Bloon Trap is the Engineer Monkey's path 3 tier 4 upgrade in Bloons TD 6. It allows the Engineer Monkey to deploy traps onto the track which collect and insta-kill Bloons. Outside of CHIMPS and Deflation modes, the Bloon Trap provides +100% more cash than usual from Bloons that it collects. The traps do not affect MOAB-Class Bloons.

Mechanics

Traps collect any non-MOAB-class Bloons that touch it, instantly popping them. Traps do not affect MOAB-Class Bloons. By default, traps will be placed on the nearest part of the track to the Engineer Monkey, including over walls and obstacles. If no part of the track is within its range, the Engineer Monkey will not deploy a trap unless given the Larger Service Area upgrade and the trap is retargeted.

Bloons popped by traps do not provide cash right away. Each trap can hold 500 RBE (530 with Big Traps). Once full they no longer pop bloons, and are ready for collection. Collectible traps will shake, and can be collected by moving the cursor over them, or collected automatically after some time. They can also be collected by Banana Farmers and Monkey Wall Street. Once collected, the trap provides the player with as much cash as all the trapped Bloons are worth, plus an additional 100% cash value if not playing in CHIMPS mode. This additional income can be increased further by Monkey Town, Monkey City, and Rubber to Gold. The Engineer Monkey cannot deploy another trap until the existing trap is collected.

The Engineer Monkey deploys a new trap 12 seconds after a trap is collected, which can be decreased by attack speed buffs but cannot be decreased below the minimum trap delay of 2.8s. The deploy speed is reduced to 6s and the minimum trap delay is decreased to 2.1s with the Faster Engineering upgrade.

If upgraded to Larger Service Area, the Engineer Monkey's trap location may be retargeted to anywhere within its range, including over walls and off the track. If upgraded to Deconstruction, the trap will de-fortify any Fortified Bloons before collecting them, letting it catch more Bloons should any Fortified Bloons enter the trap.

Traps can collect any Bloon type including Lead. However, traps cannot collect Camo Bloons unless the Engineer Monkey was provided camo detection when the trap was deployed. Providing the Engineer Monkey camo detection after a trap is deployed will not grant the trap camo detection; the Engineer Monkey will need to place a new trap before its trap can collect Camo Bloons.

Upon reloading a save file, any traps that existed when the game was saved will remain. However, buffs such as Monkey City and Camo detection will not be saved for traps.

Strategy

Outside of CHIMPS and Deflation modes, Bloon Trap is an excellent money-making tower which also helps defend against the Bloons. It is most effective between rounds 34-60, because on round 61 onward the amount of cash per Bloon is drastically reduced, and in the very early rounds there are not enough Bloons to justify the trap's use. It tends to stand out on Boss Bloon Events, which heavily demands maximizing income over rounds.

To maximize trap income, one should make sure as many Bloons as possible are collected by the trap instead of being popped by other towers or even the Engineer Monkey's own nail gun. The most effective way to do this is with the Larger Service Area upgrade, and targeting the trap as close to the entrance as possible. This upgrade also allows retargeting the trap to catch any Bloons that make it farther down the track after the first trap is full. When using Bloon Trap for income, one should avoid infinite-range towers such as Sniper or Druid of the Jungle because they will pop Bloons before they can enter the trap.

Faster Engineering usually hinders income unless the Engineer Monkey is placed behind an obstacle, because the Engineer Monkey will deploy sentries that pop Bloons, reducing the income from the trap.

Trap income is significantly increased by the Monkey Town and Monkey City Village upgrades, generating approximately 68% more income when under Monkey City. Income is increased further if collected Bloons are affected by the gold potion from a Rubber to Gold Alchemist.

Bloon Trap is a poor choice in CHIMPS and Deflation Modes, as it generates no additional income and the trap is outclassed by most other towers in terms of damage.

