"APICO is a game about breeding, collecting, and conserving bees!"
In the game you come across over 30 different species of bee - some naturally found in different Biomes, others can only be found by Cross-Breeding species together to form new ones under different conditions, and some have their own unique ways of being found!
Tier 4 is made up of bees found through Cross-Breeding Tier 3 bees together, as well as a native bee found in the Hallows.
Tier 4 introduces bees that have traits at the absolute limits (i.e. 1 and 7).
Tier 4 also introduces bees that have special Area of Effects that will effect other bees, such as the Arctic Bee which acts as a Cooler.
Tier 5 contains special bees found as part of the story or through secrets. tier 5 bees cannot be found through cross-breeding or in the wild.
