Twin Guns is the Monkey Sub's path 3 tier 1 upgrade in Bloons TD 6. It doubles the attack speed of Monkey Sub's darts, reducing its attack cooldown from 0.75 to 0.375 seconds.

Crosspathing additionally reduces cooldown of its other attacks:

• Ballistic Missile reduces the attack cooldown of its missiles by 12.5%, increasing its attack speed by ~14%
• Submerge and Support reduces the cooldown of its pulses by 30%, increasing its attack speed by ~42%. The same applies to Bloontonium Reactor's radioactive damage pulses.

Strategy

This section was last updated for: version 53.2

Twin Guns gives a significant DPS boost to the Sub, in addition to improved consistency because of its increased attack speed. Despite costing more than a second 0-0-0 Sub, it's very much worth upgrading to 0-0-1 in CHIMPS if planning for an early Airburst Darts, which carries the early-game. For crosspathing purposes, it is the only meaningful crosspath for Submerge and Support, recommended for Bloontonium Reactor outside of Race Events, and recommended unconditionally for Energizer. Twin Guns is also recommended for Ballistic Missile and its succeeding upgrades on maps where their base range reaches all lanes, though upgrading further to Airburst Darts is preferred for more reliable cleanup.

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

”

0-3-1, 0-4-1

•  Ballistic Missile: Attack cooldown reduced ― 1.3125s → 1.1375s

Version 26.0

0-3-1, 0-4-1

•  Ballistic Missile: attack cooldown reduced ― 1.1375s → 0.9669s

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

”

0-3-1, 0-4-1

•  Missile attack: Attack cooldown reduced ― 0.9669s → 0.8702s (attack speed increased by 11.11%)

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. — Update notes

”
