On this page of the Biomutant guide, you will find information on how to use the Fast Travel system. We explain how to unlock fast travel, when you can activate it, and whether using fast travel is free.
The fast travel option will become available shortly after exiting Bunker 101, the game's starting location. This is when the game world will open up, giving you a lot of freedom in its exploration.
Signposts are associated with fast travel - an example is shown in the picture. You will recognize them by the yellow flag. Signposts can be found near the majority of the unique locations. Eventually, you will discover dozens of them in different parts of the world.
Approach a signpost to activate it. From that point on, it becomes available for fast travel.
You don't have to get to the signposts to use fast travel. You can simply open the world map, hover over the signpost you are interested in, and press the button to use fast travel. It is free and does not consume any resources.
Inactive fast travel points, such as those near outposts or forts, may also appear on the world map. Depending on the type of location, you can unlock fast travel by visiting or conquering a given location.
Unfortunately, the game doesn't show all the signposts on the world map that are not yet unlocked. You can find them as you explore the world.
