A game drop[1] (or simply drop)[2] is a type of named update containing a number of features related to a theme. Three to four game drops are released each year in a quarterly schedule.
Game drops are loosely planned up to two years at most in advance, give or take, depending on community feedback.[3] A game drop can be small, like Bats and Pots, or large, like Chaos Cubed. Game drops can have any number of features, and can tackle any feature types.[4]
The game drop system was first announced with the release of Armored Paws. Bats and Pots was then retroactively called a drop. Due to being released after the announcement of the game drop system, Tricky Trials would also qualify as a drop but is not officially considered one.
For the most part, one game drop is released in each business quarter of a year.
