For the first time in the history of Metro games, Metro Exodus presents open and extensive locations in the game. Along with this novelty, however, comes a problem - is there a fast travel system in the game, and can we move, for example, between the hiding places? The following page answers this question.
The short answer to the question is - no, there is no fast travel system in the game. Missions are constructed in such a way, however that travel is often accelerated a bit. No major spoilers - in the game, there are additional vehicles to travel, ropes on which we can descend to other parts of the map; we will also sometimes find ourselves at another location on the map.
Although the game does feature fast travel, it is worth spending some time exploring the game world, because, in Metro Exodus, you can discover some additional secrets (not all of them are marked on the map) and gain additional achievements.
