~ In-game description

Banana Research Facility (also known as BRF) is the fourth upgrade of Path 1 for the Banana Farm in Bloons TD 6. Its bananas are replaced with banana crates, which produce more cash. Compared to its BTD5 counterpart, it produces income differently, creating 5 crates each worth $300 ($375 with Valuable Bananas), valued at up to $1,500 per round ($1,875 with Valuable Bananas).

This upgrade costs $16,150 on Easy, $19,000 on Medium, $20,520 on Hard, and $22,800 on Impoppable.

Banana Research Facility

Banana Research Facility upgrades the plantation of bananas into a banana production factory. It displays a banana logo at the front. There is a chimney that expels yellow smoke every so often, as well as a blue pipe at the factory's left (player's right) that chugs out liquid through it every so often too. The roof is slanted on the factory's right (player's left) and is apparently made of a long slab of concrete reinforced by three concrete sticks.

Banana Research Facility creates 5 banana crates instead of 16 bananas. Banana crates are worth $300 each, totalling $1500 per round if all crates are collected. With 4-2-0, this is $375 per crate increased to $1875 if all crates are collected.

Like all Banana Farms, Banana Research Facility generates crates evenly throughout a round with respect to bloon send duration on a percentage basis. On a "short" bloon send round, specifically those with dense bloon sends, all crates for that round are produced very quickly.

Targeting Priorities[]

Banana Research Facility produces crates that are tossed erratically around its range. Like most Banana Farm upgrades, Banana Research Facility lacks any real targeting priority.

Banana Research Facility is a very expensive income option compared to other games, but when crosspathed with Valuable Bananas, it becomes one of the most efficient short-term Banana Farm options in BTD6, especially when paired with the global Banana Central buff. Although players need to constantly collect crates, it is easier to micromanage than Banana Plantations. Banana Research Facility often competes with Monkey Banks, as the Bank is considerably cheaper, requires less micromanagement, and is easily spammable because of these two benefits. However, the BRF produces the highest amount of income per round for a single Banana Farm below Tier 5, making it the strongest at compact income generation. It is also the best farm for a Monkeyopolis because it is the most expensive.


  • Use the 4-2-0 crosspath for maximum income gain. It is far more efficient for gaining more income per round. 4-0-2 is worse for lazy farming than Central Market in terms of income-generating efficiency and cost efficiency unless the 4-0-2 BRF is buffed by Banana Central, in which the income generation surpasses a 2-0-4 Central Market even with the crutch of compensatory autocollection at a fraction of the original value.
    • Compared to the $1400 per round from a 2-0-4 Central Market, a no-manual 4-0-2 BRF nets a minimum of $1275 per round with time delay, while a no-manual 4-0-2 BRF buffed by Banana Central nets about $1594 per round with time delay.
  • Adding 4-2-0 Banana Research Facilities nearby a Monkey City in preparation for Monkeyopolis is very efficient for both maximal Monkeyopolis income production and the best Banana Farm when paired with Monkey City.
  • Major advantages of the Banana Research Facility is that they are the most space-efficient, and greatly benefit from being overclocked. They can also be buffed by Geraldo's Fertilizer.
  • BRFs produce 80% more crates when affected by Overclock, making overclocked BRFs one of the most cost and space efficient farming methods in the game.
  • BRFs are the most expensive Tier 4 banana farm, and should be the first choice for a Monkeyopolis.

Version History[]

Balance Changes[]

Banana Research Facility was nerfed too hard compared with its BTD5 counterpart when it was first released in BTD6, so a considerable price drop for this upgrade was made in Version 2.0 to make the Banana Research Facility become a highly cost-effective long-term income option. After the Monkeyopolis nerf in v32.0, it has become even more important for Boss events, because of its high income potential that gets further boosted by the Banana Central.

Initial release (compared to BTD5 Mobile)
  • NERF Banana Research Facility price increased ($14,000 → $22,000)
  • NERF Banana Research Facility crate value decreased ($400 → $300)
  • BUFF Banana Research Facility price decreased ($22,000 → $19,000)

Official artwork[]


  • The Banana Research Facility's logo is actually floating in mid-air, as there are no models for the supporting rods. This can only be observed through modding to enable tower rotation or free cam.
