~ BTD6 description


Bloon Trap is the 4th upgrade of Path 3 for the Engineer Monkey in BTD6. It adds the Bloon Trap to the Engineer. Each Bloon Trap can trap up to 500 RBE worth of Bloons instead of 250 RBE in previous games. Additionally, a Bloon Trap will always spawn nearest the Engineer.

Bloons that come over it are trapped inside, though no money is awarded for individual bloon consumption. Like in BTD5, if the trap is collected manually, the player gets twice as much cash as the bloons would normally give; if not collected within ~15 seconds, or the Bloon Trap is upgraded to XXXL Trap, it will autocollect itself for only the original cash amount as if all bloons were popped normally. MOAB-class bloons and Camo Bloons (unless granted camo detection prior to deploying) will simply pass right through the Bloon Trap. Each trap can hold up to 500 RBE worth of bloons (530 with Bigger Traps). Once full, the Bloon Trap will shake to the left and right and emit an off-white colored aura. Bloon Traps deploy every 20 seconds, and once deployed the timer for the trap cooldown begins, although once the trap is used up it will take a minimum of 2.8s to deploy a new trap.

It costs $2975 on Easy, $3500 on Medium, $3780 on Hard, and $4200 on Impoppable.

Strategy[edit | edit source]

Summary[edit | edit source]

Bloon Trap is a viable option for bloon-popping and income generation. Although more difficult to generate income compared to its BTD5 counterpart, its production of Bloon Traps are more consistent. With a larger capacity compared to its BTD5 counterpart, it can also be used as a suitable exit-stopper.

Tips[edit | edit source]

  • Try to collect Bloon Traps manually as often as possible, as Bloon Traps do not profit when collected automatically. Additionally, no money is earned when bloons enter, and thus cannot return any money until collected.
  • The cooldown for Bloon Trap is 20 seconds, but if the old Bloon Trap expires after 20 seconds from deploying that Bloon Trap, a new Bloon Trap will immediately spawn.
  • Bloon Traps can be saved in save files. Therefore, they will not disappear when the game has been quitted and re-loaded again.
  • Monkey Farmers can actually pick up full traps similar to how they pick up bananas from Banana Farms and crates from Supply Drops, like in BTD5 Deluxe.
  • Use the 0-0-4 Bloon Trap, for as little bloon-popping as possible for maximum income, unless on the occasion where hybridizing offense with income is necessary. Crosspathing has little effect on the Bloon Traps, and crosspathing will worsen the money-generating functionality of Bloon Trap, as more bloons will simply be popped before the trap fills up.
    • In most situations, the 0-0-4 Bloon Trap is sufficient, unless the Bloon Trap is designed as a pseudo-Spactory, in which adding a crosspath can benefit the offensive attacks of the Bloon Trap Engineer.
    • Although 2-0-4 Bloon Trap decreases Bloon Trap cooldown from 20s to 16s, for the most part the income-generating portion of Bloon Trap worsens.
  • Buying and selling an Engineer with the Bloon Trap upgrade can spawn lots of Bloon Traps on the track. Use this to your advantage to ensure bloons do not progress easily.
  • Note that Bloon Trap won't give any money in Deflation Mode. It is entirely possible to buy-and-sell a Bloon Trap Engineer while keeping the Bloon Trap on the track, with the remaining Bloon Trap serving as a not-so-expensive safeguard for an exit.

Version History[edit | edit source]

22.0
  • Change balloon.png Bloon Trap now has a cooldown of 20s instead of capping at one new trap per round. Bloon Trap cooldown now starts upon once its spawns rather than once it is collected. Does not affect the existing 2.8s cooldown while refreshing a trap.
    • Note: Bloon Trap is still limited to 1 at a time per Engineer
  • Buff.png 2-0-4 Faster Engineering reduces Bloon Trap cooldown from 20s -> 16s. Does not affect the existing 2.8s cooldown per trap.

Trivia[edit | edit source]

  • The appearance of the trap is likely a reference to the Ghostbusters' Ghost Trap.
  • The upgrade icon shows the engineer either standing on the trap, or violently kicking it.
  • It makes an eerie electronic humming sound every time it traps a bloon inside.
  • Before update 12.1, if a Bloon Trap Engineer was affected by Gwendolin's Heat it Up ability, the game would crash.
  • Similar to BTD Battles, if the Tower is sold in BTD6, the trap will still remain on the ground and keep trapping bloons. But sometimes it will try to find a newly placed Bloon Trap Tower as if the trap is created by the tower. So the new Engineer cannot generate a new trap unless the trap on the ground is filled, and the pops by the trap will be counted to the Engineer.
  • A Monkey Knowledge Point called "Big Traps" increases the RBE limit to 530, but it erroneously states it can hold 280 RBE.
    • This has been fixed in the 13.0 update.
  • As of Version 13.0, the description was changed from "... Tap to..." to "... Select to...", so as to provide a device-neutral description for the Bloon Trap upgrade.
  • On Version 19.0, all Bloon Trap Engineers always will produce a new trap every time they are upgraded to the Bloon Trap upgrade, rather than only placing a new trap if there are greater than the current numbers of Bloon Traps placed on the map. This does not occur for XXXL Trap. This can be seen here.
