The single-player campaign of Metal Gear Survive features a rather large open world that you can explore. Instead of running around everywhere on foot, you’ll probably want to fast travel between key locations at some point. This can be done after completing the tutorial and retrieving all the memory boards for Virgil.
The next main mission will task you with repairing a wormhole generator located in the Dust. Simply place a marker on your map and head in that general direction. You’ll have to fend off a group of Wanderers for two minutes as the wormhole generator gets reactivated. After those two minutes, it’ll become a warp point that you can use to fast travel back to your base camp or any other points you’ve unlocked on the map. Simply interact with the warp point, choose your destination, then press and hold the X button (or A button if you’re on Xbox One) to fast travel there.
Other warp points and wormhole generators will be indicated on your map as side objectives, which are recognizable by the blue markers instead of the yellow main story ones.