Version 13.0

•  Traps no longer collect for reduced cash when under a Monkey Town (bug fix)
•  Traps should collect for the correct amounts after resuming save (bug fix)
•  Traps will no longer allow bonus traps to be placed when reloading save (bug fix)

Version 20.0

“

Continuing our efforts to make crosspaths meaningful and fit the style of each path more solidly, a number of crosspath and base level balance shifts were made.
— Update notes

”

1-0-4, 2-0-4

•  Oversize Nails crosspath now allows Sentries to pop frozen Bloons
•  Oversize Nails crosspath now increases Sentry pierce by 1

Version 22.0

“

Some big buffs to Bloon Trap so it can now be used more effectively
— Update notes

”

•  Can now spawn multiple traps per round, at a cooldown of 20 seconds for a new trap

Version 23.0

“

Finally last update we allowed Bloontrap to be set multiple times per round, and we wanted to stay on the side of caution with a long cooldown, but after seeing it in the wild we are happy to make this cooldown faster.
— Update notes

”

•  Bloon Trap: trap cooldown reduced ― 20s → 15s

2-0-4

•  Faster Engineering: rate buff to Bloon Traps increased ― 0.8× → 0.6×

Version 26.0

“

Bloon Trap redeployment rate has also been buffed a fair amount.
— Update notes

”

•  Redeployment cooldown reduced ― 15s → 12s
  •  Also affects 2-0-4 redeployment cooldown ― 9s → 7.2s

Version 29.0

“

we have also re-envisioned the ‘Larger Service’ crosspath as giving smarter service as well in the form for targeting for Bloontrap & Cleansing Foam
— Update notes

”

•  Overall cost reduced by $50 (due to cost changes for previous tiers)

0-1-4, 0-2-4

•  Trap attack: Manual targeting option added

Version 30.0

“

To add a bit of quality of life solving problems with trap needing to fill once before moving to target location, Bloontraps placed off-track never being able to fill, and maybe even to just add some interesting micro, any Bloontraps will now become expired after a short delay when their Engineer has a new target set.
— Update notes

”

0-1-4, 0-2-4

•  Trap attack: Picking new target now destroys the current trap and places a new one

Version 31.0

•  Bloon Trap issue resolved on Sunken Columns with Bloontraps falling under the map in certain location (bug fix)

0-1-4

•  Bloon Trap issue resolved with certain conditions causing Bloontraps to repeatedly auto-collect even while empty (bug fix)

Version 36.0

“

XXXL Trap 205 crosspath hasn’t actually ‘been working’ due to the base attack rate being faster than minimum deployment delay so we have slowed the base rate to make 205 crosspath actually matter. Along with this, since the fortification bonus aspect of x2x hasn’t ever done anything for Bloontraps, 024 will now ignore the fortification of Bloons that it eats
— Update notes

”

0-2-4

•  Deconstruction now allows traps to defortify anything it consumes prior to capturing

Version 41.0

“

Lastly Bloontrap was rather unfairly able to steal all cash in Co-op games; we want to avoid dividing one player's farm earnings between the group entirely, but decided on a compromise here to prevent it from stealing that base amount.
— Update notes

”

•  Bloontrap now divides the base value of absorbed Bloons between all players when collected, any extra multiplied value is fully granted to the owner of the Bloontrap
  • Note: Overall buff for co-operative gameplay, a nerf to the Bloon Trap user

Version 43.0

“

While better than many options, base Engineer still takes a lot of available starting cash so the cost is reduced slightly [...] with a reduction to Double Gun’s price to reflect the lower value of the base tower.
— Update notes

”

•  Upgrade cost increased ― $3,500 → $3,600
  •  Overall cost is unchanged (due to cost changes for previous tiers)

Version 46.0

“

Middle crosspath feels too good for Bloontraps because of the massive quality of life it brings, so we’re pushing the DPS more for top crosspath by allowing Double Gun to also double the projectiles of Sentries.
— Update notes

”

•  Trap: Disappears when the Engineer is sold or sacrificed. No cash will be collected from the trap. (bug)
  • Note: This behavior is intended for Tier 5 but not for Tier 4

1-0-4, 2-0-4

•  Double Gun Sentries now shoot two projectiles at once

Version 46.2

1-0-4, 2-0-4

•  Sentry: Double Guns upgrade no longer reduces their pierce ― 2 → 3 (bug fix)

Version 47.0

0-1-4, 0-2-4

•  Bloontrap cooldown should no longer break depending on upgrade order (bug fix)
  • Note: Larger Service Area no longer bypasses minimum trap delay (2.8s)

Version 48.0

“

Really only one major change here; a rebalancing to how the 2xx Crosspath applies across various engineer upgrades, and some base stats being changed to accommodate fitting this.
— Update notes

”

2-0-4

•  Trap: Replacement delay reduced ― 2.8s → 2.1s

Version 54.0

X-1-4, X-2-4

•  Bloon Trap now correctly moves on target point set after loading a save (bug fix)
