"Sacrifice every tower type in the game to the Temple"

- Official BTD6 Description

 is an achievement in BTD6, introduced in Version 14.0. It is achieved by upgrading a Super Monkey into the Sun Temple while there is at least one of every tower in its range to sacrifice and then completing the round when that Sun Temple was bought. Earning this achievement awards 4 Instamonkeys - a 0-0-1 Boomerang Monkey, a 0-0-1 Monkey Ace, a 0-1-0 Druid, and a 0-0-1 Banana Farm.

Summary
Have plenty of space for the upcoming Sun Temple, and place every single tower type around its radius. Remember, there are 22 types of non-hero towers in the game, and some of them consume huge footprint, so lay one of each type out neatly but compactly. Use a map with very open space such as Firing Range.

Tips

 * It is probably easier to attempt this on Firing Range due to the sheer amount of space inside the map, alongside a bit of decent space for a Monkey Buccaneer and a Monkey Sub at the same time.
 * Ensure the Sun Avatar is 3-2-0 before attempting to achieve this achievement. Buff it with Stronger Stimulant and add any Monkey Village nearby the Sun Avatar.
 * The achievement is unlocked immediately after sacrificing to the Sun Temple. It is not neccessary to complete a round after the sacrificing.
 * Note that if the player fails to complete the achievement when creating a temple, the sacrificed towers are counted towards the achievement and do not need to be sacrificed again later.
 * Even though this achievement cannot be done in Sandbox Mode, it is worth experimenting sacrificing towers on Sandbox Mode to see if the Temple can sacrifice all tower types at once.

Trivia

 * Along with Snap of your fingers, this achievement references Avengers: Infinity War. After the snap, Thanos sees a vision of young Gamora, who asks him if he got what he wanted.
 * The same achievement used to be possible with Adora if she sacrifices one of every tower type in a single game, but this method has since been removed in Version 14.1.
 * There was a very minor bug where the name of this achievement had a colon at the end of the name. This was fixed in Version 24.0.
