Commander's +5 pierce favored low tiers more than we’d like. Fortunately other paths of sub don’t care so much about pierce, so as xx4 AP Darts gives its own large pierce increase we hope lowering the amount of this buff slightly will make driving to T4 more meaningful. — Update notes

”

Tiers	Changes
X-X-5 Sub Commander	Sub Commander buff: pierce bonus reduced ― +5 → +4

Version 22.0

“

Ballistic Missile previously had far too much attack speed added into the crosspath and was rebalanced for parity, but the overall performance loss from this was too much. Better balance will come from the base rate of Ballistic Missile itself. — Update notes

”

Tiers	Changes
X-3-X Ballistic Missile X-4-X First Strike Capability	Ballistic Missile: Attack cooldown reduced ― 1.5s → 1.3s
0-3-1 Ballistic Missile + Twin Guns 0-4-1 First Strike Capability + Twin Guns	Ballistic Missile: Attack cooldown reduced ― 1.3125s → 1.1375s
0-3-2 Ballistic Missile + Airburst Darts 0-4-2 First Strike Capability + Airburst Darts	Ballistic Missile: Attack cooldown reduced ― 0.984375s → 0.853125s
X-X-5 Sub Commander	Resolved some issues with xx5 Sub Commander not always correctly buffing the damage of x5x Pre-emptive Strike (bug fix)

Version 23.0

“

As Bloontonium Reactor rarely uses up enough pierce that the pierce crosspath would ever matter, a large chunk of this has been moved into the middle crosspath. — Update notes

”

Tiers	Changes
4-X-X Bloontonium Reactor	Damage pulse: base pierce reduced ― 70 → 50 Note: Does not affect Energizer (1000)
4-1-0 Bloontonium Reactor + Barbed Darts	Damage pulse: base pierce reduced ― 84 → 70 Note: Pierce bonus increased from +14 to +20
4-2-0 Bloontonium Reactor + Heat-tipped Darts	Damage pulse: base pierce reduced ― 84 → 100 Note: Pierce bonus increased from +14 to +50

Version 26.0

“

As Airburst Darts alone already gives a huge benefit to the tower regardless of not applying any crosspath buff, some of the attack speed benefit this upgrade gave to 032 Ballistic Missile has instead been moved into the base 030 Missile. — Update notes

”

Tiers	Changes
3-X-X Submerge and Support	Submerge and Support should no longer be possible to disconnect tower location from visible model (bug fix)
X-3-X Ballistic Missile X-4-X First Strike Capability	Ballistic Missile: attack cooldown reduced ― 1.3s → 1.105s
0-3-1 Ballistic Missile + Twin Guns 0-4-1 First Strike Capability + Twin Guns	Ballistic Missile: attack cooldown reduced ― 1.1375s → 0.9669s
0-3-2 Ballistic Missile + Airburst Darts 0-4-2 First Strike Capability + Airburst Darts	Ballistic Missile: attack cooldown reduced ― 0.853125s → 0.8702s
0-3-2 Ballistic Missile + Airburst Darts and further upgrades	rate buff to Ballistic Missile reduced from 0.75x to 0.9x
0-5-2 Pre-emptive Strike + Airburst Darts	Ballistic Missile: attack cooldown reduced ― 0.328125s → 0.39375s

Version 27.0

“

Ballistic Missile’s 230 crosspath has been in a confusing spot for a while where it functioned different to Advanced Intel, so it has been converted to function with Advanced Intel in the same way that any other Sub upgrade would. Additionally First Strike's secondary explosion has had its target count reduced slightly. — Update notes

”

Tiers	Changes
2-3-0 Ballistic Missile + Advanced Intel and further upgrades	Ballistic Missile: Now benefits from Advanced Intel's targeting in the same way as the main attack  Can now detect and hit Camo Bloons in range of towers that have Camo detection  No longer has infinite range; can only target Bloons in range of other towers
X-4-X First Strike Capability X-5-X Pre-emptive Strike	Ability: Secondary AoE pierce decreased ― ∞ → 80

Version 29.0

“

The logic on a Lead crosspath not being required to give Lead popping to an attack based on something weak against Lead has never sat right, so we’re finally sorting that out and making sub a little angrier. — Update notes

”

Tiers	Changes
4-0-X Bloontonium Reactor 4-1-0 Bloontonium Reactor + Barbed Darts 5-0-X Energizer 5-1-0 Energizer + Barbed Darts	Damage Pulse: Damage type changed ― Normal → Shatter Note: 4-2-0 and 5-2-0 damage type remains Normal

“

Increasing the strength of the basic Ballistic Missile attack on the Pre-Emptive Strike sub, so that it can bring a little more to the table after the initial single hit on each spawn. — Update notes

”

Tiers	Changes
X-5-X Pre-emptive Strike	Missile: Damage increased ― 1 → 10  Missile: Bonus ceramic damage increased ― +10 → +15  Missile: Bonus MOAB damage increased ― +10 → +15

