Factory Biome is a unique biome in PokéRogue that players can randomly access through Power Plant. Steel-type Pokémon are predominantly found in this biome, and players will have the opportunity to catch common Pokémon such as Machop, Magnemite, and Voltorb, as well as rare Pokémon like Metagross and Genesect. Factory Biome also features stationary Gym Leaders, such as Byron and Jasmine, that providing a challenging and enriching battle experience. As players level up, Pokémon appearing in the biomes may be in their evolved forms, adding to the fun and variety of exploration. In Classic Mode and Daily Run, the biomes change after every 10 waves, while in Endless Mode, this change occurs randomly between waves 1 and 4.
