Biomes
Unrailed 2: Back on Track has five distinct biomes to play on. Each has its own attributes that make the gameplay unique. These attributes come in the form of varying terrain generation, different creatures and a final boss.
Players can choose which biome to start in, but typically starting in Monorail Meadows is the easiest. Players are able to progress between biomes choosing to navigate to the Biome Junction Station at the cost of 10. Navigating to the biome junction is only possible after completing 4 levels in the current biome. Selecting the biome junction will begin the current biome's boss fight, and after the player(s) defeat the boss, they can choose to navigate to the subsequent Biomes.
