Least Cost CHIMPS

Least Cost CHIMPS, or LCC for short, is a fan-made challenge consisting of beating CHIMPS with the least money spent. It is tracked in the BTD6 Index.

Strategy
The core intent of Least Cost CHIMPS is to stretch the potential to minimize cost on CHIMPS Mode on each map. From there, recorded LCC attempts may be used to measure the maximum amount of leeway possible. Combinations of strenuous penny-pinching, intense micromanagement, and analysis of powerful synergies form a majority of all community-collected LCC attempts. In terms of value in the BTD6 community, it challenges players towards the aforementioned extremes while also outputting valuable information that could potentially be usable in analyzing perfect defenses.

Tips

 * Extensive, optimized use of a Hero is a must, as they have minimal placement costs and upgrade themselves to become more powerful for free.
 * Admiral Brickell is a commonly used hero for LCC runs due to her flexibility with her various different attacks, as well as maximum stockpiling potential. More notably, her Mega Mine ability is used to obliterate high-HP targets while Ground Zero cleans up the weaker offspring.
 * Striker Jones with MOAB Mauler spam was formerly a very powerful combination for LCC attempts, but is much weaker due to the Mauler's bonus Ceramic damage nerfs and slight overall pierce and price nerfs.
 * Etienne is used on some harder maps thanks to his global camo detection and UCAV ability.
 * Perma-Spike is a common sight due to it being effective against rushes in general for only a middle-of-the-road cost, enhanced even further when cheap stalling tactics are employed alongside it to maximize its spike piles, in addition to having full uptime with Acidic Mixture Dip.
 * Ground Zero is common in a lot of easier Least Cost CHIMPS challenges due to its high microability and an ability capable of nuking the whole screen.

Trivia

 * The cheapest ever LCC was $19,120 on Logs, done on Version 18.0. That specific LCC is no longer possible due to the Brickell leveling speed bug being fixed in 18.1.
