Central Market is the fourth upgrade of Path 3 for the Banana Farm in BTD6. It greatly increases the amount of money generated by the Banana Farm, gaining an additional $900 at the end of each round, as well as increasing the income of Merchantmen by 10%. It costs $12,750 on Easy, $15,000 on Medium, $16,200 on Hard, and $18,000 on Impoppable.

StrategiesEdit

Akin to its prior upgrade, the Marketplace, Central Market makes it easy for a player to accumulate money to spend within the round with no input outside the purchase of the base Banana Farm and subsequent upgrades. This goal is further filled by the new perk of completing a round to gain an extra $900, in a similar fashion to how the Buccaneer's Merchantmen line behaves.

Consequently, the second perk for the Central Market is its ability to increase Merchantmen (and subsequent fourth and fifth tier upgrades) by a 10% margin. This has the ability to increase the gains of Merchantmen the equivalent of the Trade Agreements without having the Monkey Knowledge allocated to that piece of knowledge, as well as increasing the high profits of Favored Trades and Trade Empire by a considerable amount.

One major consideration for maximum efficiency of a Central Market place is how the $900 round completion bonus applies alongside Valuable Bananas. As it stands, Valuable Bananas does not apply to the $900 bonus in any way, as it is not considered a banana in its own right. This means that the only bonus given is to the 12 auto-collected Bananas, resulting in $300, or 15 Banana's equivalent, rendering it the inferior upgrade with Increased Production and Greater Production producing one Banana more than the equivalent from Valuable Bananas, making 2/0/4 Banana Farms the superior pick.

EfficiencyEdit

As can be seen from the tables above, a 2/0/4 Central Market has the greatest return per investment, and is the fastest to profitability.

TriviaEdit

  • Central Market, along with prior and subsequent upgrades Marketplace and Monkey Wall Street, take clear inspiration to the original versions of Banana Farms from Bloons TD 4.
  • For a time, the 10% income increase of Merchantmen, Favored Trades and Trade Empire was bugged and did not function in the slightest. This was fixed in Version 5.0