Version 30.0

“

Previously the rate increase to Ballistic Missile from crosspath was reduced due to Airburst having enough value on it’s own. This reason still applies as Airburst provides a significant power boost just on it’s own, so all rate increase has been removed from Airburst and applied directly to the base Ballistic Missile to help crosspath diversity slightly. — Update notes

”

Tiers	Changes
X-3-0 Ballistic Missile X-4-0 First Strike Capability	Ballistic missile attack: cooldown decreased ― 1.105s → 0.9945s
0-3-1 Ballistic Missile + Twin Guns 0-4-1 First Strike Capability + Twin Guns	Ballistic missile attack: cooldown decreased ― 0.9669s → 0.8702s
0-3-2 Ballistic Missile + Airburst Darts 0-4-2 First Strike Capability + Airburst Darts	Airburst darts no longer reduces Ballistic Missile rate by 0.9x Note: Ballistic Missile attack remains at 0.8702s
X-4-X First Strike Capability X-5-X Pre-emptive Strike	Ability: Initial impact damage is now dealt before splash damage (bug fix)
0-5-2 Pre-emptive Strike + Airburst Darts	Ballistic missile attack: attack cooldown increased due to Airburst Darts crosspath change ― 0.39375s → 0.4375s

Version 31.0

“

Energizer upgrade offers nothing extra to the reactor sub aside from niche utility buffs, so we have increased the lategame cleanup potential by a large amount to help deal with Super Ceramics. — Update notes

”

Tiers	Changes
5-X-X Energizer	Pulse: Damage increased ― 3 → 5  Pulse: Now gains bonus Ceramic damage ― +0 → +5

Version 32.0

“

Similar types of camo reveal like Shimmer/Signal Flare/Embrittlement are all pierce limited, but the Submerge sub has practically infinite pierce while also being extremely cheap with a very fast rate and a T4 that is far better at camo removal than those other towers can reach. Giving this upgrade a more reasonable pierce value brings these more in line and allows for the pierce crosspath to have some potential meaning. — Update notes

”

Tiers	Changes
3-0-X Submerge and Support 4-0-X Bloontonium Reactor	Camo Pulse: Pierce reduced ― infinite → 100
3-1-0 Submerge and Support + Barbed Darts 4-1-0 Bloontonium Reactor + Barbed Darts	Camo Pulse: Pierce reduced ― infinite → 120

Version 34.0

Tiers	Changes
5-X-X Energizer	Energizer ability cooldown reduction for land towers increased ― 20% → 40% (bug)  Energizer ability cooldown reduction for water towers increased ― 50% → 70% (bug)

Version 34.2

Tiers	Changes
5-X-X Energizer	Energizer ability cooldown reduction for land towers decreased ― 40% → 20% (bug fix)  Energizer ability cooldown reduction for water towers decreased ― 70% → 50% (bug fix)

Version 35.0

“

You guys seem to think this would be nice, so here it is. — Update notes

”

Tiers	Changes
X-5-X Pre-emptive Strike	Ballistic Missile: attack splash radius increased ― 18 → 24

Version 39.0

“

The use of Pre-emptive with power mostly limited to damage only to top-layer leaves it in a small niche that can’t totally function on its own, so we’re slightly improving its ceramic cleanup and lowering the upgrade cost to allow more leeway for combinations to pair with it. — Update notes

”

Tiers	Changes
X-5-X Pre-emptive Strike	Upgrade cost reduced ― $32,000 → $29,000  Ballistic Missile: Bonus damage to Ceramic increased ― +15 → +20

Version 41.0

“

We have come back a number of times to add, fix & balance sub crosspathing, over years of learning though it currently feels messy and we’d like simplification. Heat-Tipped Darts doesn’t increase base sub pierce, so it feels silly to require it for maximum pierce on Submerged subs. Likewise Airburst shouldn’t be required to maximize the rate of submerged subs, instead we’d rather give people an easier way to work with the Airburst attack if they desire to upgrade to it so ‘Submerge’ is moving to a new Tower Special rather than target priority. Ballistic Missiles always had excessive pierce for what it is, so this is being cut back on. — Update notes

”

Tiers	Changes
3-X-X Submerge and Support	Upgrade cost increased ― $500 → $700
3-X-X Submerge and Support and further upgrades	Submerge targeting is now mapped to Monkey Special 1
3-1-0 Submerge and Support + Barbed Darts 4-1-0 Bloontonium Reactor + Barbed Darts 5-1-0 Energizer + Barbed Darts	Decamo pulse: Pierce increased ― 120 → 150
3-2-0 Submerge and Support + Heat-tipped Darts 4-2-0 Bloontonium Reactor + Heat-tipped Darts 5-2-0 Energizer + Heat-tipped Darts	Heat-tipped Darts no longer increases decamo pulse pierce by 30  Overall pierce is unchanged (due to changes to the previous tier)

Version 42.0

“

As currently nothing else ever happens with the main attack beyond T2 on the top path we want to give Energizer a little more power here to promote reason to un-submerge, although knowing how well this attack scales in terms of buffability we’re starting off with a careful amount to not take this too far. — Update notes

”

