Banana Research Facility (BTD4)


 * Not to be confused with the track, Banana Factory.''

"High tech banana facility earns you a staggering 2000 money per round."

- Bloons TD 4 Description

The  B anana R esearch F acility (BRF) is the fourth and final upgrade to the Banana Farm in Bloons TD 4, giving $2000 money every round. It costs $8500 on Easy, $10000 on Medium, and $10800 on Hard. It is unlocked at Rank 28. This tower is important to get you far in the game as most towers will be near useless in later levels and the ones that make the most difference (Sun God, Laser Cannon, Tempest Tornado, etc.) will be really expensive, making them a big payoff.

Appearance
The Banana Research Facility is the only upgrade of the Banana Farm to have no open space. There is a grey rectangular prism at the bottom of the facility, it has a large light blue window, with two pipes on top of the right side and a cube on the left side that is similar to the base, with a banana sign on top.

How to Use

 * 1) Use this strategy for Medium or Hard. You will need to buy the Banana Farm in the early rounds (ideally before Round 10), and then upgrade it to Banana Plantation as quickly as possible. Then after 5 more rounds, you should try to buy Banana Republic. Then when you get to Round 40+, try to buy the BRF. This upgrade should be bought at or before Round 53 on Medium, or Round 57 on Hard. Let the money roll in!
 * 2) Getting ten of these in BTD4 will make the player get $20000 per turn and will allow the player to get tons of Sun Gods. (1 each round, in fact, assuming that the player already has a plasma monkey at the end of each round)

Trivia

 * In BTD4 iPhone/iPod, this upgrade is called 'BRF'.
 * Whether or not the Banana Research Facility is more useful in BTD4 or BTD5 is debatable, as in BTD4 it's cheaper, but in BTD5 it has the potential to make more money due to Valuable Bananas.