Tiers	Changes
3-X-X Submerge and Support 4-X-X Bloontonium Reactor 5-X-X Energizer Paragon	Retry Last Round no longer removes the submerge toggle (bug fix)
5-X-X Energizer	Main dart: damage increased ― 1 → 5
5-0-2 Energizer + Airburst Darts	Airburst dart: damage increased ― 1 → 5

Version 43.0

“

Bloontonium Reactor’s unsubmerged damage is increasing to encourage unsubmerged possibilities. The bonus to Lead on Reactor currently doesn't apply to T5, so this bonus is being carried up and improved along with a small price reduction to Energizer as strategies using it have fallen somewhat in viability. Nautic Siege Core’s hero buff is being improved as currently this is an under-utilized part of the tower. — Update notes

”

Tiers	Changes
4-X-X Bloontonium Reactor	Main dart: Damage increased ― 1 → 2
4-0-2 Bloontonium Reactor + Airburst Darts	Airburst dart: Damage increased ― 1 → 2
5-X-X Energizer	Upgrade cost reduced ― $32,000 → $31,000
5-2-0 Energizer + Heat-tipped Darts	Radioactive pulse: Gains bonus Lead damage ― +0 → +5
X-5-X Pre-emptive Strike	Pre-Emptive Strike: now works on Castle Revenge (bug fix)
Paragon	Hero buff: Attack cooldown increase reduced ― 1.5x → 1.3x  Damage multiplier increased: Hero buff ― 5x → 6x

Version 44.0

“

Given the long cooldown we want it to feel impactful in freeplay for longer, so all of the Nautic Siege Core’s ability boss damage is being converted to basic damage & bonuses to MOAB. — Update notes

”

Tiers	Changes
5-X-X Energizer	Buff icon now appears on X-4-X Beast Handlers
Paragon	Final Strike explosion: base damage increased ― 50000 → 60000  Final Strike explosion: no longer deals +10,000 bonus boss damage  Final Strike aftershock: base damage increased ― 10000 → 15000  Final Strike aftershock: no longer deals +5,000 boss damage  Final Strike fallout: bonus MOAB-class damage increased ― +60 → +90  Final Strike fallout: no longer deals +30 boss damage

Version 44.1

Tiers	Changes
2-X-X Advanced Intel	Shared range no longer breaks after loading a save then upgrading (bug fix)

Version 45.0

“

We’re improving Reactor’s attack cooldown to improve general consistency. Ballistic Missile struggles greatly against standard Bloons since almost all of its power is in the Ceramic/Moab bonus, so we’re also balancing this consistency out with greater damage to standard targets while retaining the same total MOAB-Class power at the cost of pierce. Sub Paragon unsubmerged form is overperforming, so we’re reducing the boss power of the main attack while greatly improving the less desirable submerged power. — Update notes

”

Tiers	Changes
All tiers	No longer displays a Paragon pip without all tier 5 upgrades unlocked (bug fix)
4-X-X Bloontonium Reactor 5-X-X Energizer	Pulse: cooldown reduced ― 0.3s → 0.28s

Version 46.0

Tiers	Changes
Paragon	No longer keeps its radiation attack while unsubmerged (bug fix)

Version 47.0

“

Price reductions for Energizer to reduce the cost of related build synergies. Armour Piercing Darts subs are generally a tough choice as even though their single target damage is greatly improved the pierce is lacking for the cost, so price has been reduced at T4 and T5 has been granted extra airbursts to make it more desirable an upgrade for dealing with higher pierce itself — Update notes

2-X-X Advanced Intel and further upgrades	No longer should have less range when targeting MOAB-Class Bloons (bug fix)

Version 51.0

“

Energizer’s cooldown reduction for nearby water towers has always felt excessive, so we’re dialing it back to 40%, still strong just not quite double uptime strong. Pre-Emptive Strike’s ability is getting a serious boost, both in raw damage and AoE, so hopefully the upgrade can finally feel like a significant step up. Finally Armour Piercing Darts, the upgrade that has had fans yelling ‘it doesn’t actually pierce armor!’ for years – it still won’t hit Leads (Not sorry). Now it grants bonus damage against Fortified targets. — Update notes

”

Tiers	Changes
5-X-X Energizer	Ability cooldown reduction bonus to nearby water towers decreased ― −50% → −40% Description changed ― Reduces ability cooldowns everywhere by 20%. While in radius, Heroes earn XP 50% faster and water Monkeys ability cooldowns are halved. → Reduces ability cooldowns everywhere by 20% and by 40% for Water based Monkeys. While in radius, Heroes earn XP 50% faster.
X-5-X Pre-emptive Strike	Ability: Damage to main target increased ― 10,000 → 20,000  Ability: Area of effect damage increased ― 350 → 1,000
X-X-4 Armor Piercing Darts	Description changed ― Special AP darts gain increased damage and popping power, plus additional damage to MOAB class Bloons. → Special AP darts gain increased damage and popping power, plus additional damage to Fortified and MOAB class Bloons.

Monkey Sub kept leaving bags of poop on our doorstep and will be gaining improved reliability for its de-camo pulse, with Reactor already doing very good at this and buildup growing more reliable from the change it gets a tiny price raise. — Update notes
